You can shoot darks indoors at night anyway. That's what I do, on the kitchen table. Just the camera. |
I prefer to shoot the darks on the scope just so I dont have to reorient it the next night im shooting. Is there a way of checking uneven cooling? I don't have this issue if I take darks at night but obviously I don't want to waste a good night of imaging imaging darks!
