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.

        Brian R. ★★★★★

        Finally found a 3" adapter that actually fits my threaded focuser without cross-threading — the machined threads are smooth and precise. It let me attach my camera T-ring securely for prime focus astrophotography, and the connection feels solid even with a heavy DSLR hanging off it. Worth the extra

        Riley D. ★★★★★

        Threads engage smoothly and seat perfectly against my camera's T-ring without any wobble, which is exactly what I needed for my imaging train. The 3-inch length gives just enough reach to clear my filter wheel, and it's solidly built for the price.

        Benjamin ★★★★★

        Machined threads are dead-on, so the T-thread side seats flush with zero wobble. I’ve used it on three different camera setups now, and it’s the first adapter I haven’t had to shim or fuss with.
