I am using the latest generation of QHY filter wheels, CFW3. I have two. The filter wheels can be used via serial cable connected to a QHY camera, or via USB. The USB connection actually uses a serial COM port.
I have identified a repeatable problem with the USB/RS232 connection that causes SGP to simply close with no warning. Here are the steps:
- Open SGP
- Choose filter wheel (QHYFWRS232 FilterWheel)
- SGP then asks to import the filter names - choose YES
- The filter wheel is connected
- If I then try to open the filter wheel settings (ASCOM driver) SGP closes.
If I disconnect the filter wheel first, I can open the ASCOM driver settings. So basically, any time the filter wheel is connected in SGP if I try to open the settings it will cause SGP to close without warning.
This isn’t a bid deal since the filter wheel works properly, but I thought I’d mention it since SGP doesn’t even give a warning dialog. LOG FILE
