Mainly just stack and look as well as compare with the other filters, if one is really noticeably different in quality I just take more. My Ha and SII filters are also 5nm so they collect a little more light than the OIII (3nm).

Yeah, it was at F10 as well. But I wanted to try and reduce the noise especially from the 3nm OIII filter, as the signal was low on that one. I should really get more OIII, as there is still some noise in that filter - maybe next season. 🙂

Thanks for sharing!

Thanks! I ended up capturing about 85hrs of SHO data but omitted some of it due to subpar data and ended up with an integration just shy of 77hrs. Al the SHO was captured from bortle 7 and the RGB for the stars was from bortle 3-4.

Thank you Jacob. I appreciate it!
