Astrodymium Ring System for Rokinon/Samyang 135mm Lens - ASIAIR/Guidescope Mount

Description

The Astrodymium Ring System is an all in one mounting &
autofocusing
solution to using the popular Rokinon/Samyang 135mm F2 lens for astrophotography.
The included OTA rings securely hold the 135mm lens, and use a hinged design, making removals possible without needing to disassemble your whole imaging setup. Large thumbscrews also means that no tools are needed to loosen or tighten the rings down onto the lens.
Attaching a guidescope to the lens is easy with the included guidescope rail. Simply slide the guidescope into the rail, and secure it with the two metal M3 thumbscrews. Other accessories that have a vixen style dovetail will also work with this rail.
On the sides of the hexagonal rings are M5 mounting points for easy attachment of additional accessories. Each threaded point uses
stainless steel threads
for a strong and corrosion resistant connection.
All parts for the Ring System are made out of durable PETG plastic that can handle temperatures of up to
75C (167F)
, and down to
-25C (-13F)
.
Screws for connecting the rings to a dovetail bar are included (two M6x16mm socket heads).
Lens is not included and is only shown for illustrative purposes.
