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. 


Stop Wasting Clear Nights, and Get Hassle-Free Imaging With Autofocus Instead

Imagine pressing one button at the start of the night, and waking up to flawless sub-exposures. Yes, this could be you. No more manually focusing in the dark, and no more ruined nights caused by bad focus! Powered by a ZWO EAF, and a reliable backlash-free belt drive.

Mount an ASIAIR + Guidescope (and other astro accessories)

Get longer exposures, and throw away less images with the power of autoguiding! Easily attach a guidescope, and accessories to your Rokinon lens, like an ASIAIR Plus/Mini (with the optional mounting plate add-on). Alternatively, you can purchase another rail and attach any astro accessory that has a vixen style dovetail instead.

Rotate Your Entire Setup in Seconds, No Tools Required!

You can have your cake and eat it too. The unique design of the focus ring easily allows you to disconnect the belt and reconnect it in mere seconds. You won't be locked in a single position anymore.

Used by Over 2000 Astrophotographers in 35+ Countries

"⭐⭐⭐⭐⭐I had my doubt when it comes to 3D printed parts. Happy to say I was very impressed by the design and quality of this ring system. All parts are precisely made and fit together perfectly. Almost all screw sockets are metal and very secure. It also has one of the best written instruction manuals to put everything together." - JUN

There's a reason why Astrodymium is trusted by astrophotographers around the world. All parts for the Ring System are made in Canada, and use high quality stainless steel / aluminum parts where possible.

Quick and Convenient to Install and Remove

Two rings securely hold your lens, and have an innovative design that keeps the thumbscrews in place so they don't fall out.

    It's a very well thought out system.

    I got great results last night using the Astrodymium Ring System that arrived all the way from Canada to Japan. The product is very accurate, the online manual is very clear and I was able to assemble it without any trouble. It pairs perfectly with my ZWO EFW 7x36mm. Thank you so much for sending me such a great product!
