I have the TS9 OAG and I really like it .
I believe Meru here uses the same OAG with his RC8 and has no issues with a lodestar.
to use the TS9OAG with a dslr, these two products are invaluable as they do not add the 10mm that a normal T2-EOS adaptor does.
so its just DSLR -> OAG and maintains the 55mm distance if you're using a coma corrector.

you can order the TS9OAG with a variety of camera end interfaces
T2, EOS, M48.
same with the telescope end
T2 or M48.
