SBIG C-Mount Adapter for RGH / ST-I
The SBIG C-Mount Adapter for RGH / ST-I is the factory-original lens adapter for connecting security-style C-mount lenses to your guide camera, and is covered by a 1-year warranty from Diffraction Limited.
Connect C-Mount Lenses to Your SBIG RGH and ST-I
This adapter allows you to attach any lens with a standard male C-mount thread to your SBIG Remote Guide Head (RGH) or ST-I autoguider. It is the identical component included in the RGH Guider Kit, which uses a Kowa C-mount lens. By using this adapter, you can build a compact, lightweight guide system around a C-mount lens.
A Factory-Original Diffraction Limited Part
This C-mount adapter comes from Diffraction Limited, the maker of SBIG products, and is the same adapter used with the Kowa lens in the RGH Guider Kit. It provides the female C-mount connection for a security-camera style C-mount lens on the Remote Guide Head or ST-I.

What cameras are compatible with the SBIG C-Mount Adapter?
This adapter is specifically designed for the SBIG Remote Guide Head (RGH) and the SBIG ST-I autoguiding cameras.
What kind of lenses can I use with the SBIG C-Mount Adapter?
You can use any lens that features a standard male C-mount thread. These are commonly found on industrial, machine vision, or security-style cameras, offering a wide range of focal lengths in a compact form factor.
Is this the same adapter included in the SBIG RGH Guider Kit?
Yes, this is the identical, factory-original adapter that is supplied with the Kowa lens in the complete SBIG RGH Guider Kit.
I have an SBIG ST-I and want to build a wide-field guidescope. Is the SBIG C-Mount Adapter what I need?
Yes. This adapter fits the ST-I and lets you attach a C-mount lens, which makes a compact, lightweight guide system.
How do I install the SBIG C-Mount Adapter on my Remote Guide Head (RGH)?
The adapter fits the front of the SBIG Remote Guide Head and provides the female C-mount connection; your C-mount lens then threads into it.
Why would I use a C-mount lens for guiding with my SBIG camera instead of a traditional guidescope?
A C-mount lens and an SBIG guide camera create an extremely compact and lightweight guiding system. This is beneficial for several reasons:
-
Reduced Weight: Lessens the load on your mount.
-
Minimized Flexure: A short, rigid setup is less prone to differential flexure that can ruin long exposures.
-
Portability: Ideal for travel rigs or mounting on top of a primary telescope tube without causing balance issues.
