Description

Multiple nights imaging 4 hrs from 2017, 2.5 hrs from this year.
2.75hr Ha
2 hr S2
1.75 hr O3
ASI1600 with a mix of gain 139 and 200 and exposure lengths. Cropped about 35% of image due to alignment challenges.

Stacked in DSS with 2x drizzle
Processed in Startools v1.5 with 4x bin.
Removed stars with heal function to create a starless image and overlaid after stretching the SHO portion a little further. Strongly recommend Startools for good results in only an hr or two.
