Photographing the Andromeda Galaxy

That blurry smudge in the middle of my photo? I think…I think…that’s the Andromeda Galaxy. It’s the most distant object humans can see with their unaided eyes. Here, we’re aided, zoomed in quite a lot. There’s blur due to camera shake, unfortunately, or is an 8-second exposure too much to not get star trails with a 150 mm zoom…

If it’s not Andromeda I’d like to know what it actually is as it was definitely a barely visible smudge in the sky away from the big “arrowhead” of Cassiopeia and in a line from Mirach and Mu Andromedae in the constellation of Pegasus.
