Greetings!
So this skies magically cleared in the middle of constant rain last night, so I quickly attempted the North American Nebula with a 6D MKii and a Rokinon 135 f2, no filters, Star Adventurer, no guiding, Bortle 7-8, un-cropped, APP defaults. (My preferred APSC camera + clip-in light pollution filter not available). Sure enough clouds started back in, so only 24 x 45" (18 minutes) of data; (102 minutes trashed). Obviously not a lot of signal so I'm not expecting anything decent, but I'm really puzzled by the big ring in the centre of the image. Looks like something caused by the camera, but what? Don't want a repeat in the future!
TIA,
Mike
