In this case bias frames should work fine. The option to choose the exposure time and do flat dar...

Thanks Robin. I went for 10% in the end , but I was still getting odd results from the brain so I ended up using the normal histogram

quick brain question

When using the Histogram brain what Read Noise Limit is usually the best to choose? I can choose from 1,5, and 10% as I remember.
