I'm having a couple of problems with my R6 Mk II, the first of which has really been a bear:
The actual images should be 6000x4000 px, but everything from the ASIAIR Plus is 6188x4120. It looks like the ASIAIR adds a black border on two sides and a thin white border on the third:

In my searching around the internet, it looks like this might be related to bug report BT20250107862898A, but I don't have Facebook so I can't tell for sure.
My second problem is the auto exposure for taking flats fails immediately no matter what I try.
Have you found a way around either of these problems? Thanks for your time!
