SBIG T- to C-mount Lens Adapter
The SBIG T- to C-mount Lens Adapter connects any camera with an M42x0.75 T-thread to optics with a C-mount thread, backed by a 1-year warranty. This simple adapter opens up a wide range of imaging possibilities by allowing you to pair standard astronomy cameras with specialized C-mount lenses designed for microscopy and security applications.
Universal M42x0.75 T-Thread Camera Interface
This adapter features a male M42x0.75 T-thread, a common standard for attaching accessories to astronomical cameras, so it fits any camera with an M42x0.75 T-thread. The adapter threads directly into your camera's T-thread, creating a secure mechanical connection for your optical train.
Accessing 1-inch x 32TPI C-Mount Lenses & Microscopes
The female side of the adapter features the standard 1-inch x 32TPI C-mount thread. This allows you to attach a variety of optics not typically used in mainstream astrophotography. You can now use your high-sensitivity astronomy camera with compact security lenses for meteor detection or all-sky imaging, or connect it directly to a microscope's C-mount port for scientific imaging.

What is the SBIG T- to C-mount Lens Adapter used for?
This SBIG adapter allows you to connect a camera that has a standard M42x0.75 T-thread to a lens, microscope, or other optical device that uses a C-mount thread. It physically adapts one thread standard to the other.
Will this SBIG adapter fit a non-SBIG camera?
Yes. The adapter uses the industry-standard M42x0.75 T-thread on the camera side. It is compatible with any camera that uses this common thread for connecting accessories, regardless of the manufacturer.
What kind of lenses can I use with the SBIG T- to C-mount Adapter?
You can use any lens that has a male C-mount thread. This most commonly includes:
-
Microscope optical ports for photomicrography.
-
Small security camera lenses, which can be used for wide-field applications like meteor monitoring or all-sky imaging.
- Certain industrial or machine-vision lenses.
How do I install the SBIG T- to C-mount adapter?
Installation is straightforward. First, thread the adapter's male M42x0.75 T-thread into your camera's female T-thread until it is snug. Then, thread your C-mount lens or microscope adapter into the female C-mount threads on the adapter.
Can I use the SBIG T- to C-mount adapter to attach a microscope's camera port to my astro-camera?
Yes, this is a primary application for this adapter. If your microscope has a standard C-mount phototube (a common standard), this adapter will allow you to connect your M42-threaded astronomy camera directly to it for high-resolution imaging.
I have a small C-mount security lens for meteor watching. Can I attach it to my M42-threaded guide camera using this SBIG adapter?
Yes, if the guide camera has an M42x0.75 T-thread. The SBIG T- to C-mount adapter threads into the camera's T-thread and your small security-camera lens threads into its C-mount threads.
