I have recently received my first CCD camera. (Orion G3 Monochrome, 1/2" sensor, 752 x 582 pixel array)
I came up with a pixel size of 9.5 microns in ISIS using the Alpy 600 with the 3mm hole, darks, bias, no flats.
I used my small Newt, 130mm obj. at F/5 and came up with a resolution of 105 in ISIS.
Does this sound normal?
Also, as there are still glaciers in my backyard here in Minnesota, USA, -0 degrees C., is it necessary to use CCD cooling?
I will try to attach an image of Sirius.
Thank you for any advice.
