No, you are right - the geometry is not that bad. Time to revisit the AO.
I really appreciate you taking the time to check this - I had written it off as an option some time ago, without looking at it closely enough it seems.
Do you have any feel for the problems introduced by uncorrelated turbulence along the guide and imaging paths? Much of what I found deals with big scopes with full adaptive optics - not much info to date on how big the low frequency correlated region is for a smallish scope in sea level turbulence. I guess I could go back to the theory, but I don't really want to - much better to find a useful rule of thumb. Maybe I should just image the moon for a while and see how big the regions with coherent motion are.
