QHY9 using ASCOM driver problem (SensorType not implemented)

[Alexey Harchenko]

[+] Is the issue reproducible?

[+] Are you running the latest version?

[?] Are all prerequisites that are mentioned inside the manual met?

We trying to use QHY9 camera through ASCOM Remote (strange configuration dictated mostly by USB limitations), When NINA connecting to camera, it querying many properties, SensorType is one of this. But QHY’s ASCOM driver doesnt implement this preperty and fires exception.

After catching exception, NINA disconnects from camera and doesn’t work with it.

I think it’s bad driver implementation, but accroding to ASCOM Platform Developer Hel, ICameraV2.SensorType Property may throw a PropertyNotImplementedException if the sensor type is not known.

In NINA/Model/MyCamera/AscomCamera.cs/SensorType all non-standard cases defaults to Monochrome sensor type, and case if camera not connected too. But there are no exception handled and PropertyNotImplemented breaks CameraVM/ChooseCamera.

Really camera have a monochrome sensor.

Logs attached.

Thank You.

Thank you for the report. After consulting the ASCOM specs again, I agree that this exception is valid. Most likely it was missed due to some inconsistencies in the ASCOM documentation.
A 1.10 HF3 Beta Version will start soon, where this fix will be applied.
