Description

Under full moon and with a light setup, I wanted to "catch" Collinder 399 "Coathanger" with my 200mm lens Pentax (but without GOTO...). So I missed it a bit.

Big gradient caused by full moon...

SIRIL 0.99.10.1 stacking drizzle or no drizzle...bad results, however 6 hours total exposure (I kept only near 5 hours) with a low iso choice.

Version B with SEQUATOR stacking...a bit less bad image.
