This is my take after about 9 hours of total exposure time.
William GT81, 0.8 flattener, OAG w/ 120mm mini for guide, ZWO EFW with Chroma Ha, OIII, and SII, ASI 6200mm. All on a GEM 28 using an ASI AIR Pro for control software.
I think I used an HSO palette for this. Processed with APP, Photoshop, and Starnet++.
