My attempt here. Used C.925 Edge HD with OMGA AP26MC Monochrome (IMX571) and Baader F/2 Ha / Oiii 6.5nm filters. Skies are technically Bortle 4 but nearing Bortle 5 as the scope points West. Shot exposure based on 130 (3 minute) Ha @ High Gain, and 130 (3 minute) @ Low Gain subs. Kinda of forgot to reset the Oiii to High Gain, but is what it is and weather and moonlight uncooperative. Shot is processed in PixInsight with Drizzle 2X, and stacking the Oiii (~2.5X), and then using pixelmath to merge into HOO using dynamic formula.... Not completely thrilled with halo around the brightest star and might try some different process of histogram, curve transformation to tame this a bit... O

Thanks.... Hoping to get some broadband RGB, perhaps L and using this data to cleanup the stars (i.e. replace the Ha/Oiii data used for the stars). Looks like Monday night will be clear, so crossing my fingers here....

Was able to get additional data, although not RGBL due to moon.... I think it looks better although stars still a bit wonky....
