I'm sure you are right. When I made these series I had a significant PAE (26') because they were part of test cases to challenge a bit the guiding capabilities of Ekos. But I was not aware, that the resulting image rotation could not be fully compensated by OAG guiding.

But next time I will be ware.
Many thanks again!
