ok so you have 2 issues, collimation and focus, I would say that you need to get the collimation spot on or you'll be chasing your own tail for the focus.

it just crashed again and messed up the coordinates again, they swapped. I will see if there is a log file...
Kstars 3.5.0 has been very stable, I was about to put a post about it and then I kid you not 30 sec after I thought about the stability the all thing went batshitcrazy on me. Very spooky.
First time this actual error happened ever. I fixed it after figuring it out, and I'm running 2 sessions now.
One thing that's not quite working well is the guiding, I think I may have a log and will post it another timer, something about exposure timeout.
I think this is defo out of focus, have you checked your backfocus? Are you at the right distance for your camera?
Somehow, the latitude and longitude got swapped I think...
I may have figured it out...
Compared 2 locations in Germany, mine and another place, check this out.
Another place not mine
Something very odd just happened. Kstars crashed for no apparent reasons, on restarting it my sky orientation is 100% wrong.
I have tried both, there is something odd going on.
To reproduce what I've noticed:
start Kstars then click in the following order
View > Full Screen Mode (first option) (it goes full screen)
