My longest integration so far and first light for my small TS 70/420 mm triplet. Oiii on this object is very faint, not even barely visible on a single 300" exposure.+
Dates:
Ha: 2020-07-13, 2020-07-20, 2020-08-07
Oiii: 2020-08-20, 2020-08-21
Editing workflow:
Ha:
Crop, DBE, Decon (deringing and pixmath), Denoise (TGV+MMT), MaskedStretch, HT, LHE, Curves, MLT (sharpening and NR), ACDNR
Oiii:
DBE, Decon (Deringing and PM repair), TGVDenoise, HT, LHE, ACDNR, LHE
Combination:
For the color:
Combine Ha and Oiii with:
R: Ha
G: ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii
B: Oiii
For the detail:
Create syn lum with max(Oiii, Ha)
LRGBCombination of the both
Crop out bad non overlapping edges, Curves, EZStarReduction (A. Block Method), MLT (NR), ACDNR, Curves
Downscale to a reasonable size.
