Thank you for this post.
I am using the M-Uno with the STARGO2 Pro. I have an RC10 with a field flattener/reducer. Focal length is thus 1385 mm.
I will try your PHD2 settings and a direct ethernet connection! I have issue with stable connections via WiFi with PHD2, although I have a very reliable local WiFi mesh set-up.
@c.granwehr@bluewin.ch. I hope I am not too intrusive: I also live in Switzerland. Maybe we could exchange our experience directly. This weekend is supposed to get clear skies again :-)
