Interesting and concerning at the same time!
Having checked and restored the clips, time to work on the collimation.
So, I now need to ask how you go about doing your collimation routine?
On a little side note, are you locking the focuser once you have the focus done? How firm do you have the tensioning screw too? You want some tension on it or it will leave the drawtube with too much slop.
