Created attachment 183807 [details] logfile Hi I have KStars 3.7.7 on a Raspberry Pi5 (Raspberry Pi OS - 64 bit). I took photos last night and I saw a very special issue (I had it never seen before). The main camera was the Omegon pro (Astroshop veTEC571C). With exposure time shorter than 1.5 seconds I got the fault: "Exposure timed out waiting for image frame". With longer exposure time I had (mostly) no problems. I use normally the loop function with an exposure time of 0.1-0.2 seconds for focussing the telescope. This was yesterday (and today) not possible. The guiding cam (zwo asi 120mm) worked without problems. Maybe there was a change in the settings - I don't know..... Best regards David
