Hi!

So I think I got it all figured out with the help of Jasem. I'm running latest Kstars on a Stellarmate.
When platesolving, the CRVAL keywords are included for that very camera. However, when we do spectroscopy, plate solving is not done with the imaging camera.

To have these keywords, I do the following:
1. Plate solve with my positioning camera (I have a separate positioning camera, others use the guider)
2. Go to Indi control panel for the Imaging camera, the main camera
3. Go to the tab WCS
4. Enable WCS
5. A new line appears: Rotation. I set rotation to 90, because that is what my positioning camera shows (does not matter for spectra). I set this value.

Now CRVAL appears in the fits header also for the imaging, primary, camera.
