Description

I was planning to capture this target in HOO palette, but after collecting 2 hours of OIII data I realised that my processing skills are not good enough/sky quality is too low (bortle 7 near center of mid-sized polish city)/OIII needs a lot of integration time to pop up, so I decided to abandon it and stick to colorized version of Ha only. Maybe next year I will collect SII and add to this data, but I'm not fixated on this considering my limited amount of time which I can give to the hobby.

This is how looks starless version of OIII, 2h integration time, calibrated and autostretched:

Update 21.09.2024:
7h of Sii collected which allowed me to create SHO version.
