Well, Ok, the Antares has arrived today, yay. But I still need to see if I can resolve the shipping charge.
The Antares also has two set screws, rather than a compression ring. I think these are often replaced with nylon screws to help prevent marring the EP barrels. I wonder how firm they hold?
Interesting that more recent CN posts suggest that the Antares (and probably the Proxima) actually provides magnification factors of between 1.4 and 1.6 depending on which fl Ethos you are barlowing
