The third largest galaxy in our local group (after Andromeda and our own Milky Way), located 3 million light-years away. (How many '3's are associated with it? :-)

Somewhat disappointed with this effort. I started with 60 minutes of lights but threw half out due to flexure artifacts. Somehow my mount has developed a lot of play and backlash in DEC particularly and it's taking a big toll. Was going to work on getting an autoguider set up, but now I think the first order of business is to address whatever problem the mount is having. Happy to have another couple of months to try to this target again.
