Description Jean-Claude 2019-03-01 16:22:08 UTC 
SUMMARY
The Rot parameter should indicate the actual rotation of the camera relative to axes.
Hence this angle depends on how the photo was captured
In my case, the Rot angles of astrometric solutions for different targets are ALWAYS very near to 90° or 180°

STEPS TO REPRODUCE
1. In the Solver panel, Load & Slew already recorded FITS files
2. 
3. 

OBSERVED RESULT
Rot is always very near to 90° or 180°

EXPECTED RESULT
It should vary continuously between 0° and 360°

There is nothing wrong with that.. if it is 90 or 180, this is what astrometry.net resolves in respect to north pole. It's measured in degrees East of North.
