Planetary nebula K1-14 (PK 45+24.1)

This field shows a planetary nebula in Hercules. It's a nebula created by a dying sun, and it has nothing to do with planets.
The saturated vertical lines are blooms - an artifact of the CCD that I cannot yet fix in an acceptable way. I'll experiment with bloom removal approaches, but don't hold your breath - I accepted blooms when I pulled the trigger on the CCD.

Other notes:
A busy night. Polar alignment took me ~1 hour rather than the typical 10 minutes. Thankfully I was able to do it all before complete darkness, so I didn't lose precious time.
Once running, guiding was all over the place. I saw what looked like oscillations in RA and DEC, but I couldn't tell if it was the mount of seeing. As the night progressed, the issue slowly went away and by the time I was taking pictures, all was well. My best guess is that seeing was mediocre. The only other possible cause for this issue would be dangling cables, but I had them all tied down properly. Things improved further once I increased guiding exposures from 2 seconds to 5 seconds.
I bumped up the exposure time to 10 minutes. I deemed this necessary after I critically looked at the M101 frames. The unfortunate consequence of the 10 minute exposures is that the blooms are ever larger than they would be at 8 minutes. You'll have to find a way to be ok with blooms - I know I am.
I used the mirror lock for the first time, and I think I'll use it again in the future. The FWHM of the stars was mostly varying with seeing.
I mooched a lot of views through Vince's 16quot;, which kept me more awake than usual.
Wildlife report: A king snake, a tarantula, mother and baby quail, !!!LOTS!!! of moths (I think I walked in on an orgy), a fox, mosquitoes that were exclusively interested in biting me in the butt (5+ bites, what the hell).
