The ASI6200 has a pixel size of 3.76 um- over sampled for long focal length instruments. However in the case of the Celestron RASA 11 which I'm using the smaller pixel size might be advantageous.
If I image at 1x1 bin which will be 1.25 arc secs per pixel that would be nice but the files would be pretty big at 32 mb each or 64 mb at 32 bit. I could image at 2x2 bin but I feel I would be possibly, depending on conditions, lose precious detail as the exposures I intend to use are 10 seconds each so effectively lucky imaging.
So if I took the images at 1x1 bin then rescaled these in PI to say 3x3 bin would I be losing or gaining anything?- I'm not sure how rescaling works with CMOS cameras. If there is a better way then let me know but I'm anxious to get maximum resolution with good signal under my very poor skies.
Please let me know your thoughts.
Clear skies to you all & stay safe.
