Stellarium is a free GPL software which renders realistic skies in real time with OpenGL. It is available for Linux/Unix, Windows and macOS. With Stellarium, you really see what you can see with your eyes, binoculars or a small telescope.
Synscan App connects to Stellarium via ASCOM and shows location of scope
Actual Behaviour
SynScan App connects but Stellarium fails to gather RA/DEC location of the telescope resulting in jerky Stellarium graphics and telescope location wrongly displayed - see attached screenshot and log files. Note log is for v23.4qt6 example of issue, v24.1qt6 is the same.
Synscan App worked reasonably well on Stellarium v23.3qt6 but on upgrading to v24.1qt6 successful connections were significantly reduced. Switched to Stellarium v24.1qt5 which also exhibits the issue but less frequently.
Steps to reproduce
Using latest version of SynSan App currently v2.4.31, with ASCOM SynScan App v1.4, launch Stellarium v24.1 then connect SynScann App to mount. At current scope location, (parked) open Telescope Control plugin and connect to the telescope using the ASCOM.SynScanMobile.Telescope. More often than not, the connection fails to retrieve the RA/DEC location of the mount.
Disconnect followed by Connect will eventually successfully recover the telescope coordinates.
