New Guide Scope Mounting

Hi all,
I thought I would post a photo of the guide scope mounting, so that it would be clear what I had done and how it actually looks.
This photo shows the whole scope and guide setup with labels.
This three ring setup seems to be very solid, plus it is all off the shelf and easy to install.

This one shows a close up of just the three ring mounting of the guide scope and camera.
Note the spacer blocks on the focuser ring, they bring it up to level with the larger rings.

Did I miss the report on the performance opf the new setup. The pictures look good. My problem is that I still think my problem is mirror shift. Has anybody come up with a control for mirror shift in a Celestron?
