Hi all
I've created a new page describing my initial experience with the GSO RC pointing accuracy. It also includes some pics from the disassembly.

In summary my primary mirror was loose, causing all sorts of problems.
I've also simplified and moved my collimation guide:

I hope you find it interesting / useful.
