Is it advantageous to bin 2X2 OIII and SII for a SHO image?
I am imaging the Bubble Nebula right now where the OIII and SII content are not very high. I already have a good Ha stacked image. Would it be advantageous to proceed with binning 2X2 for those 2 gases in other to pack more subs in the few cloudless nights I get? Or would the image end up be too grainy at the end?
