Testing new ASI camera, I am very impressed by the quality and capacity of this camera, it the time to change the scope to APO or RC :) 420 sec.x6 only, 4 darks, gain 139, temp. - 25 C. Finally got cold and clear night and check the capacity of the camera, great!!! A lot to learn as to processing but I am motivated now.
