The Andromeda Galaxy has been one of my favorite pursuits since I started with astrophotography. It took me a while to figure out how to shoot it and each telescope you use reveals different things about the galaxy. I took this photo of Andromeda Friday night using a 14.5 inch RC and full format CCD. Andromeda is still too big to fit completely in this field of view, but I think we are getting about 75% of it. For reference, this is the same setup I used on the blue moon, so yes, Andromeda is bigger than the full moon in the night sky. Its just dimmer and harder to see with the naked eye. Imagine what it would be like to look up in the sky and see something like this.

For comparison purposes, here are some past photos I’ve taken of Andromeda: Andromeda with a FLT 98 wide field telescope and SBIG ST8300 CCD in September 2011, Andromeda with FLT 98 and DSLR Camera in September 2010, the first picture I ever took of Andromeda with a Celestron CPC1100 and DSLR in January 2010 and of course the telescopic Bolide with Andromeda picture from July 2009.
