I am completely new to INDI but from I found so far this looks like an impressive project. I am eager to try it out but can't find support of my autoguidre yet. Do you know if the QHY5L-II are supported or whether support is planned?
It might be possible... I will be trying to create a unified QHY driver using QHY's SDK for Linux, but since I don't have the actual hardware, I will not be able to test it. My camera is the QHY5-II (no L), so it's a bit different, but both are supposedly supported by their SDK... Mine doens't quite work, so I've told them and also I am looking into it.
In the meantime, you can use lin_guider, which is what I used last night out and worked very well, you should be able to find it with a google search. It supports both the QHY5-II and the QHY5L-II, and a few others...
