I am trying to get my head around the use of the Batch Preprocessing script which does indeed seem to make short order of calibrating, aligning, and creating master frames. Where I run into an issue is using my PI created master flat frames. I use ACP for automation and that uses MaxImDl for camera control. One of the very usefull scripts in ACP is autoflat. These flats are taken and then I use PI to creat my master flats. For whatever reason, PI's batch preprocessing script doesn't seem to like these masters. I haven't tried just loading the calibrated flats and see what happens which I will do next as I just thought of it. But seems I read a post where Juan mentioned that there was a problem with sky flats because they all have different exposure times as the sky darkens/lightens. Is there a way around this issue?
Also, while watching Harry's very informative video on using this script I noticed that the cosmetic correction script I have doen't have the preview feature so you can see what affect the settings are having. Can someone advise what I'm doing wrong of is there is another version of the script to use?
Thanks as always,
Steve
