Description
The Astrodymium Ring System is an all in one mounting & autofocusing solution to using the Rokinon/Samyang 135mm F2 lens for astrophotography. The ring system allows a ZWO ASIAIR, EAF, and any guidescope to be easily connected to the 135mm lens.
The included rings (lens collar) securely hold the lens, and use a hinged design, making it possible to remove/install the lens without needing to remove your DSLR / imaging camera first. 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 top rail. Simply slide the guidescope into the rail, and secure it with the two metal 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 extra accessories, such as an ASIAIR Pro/Plus with the optional mounting plate add-on. Each threaded point uses stainless steel threads for a strong and corrosion resistant connection.
All parts for the Ring System are 3D printed out of durable PETG plastic that can handle temperatures of up to 80C (176F), and down to -25C (-13F).
Screws for connecting the rings to a dovetail bar are included.
