Looks like it is indeed Andromeda (per UT Austin, "I'm basically 100% sure it's Andromeda"). Yet, based on what I've read, I'm surprised it is so clear and bright in the photo. Surprised too the faint outer reaches of Andromeda show up like a fading cloud around the center without much blurring on a long-exposure picture... Doesn't seem like there would be enough sensitivity in the camera sensor to capture that so delicately on a long-exposure shot... However, the UT Austin Astronomy Dept was equally excited by another item in the picture -- "The Double Cluster of Perseus (Caldwell 14)". I highlighted it with a blue circle in the attached photo.... They indicated it's not easy to get a picture of the double cluster with both clusters being distinct and separated... Who knew? I just put the camera on a tripod, took some guesses at exposure settings, and pushed the button... on a night that wasn't especially clear.... Photo by Marty McCasland.
