Startrail in the Sunset

After the sunset, the sky takes fantastic colors and warm tones full of life. While waiting for the night fall to become the visible clouds of dust and gas in our galaxy, I registered a startrail a little different than usual, where are clearly distinguishable the different colors of different stars. In astronomy, the yellow/orange stars are more cold than the white/blue stars. A curiosity, is that the track nearest the rock and water, in the left area of the image, refers to the planet Mars, who was also visible when I started the session. In the atlantic ocean, the waves dragged the foam that was drawing the sand and reflecting a magnificent sky full of light and color .
