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.

      Chloe ★★★★★

      The fit between this adapter and my AP2.7 threaded mount is absolutely perfect—no wobble, no play at all. Screwed on smoothly right out of the box, and my camera is now rigidly secured for imaging sessions. It's exactly the precision I needed for critical focus.

      Emma ★★★★★

      The threading on this adapter is incredibly precise—it screwed onto my AP2.7 mount without any wobble or cross-threading. My back focus distance is now spot-on, and I'm finally getting sharp stars across the entire frame.

      Leo Y. ★★★★★

      Finally got my camera setup properly snug with this adapter—the threads cut clean and mate perfectly with my focuser. No more tilt or flex, even with a heavy filter wheel hanging off the back.
