A second good Red Friday evening, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "The Windmill and the Star Trails." I do appreciate the creative photographer. The Canary Islands must be true fertile ground. This composite image, made up of 39 exposures each 25 seconds long, frames the heavens against an old windmill aligned with Polar North. Definitely well done. Can you pick out the Andromeda Galaxy?

"Explanation: Stars can't turn these old wooden arms, but it does look like they might in this scene from a rotating planet. The well-composed night skyscape was recorded from Garafia, a municipality on the island of La Palma, Canary Islands, planet Earth. The center of the once working windmill, retired since 1953, is lined-up with the north celestial pole, the planet's rotation axis projected on to the northern sky. From a camera fixed to a tripod, the star trails are a reflection of the planet's rotation traced in a digital composite of 39 sequential exposures each 25 seconds long. Brought out by highlighting the final exposure in the sequence, the stars themselves appear at the ends of their short concentric arcs. A faint band of winter's Milky Way and even a diffuse glow from our neighboring Andromeda Galaxy also shine in the night. "

I don't know much about astronomy, but that picture is spectacular. It's amazing what a person can do with time-lapse photography and composite images.
