NGC 5426/5427 (Arp 271)

This field shows NGC 5427 (lower right, top half), NGC 5426 (lower right, bottom half), and NGC 5468 in the top left. NGC 5426/5427 are connected through some arms which landed it in place 271 of Arp's catalog. Many galaxies lurk in the background.

I apologize for the crammed composition. Again (like in the 4038/4039 image), the star shapes are funky. I'll reprocess this during a full moon.

Other notes:
This was the second session of a two-session week with one mid-week outing. While I did have a third target planned for this particular night, I was dead tired, so I left 'early' - ~3 am.
This particular night was pretty nice. Seeing was excellent, which allowed me to see a shadow transit and a Great Red Spot transit happening on Jupiter at the same time.
During the second half of the night, a Hummingbird hawk-moth was harassing my visual setup.
