I've been doing a lot of research recently with respect to Coronado etalons and was curious if the Coronado Adapter plate product number was related to the ID of the plate itself.
I have an ED80 and would like to get a SM60 etalon for it and a BF15 (after advice from Merlin). I'm having problems sourcing what I think is an AP113 plate (my O.D. is 111mm)
Can anyone confirm that the number is *actually* the I.D.?
I'm purchasing everything for pick up in the USA, so I don't have much room for mistakes...
This link has the full range of them... if anyone can measure their refractor and confirm the OD versus the associated plate, it would be greatly appreciated.
