Tip on Automating Calibration Frames with Shutterless Cameras

I set up a series like in the Wiki to take darks and biases for my ASI294 OSC camera. Started it and left for a while, came back in an hour to find nothing had happened. I forgot it would pop up a message to cover the camera lens and wait for ok. I like to take these frames in the night time while I sleep to reduce any chance of light leak.

What I did tonight was manually take a dark frame and click the ok on the Cover lens dialog, then start the script. It evidently “remembers” the lens is covered and happily goes on with the series.
