Arp 68 (NGC 7756 & 57)
| Arp 68 is another in
the class Spirals with Small HSB Companions on Arms. The notes mention "many star-like knots
lined up along straight arm". It is a beautiful galaxy and it took
three tries to get an image which did it justice. NGC 7757 is the primary; NGC 7756 is the small galaxy
northwest of the core, hanging down from the north arm.
I thought that I had a meteor trail running from southwest to northeast, just missing the galaxy to the southeast. However, after seeing that it was in images taken several years apart, I realized it was a diffraction spike (or reflection) from 5th magnitude 19 Psc, not quite a degree to the SW.
