The Antares 50mm finderscope brackets sports a dual-ring design with 6 alignment thumbscrews. Compatible with most finder brackets that accept Vixen compatible finderscopes.
In our opinion 6 points of adjustment are superior as they tend to offer greater adjustment range, and have less tendency to go out of alignment. There is less fussing around with return-spring systems which sometimes jam up. It doesn't require an o-ring, which tend to deteriorate over time.
