Ok it looks like your problem is only triggered when you have everything running in Ekos. I would assume the problem doesn't manifest itself if you just run Ekos with the DSLR camera and capture with it?

Well indeed, i ended last night shooting 10m darks and no problem occurred. I have 20 darks sitting in a directory without a problem. Sub 20 was sitting in the FITS viewer, so also no problem there it seems.
So it's only the lights, which require guiding also.

I will enable KStars logs to see what happens. It seems we will have a clear night tonigt, although with a first quarter moon.
