I was literally about to go to the store (I'm wearing my coat), but then I saw that the computer was done stacking the images of Andromeda I got last night and I got absorbed with inspecting the results. I'm very happy, even if it's a relatively easy target to get a nice pic from (it's big and bright).
I'm capturing more Ha of M31 tonight so I can hopefully add a little more detail, but here's the WIP so far because it's cool. Will post the finished pic later.
