Hello,
While my ASI2600 is being repaired by ZWO I am trying to use my Nikon D5500 for imaging.

When I shoot just with the camera (no computer control) or with Ekos set to NEF (Raw) and Native, I get 6016x4016 frames.
Interestingly, Pixinsight and Affinity report 6016x4016.
APP reports 6016x4016 6000x4000.
Photoshop and ACDSee report 6000x4000.

When I switch Ekos to NEF (Raw) and FITS, Ekos starts to shoot 6000x4000.
All software report 6000x4000.
I do not like that since I have a library of Dark/Bias masters shot at 6016x4016 and most often use D5500 without Ekos.

I want to stick with 6016x4016 which means NEF (Raw) and Native.

However, in this mode the preview shown in FITS viewer is converted to 8-bit and overexposed while the actual (saved NEF) image is 14-bit and not overexposed.

With Ekos set to NEF (Raw) and FITS the preview is fine but the frame size is not right.

Am I doing something not right or is it just the way it is?

Thanks!
