From "PRO DATASETS" from Telescope Live.
It is an HSO image from 13 exposures (Hx8, Sx3, Ox2) for 300" each = 1h 5m
I can't give up on "traditional" colors, so
I assigned the HSO images to the RGB channels:
PixInsight : Dynamic narrowband combinations with PixelMath:
R = (Oiii^~Oiii)*Sii + ~(Oiii^~Oiii)*Ha
G = ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~
(Oiii*Ha))*Oiii
B = Oiii
Cropped, resampled
Heart Nebula
