Concentrating on the ionasation front.
I did try adding some SII data but the image had a purple gradient. I’ll have to investigate why.
Nice bicolour image.
Ha 5 minute and 10 minutes sub frames for OIII. Increased OIII exposure times to offset strong Ha component. All at 2Ă—2 binning.
HA/OIII/OIII image with 8 hours and 10 minutes of data. 48 x 5min Ha & 25 x 10min Oiii.
