Astrodymium Ring System for Samyang / Rokinon 135mm f/2 Lens
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.
