Looks like the image is rotated and or shifted?

It's shifted.
Unfortunetely this happens with some chinese ASCOM drivers, when the subframe is big and has a width or a position not multiple of 2 or 4. Changing slightly the coordinates can (randomly) fix it.

Try to see if a new version of the ASCOM driver is available.

A possible solution is the option "Disable subframes" in the ASCOM plugin, but this makes the download much slower.

Some patches have been added for some cameras, if you like a possible solution for yours, please write me by PM or EMail.

Thanks for the swift response Fabio.

I’ll check if there is a new driver. Otherwise I’ll try your suggested hack.

My camera is an ASI1600MM Pro, I forgot to mention that.

PS:
Just got a Staranalyzer, extremely interesting and a steep learning curve.
