TelescopeControl plugin and Stellarium 24.2 crash

[Alephinfi1]

Issue: Stellarium v24.2 crashes if I connect to the scope using TelescopeControl plugin and ASCOM connection. I tried on two different PCs with the same result. If I'm quick enough to issue a slew command before the crash, the mount moves correctly, but then the crash arrives and stops everything. Of course I succesfully and reliably control the scope via other softwares, like NINA+ASCOM, so my setup is working ok.

Instead, telescope control works flawlessly using your app Stellarium Plus. There I use"Network" connection type, input Host IP and Port, and everything works very well.

Maybe the APP method could be used in the desktop application? If I'm not wrong it uses LX200 protocol. I know that TelescopeControl plugin has a "External software or a remote computer" option that allows to input Host IP and Port, but that doesn't work: despite scope gets connected, the slew commands issued by Stellarium don't actually move it.

Many thanks for your efforts in trying to fix this issue. Actually I find Stellarium the best way to point the scope around the sky, but this bug unfortunately prevents this use.

We know that ASCOM and Qt6-based builds of Desktop Stellarium don't work together, and task switching leads to Stellarium crashing. We know the symptom, but not the cure. Therefore we have disabled ASCOM in Qt6-based V24.3. You can use a Qt5-based build (the one that is labeled "for Windows 7 and later") with ASCOM, or use the native LX200 support (if your telescope is LX200-compatible). This used to work when I last had time to observe with my little GOTO mount, a few years ago.

Thanks, I'll try with Qt5+ASCOM.
For future development, please consider that my mount is connected to the controlling PC via Lan cable, so there's no serial or USB connection; as far as I know Stellarium desktop can manage this kind of setup only through the mount ASCOM driver. Instead, your Android APP appears to support it: the app connects to the mount through my Wifi network, diretcly to the mount's IP with no ASCOM drivers in the middle. That would be great to have in your desktop application as well, and it could maybe overcome the ASCOM issue of Qt6. Just an idea, maybe useless.
Many thanks!
