The same image solved with the app Astrometry of CloudMakers detects a normal field rotation a about 180° due to the fact that I recorded this image with an HyperStar lens. I solved the problem. In CCD Simulator/Simulator Config/Simulator Settings, I set the Rotation CW to 90. Everything works as expected. NO everything is not OK because these rotation angles of 90° or 180° don't reflect the random orientation of the camera ! Can you share a link to the FITS image you captured for this field? Here is a photo of M81 taken at an angle of 117.89° with a ZWO ASI1600MC-C camera. KStars displays the right angle before solving. But sets it back to 90° after solving. http://dl.free.fr/fWFp9aQya I wanted to say "KStars displays the CORRECT angle before solving." " It's correct. There is a difference between astrometry.net Rotation and KStars internal representation since KStars reads FITS starting fro TOP-LEFT and not BOTTOM-LEFT as astrometry.net does. |
Created attachment 117810 [details] FOV rotates by 90° SUMMARY The solver FOV rotates by 90° at the end of the operation STEPS TO REPRODUCE 1. Solver panel. Click on Load & Slew to select a FIT file. OBSERVED RESULT 2. Everything is OK and the solver draws the FOV 3. But at the very end, the FOV is rotated by 90° EXPECTED RESULT It should not rotate SOFTWARE/OS VERSIONS Windows: MacOS: 10.14 Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
