At the Moment I use the Native Setting in indi, so I save the .raf file from the camera remotly or Locally.
If you remove the de-bayern option in indi -> FITS the mesage that the filter patern "GGGG" is wrong, it disapear, but than you have the FITS files which cannot be used...
SO I suggest at the moment to use the native file setting in indi &/or in EKOS in capture mode...
Hopefully in future will be added something to filter the X-Trans to be used later from the FITS files...
but for now that's it..
If someone else have something better to do, pleae go haed ...
