Andrew et al, Ian Bruce - the software writter for SX - is onto it. I sent him one of the files.
The images are totally unbinned, so the size is odd. SX software allows it. If I capture with Maxim, the pixel size is indeed 3024 x 2016. Perhaps this is what PI is finding problematic, as all the 3024 x 2016 files integrate,calibrate, debayer, stack etc just fine in PI.
Andrew, would love to try it but I have neither of those programs, nor would I know what to do with them
CMD Line stuff is not my forte
FITS Liberator cannot assist with it???
