SH2-54 in Serpens Cauda. Did n earlier version but managed a night recently to get a lot more OIII data. Now 6.5 hours of OIII so was able to really push the colours and contrast.
Scope is the Stellarvue SVR102T at f5.8, camera the ASI1600MM Pro, Astrodon NB filters all on an Orion AZ-EQ G mount.
Thanks Andy.
There is not a lot of OIII, I ended up doing 8 subs of 15mins each to try and get enough signal added to 4.5 hours of 10 minute subs. My strategy with NB imaging at the moment is to try and get enough of each channel that I can get results playing with levels and curves without using any colour masks in PI (I guess selective colour would be the PS equivalent?)
Anytime I have to go masking, I am very rarely happy with the results, If it works globally, I know I have enough data.
