Hey
I have a question about the exposure gain calculator. I have a zwo1600mmc Mono cam. when trying to find the best exposure and gain settings. Do i use the filters lrgb and narrow band when pointing the scope at dark sky?.
Cheers
Andy

Hi Andy,
Yes, you use the filter that you intend to image with when taking a measurement of the sky brightness since using a colour filter will reduce the background brightness by a factor of about 3 and using a narrowband filter will reduce it a lot more than that – both of those will lead to longer predicted exposures.
