Description

This supernova remnant nebula is my second expedition into mono-narrowband imaging. I started this with multiple nights from the backyard and finished at a dark sky site. OIII was especially weak, and in the end only the dark-sky Oxygen subs were not rejected. I would have like to have a LOT more OIII subs! Another night perhaps.

On the same dark-sky night I also shot this area with my Redcat 51 with one-shot color and a Optolong L-Ultimate filter. You'll find that nearby in my library.
