OAG and Moonlite Focuser

Hi All

I find myself in a bit of a spot I have a meade 14in LX200R sitting on the back of a losmandy titan. Piggy-backed onto the 14in I have a 5.5in Celestron Maksutov as my guide scope.

My arc-sec per pixel is relatively close. I am using a SBIG STL-11K with remote head for guiding. 0.52 arc-sec through the 14" compared to 0.76 arc-sec through the guide scope.

When I actually manage to find a guide star through the celestron it guides away quite happily with maximum errors of about 1.2px + or - of 0, without PEC. However when i come back to see what i have manage to get the stars through the main scope are egg-shaped. My conclusion is differential flexure

Enough with my life story

I am looking at getting an OAG and am wondering what my options are seeing as I have a Moonlite focuser hanging off the back of the 14". Are there adapters to fit something like the Astrodon MOAG onto the moonlite and in turn mount that to the focuser?

Any info would be much appreciated

Ben
