I can see it'll take a while to come to grips with these narrow band filters. Judging how much of each you need twil be difficult and this one shows the disparity.
All 10minute subs but the S2 is binned x2. Also there is no calibration on this data at all. No darks bias or flats. Somehow, the gain/offset setting on the qhy9 changed and cal files drove the light images negative :(
FS-102 @ F8. QHY9 @ -30C. 12xHa, 8xO3, 8xS2 10minutes each.
Hubble Palette with Ha lum. Cropped a bit due to flip.
