Hi, what range of gain are you guys using with the 6200mm pro for NB and for LRGB? i got the Astronomik 6nm NB filters and LRGB ones.

I'm also using 100 gain for everything with the default 50 offset. But I've only just begun playing with it so not sure yet if that is optimal.

Personally I want maximum dynamic range without super short exposures (those files are big!). So I use gain 0 for LRGB and gain 100 for narrowband. Gain 0 gives me maximum dynamic range at around 3.5e- read noise which is easily swamped. Gain 100 is the magic number where the read noise drops to 1.2e- which is nice for narrowband.
