The Astrodymium Ring System is an all in one mounting & autofocusing solution to using the popular Rokinon/Samyang 135mm F2 lens for astrophotography.

The two OTA rings feature a hinged design, making it possible to remove/install the 135mm lens without needing to disassemble your imaging setup. Large thumbscrews also means that no tools are needed to loosen or tighten the rings down onto the lens.

By default a 96mm long guidescope rail is included. Simply slide the guidescope into the rail, and secure it with the two included metal M3 thumbscrews. Other accessories that have a vixen style dovetail will also work with the rail.

On the sides of the hexagonal rings are M6 threaded mounting points for easy attachment of additional accessories. All threaded points use partially hidden steel components for a durable connection.

Screws for connecting the rings to a dovetail bar are included (two M6x16mm socket heads).
