Hello Dan,
I tested QHY5-II both on Ekos and Lin_guider: the former detects the camera but it does not manage it via indy_qhy driver the latter detects and shows preview from camera even if time to time it crashes. I have never tested it on field so I don t know how lin_guider behaves with mount st4 command and so on. I am a programmer even if I haven t been programming on Linux platform so long, with your instruction, I could compile and test whatever you want so please do not esitate to ask me help on this.

Cheers,
Giovanni

Hello Giovanni,
I have opened my email address on the profile, please email me directly so we can keep the forum clear to the topic. Once we are done testing, we can post any pertinent result.

Best wishes,
Dan

Best wishes,
Giovanni
