Please try to use the INDI V4L2 driver as it works better with UVC cameras.
This is a downstream issue. INDI does not install fxload. Should be installed by the system.
I have the exact camera model and cannot produce a crash. Please use EkosDebugger to submit the backtrace (https://stellarmate.com/support/tutorials/ekos-debugger.html)
That's the client's responsibility. Please contact SkyCharts developers.
It depends on the client. If you use KStars, it would be filled automatically.
It needs to be ISO8601 format!
