The Crescent and Soap Bubble Nebula Shining in a Wide Scene from Ha and OIII Emission
The image shows an HaOIII wide field where NGC 6888 also known as the Crescent Nebula, seems to be immersed in. Even looking similar to a supernova remnant, The Crescent is indeed a relatively rare nebula that surrounds WR136 (HD 192163) a Wolf-Rayet dying star in the constellation of Cygnus. The gigantic bubble of gas it was formed by the stellar wind. The central star is releasing massive amounts of gas and UV irradiation, exciting oxygen and hydrogen to emit in the blue and red wavelength illuminating the nebula. The Wolf-Rayet star will probably end up exploding as a supernova within the next 100,000 years. Shinning against the background sculptured by a massive cloud of hydrogen from Cygnus region, is visible another small bubble, known as the the “Soap Bubble” a planetary nebula (PN G75.5+1.7) very faint visible in filtered OIII light. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal. This was also the “first light” from my new combo system from Player One Astronomy, the Poseidon-C Pro Camera and the new Anit-Halo PRO Dual-Band (Ha+OIII) 3nm filter and it works incredibly well!
PT: A imagem revela um campo amplo e profundo de HaOIII onde a NGC 6888, também conhecida como Nebulosa Crescente, parece estar imersa. Mesmo parecendo semelhante a uma supernova remanescente, a nebulosa Crescente é de facto uma nebulosa relativamente rara que circunda a WR136 (HD 192163), uma estrela “moribunda” Wolf-Rayet na constelação do Cisne. A gigantesca bolha de gás foi formada pelo vento estelar. A estrela central vai assim libertando grandes quantidades de gás e radiação UV, estimulando a emissão de oxigénio e hidrogénio no comprimento de onda azul e vermelho, que ilumina assim a nebulosa. A estrela Wolf-Rayet provavelmente acabará explodindo como uma supernova nos próximos 100 mil anos. Brilhando contra o fundo esculpido por uma enorme nuvem de hidrogénio da região do Cisne, é visível outra pequena bolha, conhecida como a “Bolha de Sabão”, uma nebulosa planetária (PN G75.5+1.7) muito fraca, visível na luz filtrada OIII (Oxigénio). A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal. Esta foi também a chamada “first light” do meu novo sistema substituto da DSLR, um combo perfeito da Player One Astronomy, a Poseidon-C Pro Camera e novo filtro Anit-Halo PRO Dual-Band (Ha+OIII) 3nm que se revelou verdadeiramente incrível!

Blueish Reflection Nebula VdB 152 Shining in Wolf’s Cave Region
A wide field view from Wolf’s Cave region, located in Cepheus constellation, shows the faint blueish reflection nebula VdB 152, shining at the tip of the long dark nebula Barnard 175, lying at a distance of 1,400 light-years away. Not far way to right, shines the colorful planetary nebula Dengel-Hartl 5. The wide field scene also covers the dense dark nebula, known as LDN 1221, visible at the top edge. The image was captured from Dark Sky® Alqueva Official Observatory, in Portugal, with my Canon 6D modified and comprise 25h of exposure in RGB light, and is a result of the first light while testing the Omegon 76ED Apo triplet. I had a technical issue with my Ha lights, so I was not able to use it and properly reveal the supernova remnant arc this time. Hope you enjoy it!

2023 Bright Perseid Meteor and a Persistent Train
A time lapse sequence captured during Perseids meteor shower 2023 from Dark Sky® Alqueva, in Portugal, shows a fast bright meteor traveling at a speed of about 60 kilometers per second, disintegrating while passing through the thin atmosphere at high altitude. Meteors can excite green emission from oxygen atoms releasing the color we see, originated from ionized chemical elements. Blue-green is typically originated from magnesium, nickel also glows in green color, while calcium is radiating violet. Immediately after explodes, this Perseid meteor was lingering a visible orange trail, known as a persistent train, which persists visible for a few minutes. According to Nasa, “the glow emanated from atoms in the Earth’s atmosphere in the path of the meteor – atoms that had an electron knocked away and emit light during reacquisition.” The time lapse shows the initial wind-blown displacement of these bright former ions, while the “orange smoke” dissipates and drifts away in the Earth atmosphere.
PT: Uma sequência time lapse captada durante a chuva de meteoros Perseidas 2023 a partir do Dark Sky® Alqueva, em Portugal, mostra um meteoro rápido e brilhante, viajando a uma velocidade de cerca de 60 quilómetros por segundo, desintegrando-se ao passar pela fina atmosfera em alta altitude. Os meteoros podem excitar os átomos de oxigénio liberando a cor verde que vemos, originada de elementos químicos ionizados. O azul-esverdeado é tipicamente originado do magnésio, o níquel também brilha na cor verde, enquanto o cálcio irradia na cor violeta. Imediatamente após explodir, este meteoro proveniente das Perseidas deixou uma trilha laranja visível, conhecida como “persistent train”, que persiste visível por alguns minutos. Segundo a Nasa, “o brilho emana de átomos na atmosfera da Terra que se encontram no caminho do meteoro – átomos que tiveram um electrão arrancado e emitem assim luz durante a reaquisição”. O lapso de tempo mostra o deslocamento inicial desses iões brilhantes, pelo vento, enquanto a “fumaça laranja” se dissipa e se afasta na atmosfera da Terra.

Sequence of a Super “Blue” Moon 2023 Rising Over Monsaraz Castle
A sequence of single shot shows a Super Full “Blue” Moon which don’t have nothing of blue, rising above Monsaraz castle at Dark Sky® Alqueva, in Portugal. Blue Moon is just called when two full moons happen in the same month. Supermoons happen when a full moon approximately coincides with the moon’s perigee, or a point in its orbit at which it is closest to Earth. This makes the moon appear larger and brighter than usual. Below is a time lapse of this singular moment, to watch with sound on.
PT: A sequência de disparos únicos, revela o caminho da Super Lua Cheia “Azul” – que não tem nada de azul – nascendo sobre o castelo de Monsaraz, no Dark Sky® Alqueva, em Portugal.

As superluas ocorrem quando a lua cheia coincide aproximadamente com o perigeu, ponto da sua órbita mais próxima da Terra. Nesta alturas a lua parece maior e mais brilhante do que o normal. Em baixo é possível ver um time lapse deste momento singular, para ver com o som ligado.

A Large Solar Filament 29x the Size of our Planet Earth
On 31th of July 2023, a huge filament was visible on the sun’s disc center. At first sight and according to the size, it seems to fit in a quarter of the solar diameter, which will probably indicates a size of around 370,000 km or 29x the size of our planet Earth. Solar filaments are clouds of ionized gas, or plasma, as seen in contrast above the chromosphere. When a solar filament is seen near the solar limb, then it is called a “prominence” instead of a filament. Prominences contain much cooler plasma and are anchored by magnetic field structure, to the Sun’s surface in the photosphere. So I’ve setup the LuntLS100 this time with a Player One Saturn-M SQR camera which is the perfect combination for this type of full disc images. The photo was captured from Dark Sky® Alqueva territory, in Portugal at UT13h53m.
PT: No passado dia 31 de Julho de 2023, foi possível observar e registar um enorme filamento visível no centro do disco solar. À primeira vista este filamento extendia-se por cerca de quarto do diâmetro solar, o que provavelmente indica um tamanho de cerca de 370.000 km ou 29x o tamanho do nosso planeta Terra. Os filamentos solares são nuvens de gás ionizado, ou plasma, visto em contraste acima da cromosfera. Quando um filamento solar é visto perto do limbo solar, ele passa a ser designado de “proeminência” em vez de filamento. As proeminências contêm plasma muito mais frio e são ancoradas pela estrutura do campo magnético, à superfície do Sol, na fotosfera. Para captar esta imagem configurei o LuntLS100 com uma câmara Player One Saturn-M SQR, que é a combinação perfeita para este tipo de imagens de disco completo. A fotografia foi captada a partir do território Dark Sky® Alqueva, em Portugal cerca das UT13h53m.

Under the Nature to Enjoy the Supermoon of 1st August 2023
Sometimes all we need is an excuse to come outside and just being under the nature during nighttime while enjoying a wonderful super moonrise. Supermoons happen when a full moon approximately coincides with the moon’s perigee, or a point in its orbit at which it is closest to Earth. This makes the moon appear larger and brighter than usual. The 1st August 2023 was on of these moments. The single shot was captured in the beautiful landscape of Dark Sky® Alqueva territory, in Portugal.
PT: Às vezes, tudo o que precisamos é de uma desculpa para sair e ficar sob a natureza durante a noite enquanto desfrutamos de um maravilhoso nascer da lua. Superluas acontecem quando uma lua cheia coincide aproximadamente com o perigeu da lua, ou um ponto em sua órbita no qual ela está mais próxima da Terra. Isso faz com que a lua pareça maior e mais brilhante do que o normal. O dia 1 de agosto de 2023 foi um desses momentos. A foto de um disparo único, foi captada numa das românticas paisagens do território Dark Sky® Alqueva, em Portugal.

Solar Time Lapse of an Entire Full Disc Shows Erupitve Prominences and Minor Flares in Motion
On 9th of July 2023, I took my first solar time lapse of an entire full disc of the sun, showing a lot of interesting features in motion, such as eruptive prominences and minor flares visible in the solar chromosphere while the sun is rotating over the course of 3 hours. The time lapse sequence was captured from Dark Sky® Alqueva territory with a Player One Saturn-M SQR camera and a Lunt telescope LS100, generating 3TB of data. The final result is a 5K high resolution solar movie comprising 213 images over the course of about 3h20m, between UT11h40 and UT15h08.
PT: Em 9 de Julho de 2023, fiz o meu primeiro time lapse de um disco solar completo, mostrando muitos pormenores interessantes em movimento, como proeminências eruptivas e pequenas flares visíveis na cromosfera solar enquanto o sol no seu movimento de rotação girou ao longo de 3 horas. A sequência de lapso de tempo foi captada a partir do território do Dark Sky® Alqueva, com uma câmara Player One Saturn-M SQR e um telescópio Lunt LS100, gerando 3 TB de dados. O resultado final é um filme solar de alta resolução 5K composto por 213 imagens ao longo de cerca de 3h20m, entre UT11h40 e UT15h08.

Solar Chromosphere Showing a Vertical Prominence with Delicate Fine Threads
After a tough winter and spring with unstable weather finally the Summer has arrived with daily clear skies and sun, so I could finally make a solar session on June 28, 2023. The image features a nice chromosphere full of spicules visible in the limb with a vertical prominence showing delicate fine threads stuck in the strong magnetic fields. The image was captured at UT12h35 from Dark Sky® Alqueva territory, in Portugal. As we had a bit of dust from Canada, so I was not able to make a time lapse this time.
PT: Após um inverno rigoroso e primavera com clima instável, finalmente o verão chegou com céu limpo e sol todos os dias. A imagem é o resultado de uma sessão solar em 28 de junho de 2023.

Rare View of Markarian’s Chain Immersed in the Reddish Hydrogen Gas of Virgo Cluster
The image features a deep wide-field scene captured at 530mm and comprising 76,5h of total integration exposure (18,5h in RGB + 58h in Ha), showing galaxies at a distance of 48 million light-years away from Earth, where lies the Virgo Cluster. This collection of galaxies located in the constellation of Virgo, forms the heart of the larger Virgo Supercluster from which the Local Group containing our own Milky Way galaxy, belongs. It’s also known that our own Milky Way galaxy has clouds of hydrogen gas within, lying between us and the Virgo cluster. The image shows more 833 galaxies visible and identified in the annotated version below, and immersed in some of these hydrogen-alpha clouds, while mixed with the clouds contained in the cluster itself. This region is also know as Markarian’s Chain, which includes the gigantic elliptical galaxy M87, the enormous elliptical galaxy M86 and M84, as well as the colorful galaxy M88. The image was captured from Dark Sky® Alqueva Official Observatory, in Portugal, over the course of 17 nights between February and May 2023.

Esta coleção de galáxias localizada na constelação de Virgem, forma o coração do maior superaglomerado de Virgem, do qual pertence o Grupo Local que contém a nossa própria galáxia, a Via Láctea. É sabido que a Via Láctea contém nuvens de gás hidrogénio, situadas entre nós e o aglomerado de Virgem. A imagem mostra 833 galáxias visíveis e identificadas na versão anotada abaixo, e imersas em algumas dessas nuvens de hidrogénio-alfa, misturadas com as nuvens contidas no próprio aglomerado. Esta região conhecida como a Cadeia de Markarian inclui a gigantesca galáxia elíptica M87, a enorme galáxia elíptica M86 e M84 , bem como alguma mais coloridas de onde se destaca a M88.

Solar Chromosphere Shows a Swirling Prominence Near Active Region 13327
After a few weeks of unstable weather with clouds and rain – very unusual for this time of the year – I could finally make a short solar session on June 5, 2023. The image features an eruptive prominence swirling near the Active Region 13327 and below, a large filament hovering over he chromosphere, captured at UT11h20 from Dark Sky® Alqueva territory, in Portugal. As the low dense clouds were passing by all the time, I was not able to make a time lapse. Let’s hope for better conditions in the upcoming days.

Solar Photagraphy with the New Saturn-M SQR Camera from Player One Astronomy
A first light on solar imaging of my newest Saturn-M SQR camera from Player One Astronomy. With a large square sensor of 9MP (1”) it gives a great field of view and much larger resolution, specially useful for producing mosaics or full discs of the Sun in a one single run. On last May 4, 2023 I captured this first light on a very unstable and cloudy day with average to bad seeing conditions and even though the results seems pretty promising, don’t you think? First image was at 10bit mode and second and third images including the black and white version, on 14bit mode. Both has a huge dynamic range but what most impressed me was the fact that I don’t even needed to adjust the tilt plate as it comes from factory, because the image is completely clear, any kind of newton rings visible and non-amp-glow, which gives a perfect clear background.

PT: Uma “primeira luz” da minha mais recente câmara Saturn-M SQR da Player One Astronomy, em fotografia Solar. Com um sensor grande quadrado de 9MP (1”) oferece um largo campo de visão e resolução muito maior, especialmente útil para produzir mosaicos ou discos completos do Sol em uma única sequência. No passado dia 4 de maio de 2023 captei esta primeira luz num dia de atmosfera muito instável e com núvens altas em condições de seeings “médio a mau” e apesar disso os resultados parecerem bastante promissores. Na primeira imagem a câmara estava no modo de 10 Bits e na segunda e terceira imagens, incluindo a versão a preto e branco, no modo de 14 Bits. Ambas revelam uma faixa dinâmica enorme mas o que mais me impressionou, foi o facto de nem precisar de fazer qualquer ajuste na placa de inclinação tal como vem de fábrica, pois a imagem estava totalmente nítida, sem qualquer tipo de anéis de newton visíveis e sem qualquer amp-glow, o que permite um fundo limpo e perfeito. Obrigado Player-One-Astronomy pelo apoio constante, sem dúvida uma câmara planetária com um potencial enorme também extensível ao Sol. Para mais detalhes e um BTS video, visite o story to meu IG .

Rare RED Aurora Display “SAR arc” over Dark Sky® Alqueva Observatory in Portugal on 24th April 2023
After checking many elements with so many coincidences I have now almost 99,9% certain that two nights ago, from 23th to 24th April, when I was over night at the official Observatory of Dark Sky® Alqueva, in Cumeada village, Portugal, capturing my latest deep sky target in a region of the sky full of galaxies known as Markarian’s Chain, I captured the rare moment of a red aurora borealis display glowing over Alqueva, as low as 38º latitude. It happened during the strong burst of activity with a severe magnetic storm reaching a geomagnetic K-index level of 8 between 00h45 and 02h15 (local time +1UT), and then decreasing to a Level k5. I had one of my cameras pointing to west region on a 300mm lens, covering a short field of view. We had a dark starry night, the sky was clear as shown on radar images. Our SQM system at the Observatory was registering the peak measurement of the red glowing light exactly at the same time that I had it visible on my images and the report from Spaceweather alert. Unfortunately I was too tired after a few consecutive nights shooting and was napping a bit between tasks and while my telescopes were working. I didn’t had my fish-eye all sky lens with me, so I had installed only one extra camera with a wide angle, which was pointing to the Milky Way – opposite direction – and started around 2AM when the level decreased suddenly, being registered only at the beginning of the time lapse. But fortunately the close-up deepsky sequence that covers the galaxy field, was showing at the end of the video an incredible red display which last for about 1h. In a question of a few minutes all the sky was fulfilled by an intense red glow coming apparently from “nowhere”, which impels me to believe that this could only be the result of an extreme aurora activity that was visible from all over northern Europe. My friend and TWAN colleague Alan Dyer pointed me to most plausible cause, an even rare type of auroras called SAR arc (Stable Auroral Red) arcs which were only discovered in 1956. Alan mentioned that “in the northern hemisphere, SARs occur south of the main aurora, and would be seen before any aurora itself appears at lower latitudes. They are almost always sub-visual but cameras pick them up easily”. I never saw something like that in my life, and it was not visible with naked-eye, I only noticed after being notified by Spaceweather alerts about the undergoing storm, and after checking if my deepsky camera was focused, but I remember to look up and think on that “weird reddish” light visible on my lcd screen, and even checked if the white balance was ok, but everything was set up properly as expected. Finally, I looked up to visually confirme if the sky was clean, and it was totally clear. Normally from Alqueva, I usual get green airglow on my photos, as red airglow is normally well seen in high altitude places, like Atacama or La Palma, and is indeed faint comparing to the level of brightness I get on histogram. We have confirmed and radar images shows that the sky was clear too, but I even checked the images from two nights before when I was capturing the same region of the sky but had a few high clouds and the appearance on the image is completely different, the image tends to be more pale white and faint galaxies simply vanish while stars shows a diffuse halo or a glow around them. And during the red aurora display the galaxies were still sharp as before and keep revealing the faint dusty oblong shape. Plus after checking Spaceweather website, I saw that an NLC camera located in Southern Spain (37ºN) captured the Northern Lights too, as well in Calar Alto Observatory.
Conclusion, I think that 24th April 2023 is probably an historic date and special moment for me, as the last confirmed reports about auroras in Portugal were from 85 years ago, on 25th de January 1938, and 66 years ago, on 21th January 1957 according to same archive news about this event, and none of them were about “SAR arc”.
The mosaic above shows single shot images from the time lapse sequence, regarding the wide field camera, and images from the left telescope lens. Centered reddish images was related with the middle of the most intense display around 01h38 (local time, with DST active is +1hUT) | PT: O mosaico acima mostra as imagens de disparo único a apartir da sequência time lapse, em relativas à câmara de grane campo e imagens do telescópio da esquerda a 300mm. A imagem avermelhada central é relativa ao meio do evento quando aintgiu a maior intensidade por volta das 01h38 (hora local, com horário de verão ativo é +1hUT).
PT: Depois de verificar vários elementos e tantas coincidências, tenho agora quase 99,9% de certeza que poderei afirmar sem grande margem para dúvidas que há duas noites atrás, de 23 para 24 de Abril, quando pernoitei no Observatório Oficial do Dark Sky® Alqueva, na vila da Cumeada, Portugal, enquanto captava o meu mais recente objecto de céu profundo em uma região do céu cheia de galáxias conhecida como “Markarian Chain”, captei um raro momento que poderá ficar para a história, de o aparecimento de uma aurora boreal vermelha brilhando sobre os céus do Alqueva, a uma baixa latitude de 38ºN. Aconteceu durante um breve momento de actividade extrema com uma forte tempestade magnética atingindo um nível geomagnético (K-index) de K8 entre 00h45 e 02h15 (hora local portuguesa +1UT), e diminuindo no espaço de uma hora e quase repentinamente, para um nível k5. Eu tinha uma das minhas câmaras apontando para a região sudoeste a cerca de 60º de altura com uma lente de 300 mm, cobrindo um pequeno campo de visão. Tivemos uma noite escura e estrelada, o céu estava límpido como mostram as imagens de radar. O nosso sistema SQM no Observatório que mede em permanência a escuridão do céu, registou a medição de pico da luz vermelha brilhante exactamente ao mesmo tempo em que eu a tinha visível nas minhas imagens e no relatório do alerta Spaceweather. Infelizmente eu estava muito cansado depois de algumas noites consecutivas a fotografar e sem praticamente dormir e estava a dormitar um pouco entre tarefas, enquanto os meus telescópios trabalhavam. Eu não tinha a minha lente olho de peixe de 8mm (all sky) comigo, então instalei apenas uma câmara extra com grande angular, que apontava para a Via Láctea – direcção oposta – e que começou a fotografar por volta das 2 da manhã, quando o nível caiu repentinamente, estando registado apenas no início do time lapse. Mas felizmente, a sequência de céu profundo que cobre o campo da galáxias mostra no final do vídeo uma incrível luz vermelha intensa que durou cerca de 1h. Em questão de minutos todo o céu foi preenchido por um intenso brilho vermelho vindo aparentemente “do nada”, o que me leva a crer que isso só poderia ser resultado da actividade extrema das auroras boreais visível em todo o norte da Europa. O meu amigo e colega do TWAN Alan Dyer indicou-me a causa mais plausível, um tipo ainda mais raro de auroras chamado SAR arc (Stable Auroral Red) que só foi descoberto em 1956. Alan mencionou que “no hemisfério norte, os SARs ocorrem ao sul da aurora principal, e deveriam ser vistos antes que qualquer aurora aparecesse em latitudes mais baixas. Eles são quase sempre subvisuais, mas as câmaras conseguem captá-los facilmente” acrescenta. Eu nunca vi algo assim na minha vida, e não era visível a olho nu, só notei depois de ser avisado pelos alertas do Spaceweather sobre a tempestade em andamento, e depois de verificar se a minha câmara deepsky estava focada, mas recordo-me de olhar para cima e pensar naquela luz “avermelhada estranha” visível no meu lcd, e até verificar se o balanço de brancos estava ok, mas tudo foi configurado correctamente conforme o esperado. Por fim, olhei para cima para confirmar visualmente se o céu estava limpo e estava totalmente limpo. Normalmente do Alqueva, costumo obter airglow verde (luminescência fotoquímica da atmosfera) nas minhas fotos, já que o airglow vermelho é normalmente mais comum em locais de grande altitude, como o Atacama ou La Palma, e é realmente fraco em comparação com o nível de brilho que obtivera no histograma. Confirmámos e as imagens do radar mostram que o céu também estava limpo, mas até verifiquei as imagens de duas noites anteriores, enquanto captava a mesma região do céu mas com algumas nuvens altas visíveis e a aparência na imagem é completamente diferente, a imagem tende a ser mais esbranquiçada e pálida e as galáxias fracas simplesmente desaparecem enquanto as estrelas mostram um halo difuso ao seu redor. Durante a exibição desta rara aurora vermelha, as galáxias continuaram nítidas como antes, a revelar a sua forma oblonga empoeirada e ténue. Além disso, depois de verificar o site do Spaceweather, vi que uma câmera NLC localizada no sul da Espanha (37ºN) também captou as auroras boreais, assim como o Observatório Espanhol de Calar Alto.
Conclusão, penso que o dia 24 de abril de 2023 é provavelmente uma data histórica e um momento especial para mim, pois os últimos relatos confirmados sobre auroras em Portugal datam de há 85 anos, a 25 de janeiro de 1938, e há 66 anos, a 21 de janeiro de 1957, segundo alguns arquivos de notícias sobre este evento, e nenhuma delas foi sobre um “SAR arc”.

Solar Tornado Released into Space in a Time Lapse Captured from Portugal on 20th April 2023
On 20th of April 2023, I noticed that the solar chromosphere was featuring a gigantic prominence, so I prepared my solar telescope to start the photo session as I normally do when we have some interesting activity as well as clear and stable sky at Dark Sky® Alqueva region, in Portugal. After about 1h of images, I noticed that this prominence was growing even more which means that probably something bigger as about to happen and I couldn’t imagine that one of my dreams of capturing a Solar Tornado in motion was about to turn into reality. Due to my position on a terrace, my view at this time of the year is blocked after 4:30 PM, so I only had around 1h20m to keep capturing as much images as I could for a time lapse sequence that could show the evolution of this giant of plasma and the incredible moment when it suddenly lifted off, being released into space. According to Spaceweather.com “unlike tornadoes on Earth, which are shaped by wind, tornadoes on the sun are controlled by magnetism. Solar magnetic fields twist in a furious spiral, dragging clouds of plasma around with them. This particular tornado over-twisted, pinched off, and flew straight away from the sun. The debris will not hit Earth.” Here is the animations from NASA SDO and LASCO-c2 (Cactus CME detection) from this same day, showing the same giant as seen from the probe in Space. It seems that Cactus as detected also a CME or at least the release of this Tornado like if it was a CME. The final result is a 4K high resolution solar movie comprising 290 images over the course of about 2h, between UT13h15 and UT15h07.
PT: No dia 20 de Abril de 2023, notei que a cromosfera solar apresentava uma proeminência gigantesca, então rapidamente me apressei a preparar o meu telescópio solar para iniciar a sessão de fotos como normalmente faço quando temos alguma atividade interessante e céu está limpo e estável na região do Dark Sky® Alqueva, em Portugal. Após cerca de 1h de imagens, notei que a proeminência estava a crescer ainda mais o que significava que provavelmente algo maior estaria para acontecer. Não poderia era imaginar que um dos meus sonhos de captar um Tornado Solar em movimento estava prestes a se tornar realidade. Devido à posição em que estou localizado, a minha visão nesta época do ano é bloqueada depois das 16h30, pelo que só tinha cerca de 1h20m para continuar a captar o máximo de imagens possível para criar a sequência de time lapse que pudesse mostrar a evolução desse gigante de plasma e o incrível momento em que repentinamente ele “se descolou”, sendo lançado vigorosamente para o espaço. De acordo com Spaceweather.com “ao contrário dos tornados na Terra, que são moldados pelo vento, os tornados no sol são controlados pelo magnetismo. Os campos magnéticos solares giram em uma espiral furiosa, arrastando nuvens de plasma com eles. Este foi arrancado e voou direto para longe do sol. Os detritos não atingirão a Terra.” Aqui estão as animações da NASA SDO e LASCO-c2 (detecção de CME do sistema Cactus) deste mesmo dia, mostrando o mesmo gigante visto a partir da sonda no espaço. Parece que o Cactus também detectou um CME ou pelo menos o lançamento deste Tornado como se fosse uma CME. O resultado final é um filme solar de alta resolução 4K composto por 290 imagens ao longo de cerca de 2h, entre UT13h15 e UT15h07.

Gigantic Solar Prominence in Motion from 29th January 2023
Captured on the 29th of January, 2023, from Dark Sky® Alqueva region, Portugal, a high-resolution image and time lapse sequence features the chromosphere activity, revealing a gigantic prominence in motion. It’s possible to see a lot of interesting changes on its shape. The size of this giant is stretching around the sun’s limb for thousands of kilometres being several times larger than our planet Earth. As comparison, it has a width beyond the largest system rings of planet Saturn. We can also notice a lot of fine spicules surrounding the solar disc and a fast eruptive prominence coming out from a sunspot, while the chromosphere itself is showing a slower motion. Conditions were good, so I’ve manage to make a time lapse of about 248 images. The final result is a 4K high resolution solar movie comprising around 1h20 minutes of photos.
PT: Captada a 29 de Janeiro de 2023, na região Dark Sky® Alqueva, Portugal, uma imagem de alta resolução e sequência time lapse mostra a actividade da cromosfera, revelando uma gigantesca proeminência em movimento. É possível ver muitas mudanças interessantes em sua forma. O tamanho deste gigante se estende ao redor do limbo solar por milhares de quilómetros. Como comparação, a sua largura poderia ir para além do maior sistema de anéis de Saturno. Também podemos notar muitas espículas finas ao redor do disco solar e uma rápida proeminência eruptiva saindo de uma pequena mancha solar, enquanto a própria cromosfera mostra um movimento mais lento. As condições eram boas, por isso foi possível registar um time lapse de cerca de 248 imagens. O resultado final é um filme solar de alta resolução 4K com cerca de 1h20 minutos de fotos.

Solar Prominence Arching in Motion – Photos and Time Lapse
Captured on the 25th of January, 2023, from Dark Sky® Alqueva region, Portugal, a high-resolution image and time lapse sequence features the chromosphere activity, revealing a an arching prominence trapped by magnetic strong forces. It’s possible to see a lot of interesting changes on its shape and a fast eruptive swirling below on the sun’s limb. We can also notice a lot of fine spicules surrounding the solar disc, while the chromosphere itself shows a slower motion. Conditions were good, so I’ve manage to make a time lapse of about 383 images. The final result is a 4K high resolution solar movie comprising around 2h20 minutes of photos.
PT: Captada a 25 de Janeiro de 2023, na região Dark Sky® Alqueva, Portugal, uma imagem de alta resolução e sequência time lapse mostra a actividade da cromosfera, revelando uma proeminência arqueada presa pelos fortes campos magnéticas. É possível ver muitas mudanças interessantes na sua forma e um rápido redemoinho eruptivo na região inferior do limbo solar. Também podemos notar muitas espículas finas ao redor do disco solar, enquanto a própria cromosfera mostra um movimento mais lento. As condições eram boas, por isso foi possível registar um time lapse de cerca de 383 imagens. O resultado final é um filme solar de alta resolução 4K com cerca de 2h22 minutos de fotos.

Pairing with Jupiter and Venus in a Romantic Conjunction Scene
Me and my wife Apolónia decided to join the sky pairing yesterday night, for a nice twilight scene while planets Venus and Jupiter were still close in a romantic conjunction illuminated by the moonlight as seen from Alentejo fields inside Dark Sky® Alqueva territory, in Portugal. Even having a little haze due to high thin clouds, I used a fog filter in front of the lens to help distinguish the little shining guys.

Mesmo tendo um pouco de neblina devido às nuvens altas e finas, usei um filtro difusor na frente da lente para ajudar a destacar os dois planetas brilhantes.

Earth Shadow – The Beauty of a Total Lunar Eclipse in Motion
A video time lapse in 4K shows what is the deepest feeling of experiencing the incredible moment when the moon passes through the Earth’s shadow, giving the natural satellite a blood-red hue during a total lunar eclipse. The stars around the moon are again visible as the light of the moon drops drastically, giving rise to a unique moment of seeing the mesmerising presence of the Milky Way but at the same time, the shinning moon reflecting a low reddish light for being immersed inside the Umbra of the Earth shadow. The movie also intend to reveal the emotional feeling and ambience which surround us during this celestial event, when we are under the real darkness of a pristine starry sky like Mértola, in Dark Sky® Alqueva territory, Portugal. All the images were captured during the Total Lunar Eclipse of 16th May, 2022. For being near the closest point to our planet Earth, this Moon was also called a “Super Blood Moon”. According to timeanddate.com next Lunar Eclipse it will happen in 2023, on 5-6 May and will be a Penumbral Lunar Eclipse visible in Europe, Asia, Australia, Africa, Pacific, Atlantic, Indian Ocean and Antarctica. Close to the end of the year, on 28-29 October 2023, it wil be visible a Partial Lunar Eclipse, seen from Europe, Asia, Australia, Africa, North America, Much of South America, Pacific, Atlantic, Indian Ocean, Arctic, Antarctica.
PT: O vídeo time lapse em 4K mostra qual é a sensação mais profunda de experimentar o momento incrível em que a lua passa pela sombra da Terra, dando ao satélite natural um tom vermelho-sangue durante um eclipse lunar total. As estrelas ao redor da lua são novamente visíveis à medida que a luz da lua cai drasticamente, dando origem a um momento único, o de poder apreciar a presença hipnotizante da Via Láctea, e ao mesmo tempo, a lua brilhando e refletindo uma luz avermelhada por estar imersa na Umbra da sombra da Terra. O filme também pretende revelar de alugma forma o forte sentimento e emoção que se experiencia no ambiente que nos rodeia durante este evento celestial, quando estamos sob a verdadeira escuridão de um céu pristino estrelado, como o de Mértola, no território Dark Sky® Alqueva, Portugal. Todas as imagens foram captadas durante o Eclipse Lunar Total de 16 de maio de 2022. Por estar perto do ponto mais próximo do nosso planeta Terra, a lua também foi apelidada de “Super Luar de Sangue”. De acordo com timeanddate.com o próximo Eclipse Lunar acontecerá em 2023, de 5 para 6 de maio e será um Eclipse Lunar Penumbral visível na Europa, Ásia, Austrália, África, Pacífico, Atlântico, Oceano Índico e Antártica.

Comet ZTF and Mars Shinning close to Hyades and Pleiades Immersed in the Colorful Dusty Field of Taurus
A wide field view of the winter sky shows a duet of open clusters known as Hyades and Pleiades, involved in the faint dust from Taurus molecular cloud. Comet c/2022 E3 (ZTF) and planet Mars also joined the scene, while being visible in this region of the sky on February 13, 2023. The close-up image of Mars and Comet ZTF was taken from Dark Sky® Alqueva official osbervatory in Portugal, on this date with a 300mm lens and it was later rescaled and star aligned to perfectly match on the background deep field scene I had previously acquired and processed in 2020, which comprises 5h of long exposure integration taken from the same place with a 105mm lens to reveal the faintest dust of this colorful region of the winter sky. For that particular reason, the field unfortunately doesn’t cover entirely the area where is located planet Mars.
PT: Um amplo campo de visão revela um dueto de aglomerados abertos conhecidos como Híades e Pleiades, envolvidos na ténue poeira da nuvem molecular do Touro. O cometa c/2022 E3 (ZTF) e o planeta Marte também entraram em cena, sendo visíveis nesta região do céu a 13 de Fevereiro de 2023. A imagem em close-up de Marte e do cometa ZTF foi captada nesta data a partir do Obervatório Oficial do Dark Sky® Alqueva, na Cumeada, com uma objectiva de 300 mm e posteriormente foi redimensionada e alinhada às estrelas para ser combinada com a imagem de fundo adquirida e processada previamente em 2020 a partir do mesmo local, e que compreende uma integração total de 5h de exposição, captadas com uma lente de 105 mm para assim poder revelar a poeira mais subtil e fraca dessa região colorida do céu de inverno. Por esse motivo particular, o campo infelizmente não cobre totalmente a área onde está localizado o planeta Marte.

Comet ZTF and Planet Mars Shinning in the Faint Dust of Taurus Molecular Cloud
The image shows a wide view of Comet c/2022 E3 (ZTF) on February 13, 2023, while being in a close encounter with Planet Mars in Taurus constellation. Still featuring the wonderful greenish coma from glowing carbon gas, a dust and yet visible long faint ion tail, the comet was shining between the dust of dark nebulas from the Taurus molecular cloud.

One Month of ZTF – The Green Comet in Motion Revealed in a 4k Time Lapse Video
A long video time lapse sequence comprising 5 nights of images spread over the course of January month 2023 (Jan. 3, 18, 22, 24 and 31) shows in a 4K resolution the motion of the so called “Green Comet” c/2022 E3 (ZTF) while travelling across the night sky over Dark Sky® Alqueva official observatory, in Cumeada village, Portugal. The video reveals key moments of its incredible activity starting to feature a wonderful greenish coma from glowing carbon gas and a white dust tail, until the main Disconnection Event happened on January 18, revealing a piece of the plasma tail being uprooted from the comet’s head, and then carried away by the solar wind. But ZTF didn’t stop to surprise, and also start to reveal a rare anti-tail which gradually changed the angle position while our planet Earth was crossing the orbital plane of the Comet. Meanwhile the main Ion tail was split in two blueish ion tails visible on Jan. 24. On January 31, the Comet was close to reach the maximum approach to Earth, and the anti-tail was largely scattered in the white dust revealing a dispersion and a low angle before start to vanish in the days ahead. The comet was photographed late in the night in all the sessions, starting at a distance of 146.1 million Km on Jan. 3, until being very close to our planet on Jan. 31 at a distance of only 43.1 million Km. The long distance traveller was moving fast against the background starry sky and the video also shows a few rapid greenish meteors crossing the field of view, as well as the moment when ZTF was crossing close to a few galaxies. I did a huge effort to create this movie, capturing and processing almost 1TB of data in a total of 10h comprised in 521 final images, to try to show the path of this wonderful visitor in the mesmerising moments of rare beauty provided to us by ZTF before it starts to fade way in a long journey of 50,000 years immersed in the deepest cold and darkness of the Solar System.
PT: Uma longa sequência de vídeo time lapse compreendendo 5 noites de imagens espalhadas ao longo do mês de Janeiro de 2023 (3, 18, 22, 24 e 31 de Janeiro) mostra em resolução 4K o movimento do chamado “Cometa Verde” c/2022 E3 (ZTF) enquanto viajou pelos céus do Observatório Oficial Dark Sky® Alqueva, na vila da Cumeada, Reguengos, Portugal. O vídeo revela os principais momentos de sua incrível passagem e actividade, começando por apresentar um maravilhoso coma esverdeado proveniente do brilho do gás carbono, e uma cauda de poeira branca, até que o principal evento de desconexão aconteceu em 18 de janeiro, revelando um pedaço da cauda de plasma a ser arrancado da cabeça do cometa e depois levado para fora pelo vento solar. Mas o ZTF não parou de surpreender, tendo começado a revelar uma rara anti-cauda que gradualmente mudou o ângulo da sua posição enquanto nosso planeta Terra cruzava o plano orbital do cometa. Enquanto isso, a cauda principal de iões dividiu-se em duas caudas de iões azuladas visíveis a 24 de Janeiro. Em 31 de Janeiro, o cometa estava perto de atingir a máxima aproximação à Terra, e a anticauda apresentou uma grande dispersão na poeira branca revelando um ângulo baixo, antes de começar a desaparecer nos dias seguintes. O cometa foi fotografado no final da noite em todas as sessões, partindo de uma distância de 146,1 milhões de Km no dia 3 de Janeiro, até estar bem próximo do nosso planeta Terra no dia 31 de Janeiro com uma distância de apenas 43,1 milhões de Km. O viajante de longa distância movia-se rapidamente contra o céu estrelado de fundo e o vídeo também mostra alguns meteoros esverdeados rápidos cruzando o campo de visão, bem como o momento em que o ZTF passou “perto” de algumas galáxias. Fiz um esforço enorme para criar este filme, captando e processando quase 1TB de dados num total de 10h compostas por 521 imagens finais, para tentar mostrar o percurso deste maravilhoso visitante através dos momentos hipnotizantes de rara beleza que nos proporciona o ZTF, antes de começar a desaparecer em uma longa jornada de 50.000 anos, onde irá imergir no mais profunda escuridão gélida do Sistema Solar.

A Last Charm of Comet ZTF While Reaching the Closest Point to our Planet Earth
The image shows a close-up view of Comet c/2022 E3 (ZTF) on January 31, 2023, just a few hours before it reach the maximum approach to our Planet Earth. Still featuring the wonderful greenish-blue coma from glowing carbon gas, the rare anti-tail is now pointing towards down due the actual position in the orbital plane. The comet is now showing almost a single distinct ion tail. This was perhaps my last image of this beauty due to the full moon presence acting as a natural source of light pollution and the fact that from now on, the comet it will decrease in brightness as is starts to fade way in a long journey of 50,000 years immersed in the deepest cold and darkness of the Solar System. This cosmic portrait also reveals dozens of galaxies surrounding the Comet dust. Captured late in the night at a distance of 43.1 million Km from Dark Sky® Alqueva Observatory in Portugal. ZTF was located in the constellation of Camelopardalis, showing a faint visual magnitude of +5.4.
PT: A imagem revela um close-up do Cometa c/2022 E3 (ZTF) na noite de 31 de janeiro de 2023, apenas a algumas horas antes de atingir a máxima aproximação ao Planeta Terra. Ainda exibindo um elegante coma azul-esverdeado proveniente do brilho do gás carbono, a rara anti-cauda está agora apontando na direcção inferior devido à sua posição no plano orbital. O cometa neste momento mostra quase uma única cauda distincta de iões. Esta foi talvez a minha última imagem desta beleza devido à presença da lua cheia actuando como uma fonte natural de poluição luminosa e ao facto de que a partir de agora, o cometa diminuirá gradualmente de brilho à medida que começa a desaparecer em uma longa jornada de 50.000 anos, onde irá imergir no mais profunda escuridão gélida do Sistema Solar. Este retrato cósmico também revela dezenas de galáxias em torno da poeira que circunda o Cometa. Captado no final da noite e a uma distância de 43,1 milhões de Km do Observatório Dark Sky® Alqueva em Portugal. ZTF estava localizado na constelação de Camelopardalis, mostrando uma fraca magnitude visual de +5,4.

Comet ZTF Featuring Two Ion Tails While Crossing in Front of a Galaxy in a Colorful Starfield
The image shows a close-up view of Comet c/2022 E3 (ZTF) during 24th January 2023. Besides the wonderful greenish coma from glowing carbon gas the image reveals a rare anti-tail due the fact that planet Earth was crossed the orbital plane of Comet ZTF showing the tail in perspective and immersed in a colorful starfield. One thing I noticed from the previews nights, is the low angle of the frontal tail compared to the images I made on 22th Janurary, as it now shows a slightly change in the angle. The comet if also featuring two distinct bluish ion tails and the white dust tail on the image, is crossing in front of a background galaxy. The comet was photographed late in the night at a distance of 59.8 million Km from Dark Sky® Alqueva Observatory in Portugal. This long distance traveller not seen in 50,000 years, is moving fast against the background starry sky, and that night it was located close to the star Edasich, from Draco constellation, showing a faint visual magnitude of +6.0. On 1st February the Comet it will be in the closest point to our planet and eventually until then, it could reach a naked eye magnitude.
PT: A imagem revela um close-up do Cometa c/2022 E3 (ZTF) durante a noite de 24 de Janeiro de 2023. Além de apresentar um maravilhoso coma esverdeada proveniente do brilho do gás carbono, a imagem revela uma rara anti-cauda devido ao facto do planeta Terra ter cruzado o plano orbital do Cometa ZTF mostrando assim a cauda em perspectiva e imersa em um campo estelar colorido. Um pormenor que notei em relação às noites anteriores, é o baixo ângulo da cauda frontal (anti-cauda) em comparação com as imagens que fiz na noite de 22 de Janeiro, pois agora mostra uma pequena mudança nesse ângulo. O cometa, também apresenta duas caudas de iões azuladas e distintas e a cauda de poeira branca, na imagem, esta a cruzar-se em frente a uma galáxia visível em pano de fundo. O cometa foi fotografado no final da noite a uma distância de 59.8 milhões de Km a partir do Observatório Dark Sky® Alqueva em Portugal. Este viajante longínquo que não se avistava há cerca de 50.000 anos, move-se muito rapidamente contra o fundo do céu estrelado, e naquela noite estava localizado próximo à constelação do Dragão, mostrando uma fraca magnitude visual de +6.0. A 1 de Fevereiro o cometa estará no ponto mais próximo do nosso planeta e eventualmente até então poderá atingir uma magnitude visível a olho nu .

Disconnection of the Comet C/2022 E3 ZTF in Motion Revealed in a 4k Time Lapse Video
A video time lapse sequence comprising around 3h30 minutes of images shows in a 4K resolution the moment when the Disconnection Event happened in the Comet c/2022 E3 (ZTF) during the night of 19th January 2023, revealing a piece of the plasma tail being uprooted from the comet’s head, and then carried away by the solar wind. The movie also features the wonderful greenish coma from glowing carbon gas and rare anti-tail. The comet was photographed late in the night at a distance of 79 million Km from Dark Sky® Alqueva Observatory in Portugal, during the last three hours and half before starts the astronomical twilight. This long distance traveller not seen in 50,000 years, was moving fast against the background starry sky while a few rapid greenish meteors were crossing the field of view too. That night, ZTF was located between constellations of Hercules, Corona Borealis and Bootes, showing a faint visual magnitude of +6.6. Although on 1st February the Comet it will be in the closest point to our planet and eventually until then could reach a naked eye magnitude, but this kind of objects are pretty unpredictable and we never know what surprise is waiting for us.

PT: Uma sequência de vídeo time lapse que compreende 3h30 minutos de imagens em resolução 4K, mostra o momento em que o Evento de Desconexão aconteceu no Cometa c/2022 E3 (ZTF) durante a noite de 19 de Janeiro de 2023, revelando um pedaço da cauda de plasma a ser arrancado da cabeça do cometa e depois levado para fora pelo vento solar. O filme também mostra o maravilhoso coma esverdeado proveniente do brilho do gás carbono e uma rara anti-cauda. O cometa foi fotografado no final da noite a uma distância de 79 milhões de Km do Observatório Oficial do Dark Sky® Alqueva em Portugal, durante as últimas três horas e meia da noite até ao início do crepúsculo astronómico. Este viajante de longa distância que não se avistava há cerca de 50.000 anos, move-se muito rapidamente contra o fundo do céu estrelado enquanto alguns meteoros rápidos esverdeados também cruzavam o campo de visão. Naquela noite o ZTF estava localizado entre as constelações de Hercules, Coroa Boreal e Boieiro, mostrando uma fraca magnitude visual de +6,6. Embora a 1 de Fevereiro o cometa esteja no ponto mais próximo do nosso planeta e eventualmente até então possa atingir uma magnitude visível a olho nu, este tipo de objectos é bastante imprevisível e nunca sabemos que surpresa nos reserva.

Comet c/2022 E3 ZTF Featuring a Rare Anti-Tail During a Disconnection Event
The image shows a close-up view of Comet c/2022 E3 (ZTF) during 19th January 2023.

A Tree, a Man and the Mesmerising Presence of our Cosmic Home
Feeling blessed to live so close to Dark Sky® Alqueva reserve where I can easily reach places like this, places that I love and where pristine skies are still possible to see. On this particular night taken during one of my workshops at the end of Summer, the airglow was visible and painted the background sky with greenish hues. In front of the airglow, a few high clouds announce the proximity of Winter, while Milky Way is straight up to the Zenith, the core is getting low and close to the horizon and in a few weeks no longer will be visible until next Summer. In the foreground, my silhouette as a stargazer stands at the side of a lonely wonderful tree which rises leafy before the majesty presence of our cosmic home.
PT: Sinto-me abençoada por viver tão perto do Dark Sky® Alqueva onde posso chegar facilmente a lugares como este, lugares que me apaixonam e onde ainda é possível disfrutar de um céu pristino. Nesta noite em particular, que decorreu durante um dos meus workshops no final do verão, o airglow era visível e pintava o céu de fundo com tons esverdeados. Diante do airglow, algumas nuvens altas anunciam a proximidade do Inverno, enquanto a Via Láctea sobe em direcção ao zénite, o núcleo vai ficando baixo e próximo ao horizonte e em algumas semanas não será mais visível até ao próximo Verão. Em primeiro plano, está a minha silhueta enquanto observador de estrelas, lado a lado com uma árvore solitária mas que se ergue frondosa diante a grandeza desta paisagem cósmica.
