Recently purchased the ASIair Plus and noticed an issue with camera resolution when using with the ZWO 2600MC-P camera. The camera resolution is 6248x4176 and when 2x2 binning it is 3124x2088. This is eaxactly what I get when using astroImager (I am a MAC user). However, when I use the ASIAir plus, i get a resolution of 3120x2088, a loss of 4 pixel columns. Not a show stopper, but i do not what to redo every set of darks i have created. Can anyone explain why whenI use 2x2 binning I loss 4 pixel columns???
