The shot is cropped a little to center Andromeda but it's near full frame. Andromeda is HUGE in the sky and can be seen with binoculars.

^This is what TB post in another thread about the same pic.

I'm gonna get my binoculars out tonight and try to find it!
Here's how to find it... http://earthsky.org/?p=2848

Cassiopeia is easy to find and once you find it, Andromeda is easy.
