If the tilting plate was not strong enough, or the mirror was loaded, I would expect the collimation to change as the altitude of the scope changed. It measured the same throughout the latest imaging session.

Hi Adam,
It was just a thought as I remembered a thread on the stargazers lounge
about people modifying the GSO RCs.
I thought it was an RC8 but I can only find an RC10 here:

I am away from my home computer so I may be able to drag up the article
I thought I read - on the weekend.

cheers
Allan
