Hello,

Indeed, this project is very interesting.

I was checking the github repo for the project and I noticed that the ASCOM implementation consists of two different drivers:
1- focuser driver for the motorized OAG/double helical focuser
2- filter wheel proxy/wrapper driver that commands a parameterized movement of the OAG focuser each time a filter change is requested (this piece is focuser and filter wheel agnostic)

For INDI, a similar solution would require an auxiliary filter wheel driver that acts as a proxy that intercepts each filter change and dispatches the filter change to the filter wheel driver and also dispatches the refocus movement to an OAG focuser driver (or any other focuser driver).

Unfortunately, the closest conceptual solution to this I found for reference in INDI was the weather safety proxy, but it differs a lot in its implementation.

Cheers,
Andre
