It's taken using a Dwarflab 3, so obviously one can argue about how much I actually did myself :p

Yeah, it's the Andromeda Galaxy. I planned on just trying it out, not expecting it to work so well in the area in front of my apartment (lots of light pollution) - but it worked well enough so I stood there two hours. I would have loved to expose even longer, but my feet were already quite dead at that point.
