Hi all, I am pretty new to using my ZWO ASI1600 mono cooled camera (my first cmos camera) and I am currently trying to wrap my head around sub length and gain in relation to particular targets.

I have done my research on forums and watched quite a few videos. I found the work from the Sharpcap creator Dr Robin Glover the most comprehensive.

For my FSQ106 f5 refractor the numbers are telling me with my estimated 4.2 bortle skies that I should be around here these durations for each filter at 100gain:
Lum 26 seconds
RGB 79 seconds (3x Lum)
NB (3nm) 44mins (100x Lum)

My thinking at the moment is that 100gain would work for LRGB but that I should maybe increase the gain to 150 for NB work and bring the optimal sub length for NB down to 28mins.

Does this seem a reasonable start point?

Cheers
Brett
