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 attached to the 135mm lens, making it a versatile tool for capturing stunning astrophotography images. 


Experience Hassle-Free Imaging Sessions With Autofocus

With a ZWO EAF (not included), and the EAF adapter add-on; it will be possible to electronically control the focus on the 135mm lens. This allows you to automate your imaging sessions, so you don't have to worry about focus shift due to temperature changes or filter offsets.

Quick and Convenient to Install and Remove

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 camera first. No tools are needed to loosen or tighten the rings down onto the lens.

Attaching a Guidescope is Easy

Simply slide the guidescope into the included top rail, and secure it with the two metal thumbscrews. This rail also works with other accessories that have a vixen style dovetail! (such as an ASIAIR).

Mount All Your Astro Accessories

On the sides of the hexagonal rings are M5 mounting points for easy attachment of extra accessories, such as an ASIAIR Pro/Plus/PPB Micro, with the optional mounting plate add-on.


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). Each threaded point uses stainless steel threads for a strong and corrosion resistant connection.

Screws for connecting the rings to a dovetail bar are included.
