I noted that support for QHYCFW1 filter wheel was added recently - is this the original filter wheel that shipped with a QHY9, or is this another wheel?
The commands look similar. If its the older one going back to 2009, I can test it.
I just added it by feedback of a StellarMate user from Japan. Not sure which model exactly it applies to, but the earliest unsupported models. Testing would be appreciated.
Apologies for the tardy response. I tested it and it works well. I'm not sure what the model is, but it is the filter wheel (5 x 2in filters) that shipped with the early QHY9 CCD camera.
To make this work, I used a USB-to-serial adapter (with pl2303) and built a serial cable using the pinouts found on page 4 of the attached doc.
