I have no problem at all with your comments Timo and I can easily fixs these issues with image processes if they are even noticable? However, I'm very very happy with this now. As you say, when I replace the focuser, I might revist the DSI method with perfect robotic focus positioning.
For perfect stars I will use the worlds best telescope, in my opinion: TOA130F (Takahashi). However, I don't get anywhere near F6 and 2200mm focal length with that telescope.
No, I have for now put down the Allen keys and back away from the collimation screws. As John suggested in his post.
