Rokinon/Samyang 135mm f/2 Ring Kit

The Rokinon or Samyang 135mm f/2 lens is a favorite among astrophotographers, remaining in their kit even as they upgrade to larger equipment. The nrStellar Ring Mounting System is designed to last as long as your Rokinon, creating a reliable deep-sky astrophotography rig you'll use for years.

Why Choose the nrStellar Ring System?

Key Features:

• Customizable, Modular System: Mix and match add-ons to customize your setup with an autofocuser, guide scope, ASIAIR/MiniPC, and more
• Easy Lens Rotation: Geared autofocus allows for easy lens rotation with zero added backlash
• Premium, Carefully Selected Materials:
  • 18-8 stainless steel threaded connections resist rust and outlast direct plastic threading. Embedded nuts provide stronger pull-out resistance than threaded inserts.
  • Carbon fiber-infused PETG rings and add-ons offer better temperature resistance and rigidity than standard plastics. Our custom blend of carbon fiber PETG performs better than commercially available PETG-CF blends. 
  • Waterproof, closed-cell EPDM foam liner holds your lens securely without pressure points
• Increased Rigidity: Reduce camera sag with our camera support (see compatibility list below)
• Low Center of Mass: Makes the most of your mount’s payload capabilities by moving the heavier add-ons to the lower add-on mounting locations.
• Compatibility: Works with both the normal and the cinema versions of the Rokinon/Samyang 135mm f2 lens

All nrStellar products come with a 2 year warranty. If you experience any issues, just shoot us an email and we’ll sort you out.
