The part that always amazes me about the Andromeda Galaxy is that it is close to the same size as moon when you look at them from earth. Andromeda is really big. It’s just not as bright as the moon. Another extraordinary piece of the sky. I love what you can see of space using a camera.
And, at 2.5 million ly away it's the closest galaxy to us in the universe!

I decided to emphasize the colors in this version. I used the Archsinh stretch that brings out colors and used the curves and color saturation tools. Certainly this is the most colorful version of the Andromeda Galaxy that I have ever done.
