So it does seem like this is the issue. I’ll contact QHY to see if they can address this behavior. Even with a cool down of 0 it still takes FOREVER for the temp to actually cool. SGP does not control the power. We only set the temperature. So setting a temp of -20 on my QHY11 I would expect it to eventually hit that temperature no matter how often I check that temperature. Apparently though, the QHY driver will only increase the power when we poll for the temperature. So if we never ask for the temperature the driver will never increase the TEC power to make the camera cooler. And likewise I guess it will only increase it a certain amount per poll.
We’ll decrease the poll period and I’ll also contact QHY about addressing this in a manner that doesn’t rely on the client asking for the temperature to make the TEC functional.
Dr Qiu said that he may be able to get a new version of the ASCOM driver out for the QHY22 and maybe the other older cameras that is incorporated into the new capture/guiding ASCOM drivers. This way all the cameras will behave the same as my 168C, which has no problem with v23. Also we will get ASCOM logging. Keep your fingers crossed…he said maybe this weekend.
I’m not sure about the drivers. But we addressed this a while back in SGP and it should be working in pretty much any version after 2.6.0.23. If you find otherwise please let us know.
