Camera Adapters

How do you attach your camera?

Over the years, Optec has developed dozens of adapters and custom fittings for various cameras and mounts. While most astronomical cameras have a female T-thread mount, many of the larger chip cameras are now being offered with even larger mechanical interfaces, such as the relatively new 3-inch 24tpi female mount available on Apogee, SBIG, and a modified version on the FLI cameras. However, there are a variety of other mounts such as the STL 4-bolt mount.

We classify our camera mounts by the size and shape of the "telescope" side mechanical interface for a typical configuration. These mounts correspond to many of our astronomy products. For example:

  • OPTEC-2300 Camera Adapters for use with the Pyxis rotator, IFW Universal Mounting Ring, and Perseus 4-port parfocalizing rings.
    • The OPTEC-2300 circular dovetail mount is used for the TCF-S focuser and IFW filter wheel to allow easy connections from most any camera. If your scope or accessory is not listed, do not hesitate to call.
  • OPTEC-2380 Mounting Rings are threaded mounts for use with the IFW and MAXfilter systems. 
    • The OPTEC-2380 circular dovetail mount is used for the IFW Intelligent Filter Wheel and Perseus 4-port selector parfocalizing rings to attach most cameras and accessories.
  • OPTEC-3000 Dovetail Mounts for use with the 3-inch TCF-S3, Pyxis 3", and IFW-3.

OPTEC-3000 3-inch Mounts

3-inch Adapters for the TCF-S3", Pyxis 3" and IFW 3"

Optec 3-inch "Push-Fit" Mount

The OPTEC-3000 3-inch mounts "push-fit" into any 3-inch receiver including the TCF-S3, IFW-3 #17367 Rear Cover Plate, and Pyxis 3" rotator. Similar to a 2-inch eyepiece barrel or 2-inch camera nosepiece, the OPTEC-3000 series appears as a 3-inch nosepiece for convenient, yet secure mounting. All the OPTEC-3000 mounts have a machined dovetail to match the thumbscrews, setscrews, and other mounting hardware for all our 3-inch product line.

If your camera or accessory is not listed, do not hesitate to call. We are constantly adding new adapters to our catalog.

        Scarlett ★★★★★

        The machining is precise and the threads engage smoothly on my SCT—no frustrating wobble or tilt. Finally, a solid connection that keeps my camera square to the optical axis for round stars every time.

        Ava F. ★★★★★

        Finally got this adapter to connect my camera to the SCT without any wobble—the threads are precise and smooth, no cross-threading issues. The construction feels solid, and it only took a few minutes to swap out my old setup.

        Eva ★★★★★

        This little adapter let me finally attach my ZWO camera to the scope without any wobble, and the threads engaged smoothly right out of the box. The precise machining makes a huge difference for keeping everything squared up during long exposures.
