Also a small caliber, on a double-barrel setup, you have to capture the sky, we can always process it later. The result of one night.
The guide scope was capturing this same object in close-up, with tracking errors and frame adjustments, but on this one, I just let a series run, then had to discard frames with tracking errors and adjustments—out of 140, 115 remained.
The telescope's focal length is 364mm.

Stacked with drizzle -2.
