Cumbrianwolf Posted March 2, 2022 Share Posted March 2, 2022 (edited) My feelings are that the scope cooled down a bit more than I expected after collimation and that the collimation went out? Or would I be barking up the wrong tree? Canon EOS 7D 254 mm F/4 1016 mm coma corrector and 30 second subs at ISO 400. Image below is not stacked and no editing.
