Description

Captured over two nights [4/3 & 4/5], due to low elevation this time of year. I believe the horizontal, thick crescent in the lower left quadrant near the left edge is IC 444, which is listed at the top as an included object, but is not so labeled.

This was my first real capture with 900s subs, which worked well on this target. I tested 900s on another target [Gum1/Seagull] and it was clearly too much with my system.
