I have been using Ekos/Indi for a few years now, starting with the AstroPi script. I have a QHY5L-II-M and 163M. I frequently had "stability" issues, but it is hard to say whether this was from indi/ekos or the QHY drivers themselves (after all, QHY's EZCAP_QT will still crash on my on my PC and Mac). Or was it my hardware, since I was using SBCs? I used a Rock64 setup until recently, and on that Ekos/Kstars would certainly crash now-and-then. I just got a Raspberry Pi 4 and installed Astroberry, but the weather has only been decent once. Everything seemed to go smoothly until .... Best I can tell, the vnc server died or wireless networking died while I wasn't monitoring the session, according to the logs. My sequence completed though, and I got an image of the Atlas comet before it broke apart.
