Swindon, Wiltshire. UK

GSO 8″ Richey-Chretien Optical tube, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik filters.

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 2×2 binning.

HA/OIII/OIII image with 8 hours and 10 minutes of data. 48 x 5min Ha & 25 x 10min Oiii.
