Urban Spider & Fly Nebulae - IC417 & NGC1931

Welcome to my parlor said the spider to the fly. I've added another two hours of data to this one over the last few nights and improved the processing considerably. The shot was taken from my urban driveway with bright, but clear bortle 6-7 skies.

According to the NASA APOD site - Bright clusters and nebulae abound in the ancient northern constellation of Auriga. The region includes the open star cluster M38, emission nebula IC 410 with Tadpoles, Auriga's own Flaming Star Nebula IC 405, and this interesting pair IC 417 and NGC 1931. An imaginative eye toward the expansive IC 417 and diminutive NGC 1931 suggests a cosmic spider and fly. About 10,000 light-years distant, both represent young, open star clusters formed in interstellar clouds and still embedded in glowing hydrogen gas. For scale, the more compact NGC 1931 is about 10 light-years across.

Object IC417,  RA 05:28:07, Dec +34:25:26
Date 16 January, 2021 & April 2022
Exposure 4 hours (16 X 15 minutes)
Conditions Very transparent, very good seeing, high light pollution (Bortle 7)
Gain 100
Camera Zwo ASI2600MC-Pro
Optics Prime focus of a  SkyWatcher Esprit 120 f/7 APO refractor with a focal length of 840 mm
Filter Optolong L-eNhance
Location Bedford, Nova Scotia
Processing This image was captured using Sequence Generator Pro and processed using a split star process entirely in Images Plus. I'm going to have to add some RGB data to this narrow band image to bring out more of the blue throughout the field. Much of the colour other than red was removed by the L-eNhance filter.
