My QHY163M’s TEC read temperature shows NA all of a sudden after 14 frames into the sequence, and it took forever and will not get out from “downloading”.
[05-27-17 00:55:17.021][DEBUG] [CP Update Thread] ASCOM Camera: Error in GetCoolerTemp. : value of CCDTemperature is invalid.

This is very annoying as I almost lose a night of imaging if I went to bed earlier… hopefully you can help, thank you!
Have you updated the QHY163m drivers lately? I would suggest trying that.
Just a suggestion to rule it out.
I took a series of 80 flat frames yesterday, cooling to -20C, without
problems with my QHY163M and SGP 2.6.0.23.
If you do not have the latest QHY driver, as Joel mentioned, you should definitely check those out. Also, if the problem persists, we will be in a better position to troubleshoot if you can also send the camera’s ASCOM logs. SGPro had been querying the camera’s temp successfully for hours and then the driver just stopped. I would be curious to see what the camera thinks is going on.
OK I just updated the QHY driver, restarted my computer, and the problem persists.
Attached is a log that I successfully captured 100 flat frames, and then wanted to capture 100 more flat frames when TEC temperature reads NA again.
To recover from this, I connected and disconnected from the Camera in SGP and it worked again.

Where is ASCOM Camera log please? I am not familiar with its location.
