I am open to suggestions here. The mount I have is a Losmandy G11. The tak has a clamshell setup with the appropriate dovetail to fit the G11. I have spoken briefly to Paul (RR) about this and he suggests a set of rings for the tak and another dovetail setup for the ED80. I could use the Losmandy side by side plate, but that costs an arm and a leg and takes 6mths to get here if things are normal. Even then I would have to get another adapter to fit to the base of the ED80 to take another dovetail. It is getting all too confusing, so if anyone can come up with something that has worked for them, I would be most appreciative.
