Hi Ivo, you're talking about software binning? I thought hardware binning was different. On a camera you lose color information for an OSC and resolution for a mono as well but apparently I hear your SNR is better because signal ratio to readout noise increases too. Which is one real advantage. But if you have skyglow to start with and you bin 2x2 then flatfield/calibrate would you get a better result than no binning+calibration then software binning?
