I got headaches from the geometries caused by my specific workflow, just 1 example:
- I need to catch 30 rapid dusk/dawn flats with constant light so I use local download (Raspberry Pi 3) and CR2
- these later converted to FITs for Siril processing.
- python check all options 5202/5184 x 3405/3465 and outputs only 5184 x 3405
I'm surprised the 600D indeed all canons don't suffer from same issue since as I understand the root bug lies in libraw.
