My 2600MC-duo camera, controlled by NINA, generates greyscale images.
The bayer pattern is set to RGGB (but I also tried Auto, makes no differnce)
Under Image Options I tried both Debayer ON and Debayer OFF (no difference)
Save as FITS or TIFF again no difference.
My driver is ZWO_Cameras_driver_3.24.0.0
I assume I have a wrong setting in NINA, but I may be wrong.
Appreciate your help.
