The Arp galaxies are fascinating in the many ways these galaxy groupings interact. Arp 94 in Leo doesn't seem to be imaged all that often by amateurs and I'm not sure why. Perhaps it is because of its proximity to Gamma Leonis. Perhaps it is because everyone seems to focus on the much more famous nearby Messier objects such as Messier 65 and 66. Whatever the cause this set of galaxies is certain interesting. This is 23 subs of 10m each binned 1x1 for a total of 3 hour 50 minutes.
Tazer on Cloudy Nights clued me into the really nice annotation capabilities in PI. For some reason, it does miss a few bright PGC galaxies in the field, especially the one above Arp 94.
Finally, I have added two more hours (2 sixty minute subs in Ha binned 1x1) to my image of Sharpless 2-224.
