M68-CRING

Alpine Astronomical

Part of a two-piece system, the Alpine Astronomical Baader M68/S68 Dovetail Quick Changer Ring allows fast installation and removal of gear without having to screw/unscrew pieces together, which saves time and hassle without the risk of cross-threading components. The quick-coupling design screws onto male M68 threads and uses a circular dovetail-type system with the optional M68/S68 Quick Change Clamp that accepts the ring and secures it in place with a simple thumbscrew. This is an ideal mounting system for a variety of gear like the Baader Solar Spectrum H-alpha filter, Baader Flat Field fluorite Converter (FFC), and other gear with male M68 threads.
