Alexander, good day!
Great work!
I also bought a ZWO 294 MM.
I have a question, if possible:
For bin 1 and bin 2 modes, do I need to take different darks?

And one more thing.
When switching from 46-megapixel mode to 11-megapixel mode, as I understand it, the binning in the program remains at 1? There's no need to switch to binning 2?

Good afternoon, Alexey!
Yes, absolutely! For each binning setting, all calibration files are specific.

Everything is correct. I switch binning manually. If you're shooting with NINA, you can create separate profiles for each mode and simply switch between them.
