Hi, I am using a STL 11000 camera on a Tak FSQ106,

Here is what I have for files ,

Bias Frames,

LRGB - Flat Frames with matching Darks

LRGB - 500 second Lights all the same exposure  with 500 second Darks

questions, should I use the the darks that go with the Flats?

should I then make master calibration frames?

finally make master LRGB  light files and combine ?

Thanks for any help.

Hi Richard ( @richard85392 )

In this case, yes, use the matching darks for the flats, they need to have the same gain and offset, temperature and exposure time as your flats. From those darks, make a masterdark and use that masterdark in calibrating the flats.

I would also recommend to make a Bad Pixel Map from your flats and darks, that will improve calibration results for your lights significantly:


Make the integration per channel and yes, then load them into the RGB combine tool.

Be aware, that you need to have the channels registered to each other as well. There are several ways to do this.

Let me know if you need more help 😉
