Description

SH2-124 is a diffuse, emission nebula in Northern Cygnus. This was my first Narrowband image in Aug 2019 and a harder project than I anticipated due to 9000+ stars in the frame (as detected by PixInsight). Field rotation or coma in the corners was quite noticeable so I cropped the image to about 50%!! after stacking and processed from there. Next time I capture a diffuse nebula I'm going to leave the stars in to avoid over-processing. Its all Ha so it's all red, so I experimented with selective color and settled on what you see.

Hyperstar imaging is pretty fast so I used 12nm filters as recommended by the folks at Starizona.
