Hi all

I just bought myself a 1600mm pro from a member and I'm pretty excited to finally dip my toes into the world of mono imaging.

I'm in a bortle 6/7 zone in Melbourne
My gear is an EQ6-5, William Optics ZS73, Uniguide 50/200 scope with ASI 120mm mini for guiding, NUC with Kstars/Ekos installed. Zwo Electronic focuser, 1600mm Pro with filter wheel and zwo filters LRGB Ha Sii Oiii

I've started to have a look at gain setting, offsets etc... which is pretty new to me coming from DSLR imaging...

Found some great Excel sheet calculator on here and cloudy nights.

From what I can gather with my setup and my sky people suggest suggest a gain of 75 for LRGB and for narrow band 139 (unity gain) or 200 and then setup exposure time resulting in an adequate background sky value, does not clip too many stars, and does not result in an excessive number of subframes.

I'de be keen to hear what your settings are with comparable sky and equipment. My primary targets are Nebulas.

Many Thanks!
