The next day, I thought to check if the scope maybe hit the pier and couldn't move - and yes, it seems as if there was the chance that the filter wheel hit the control box:
I tried a few things:
- Moving the control box lower? Didn't work as the guiding cables aren't long enough.
- Moving the control box to the front (the scope is never anywhere near the front of the pier - but same as before, the RA guiding cable isn't long enough
- Rotating the pier such that the box is exactly in the back (and thus destroying my polar alignment). Yes, that seemed to work.
Last night, no collisions - yei!
Though it does seem weird that I have to do this exact setup and that I never experienced that before (I'm sure I didn't always have the control box exactly in the back)...
