Description

How do you adapt to your telescope?

Over the years, Optec has developed dozens of adapters and custom fittings for various telescopes and mounts. Our most common telescope adapters are based upon a circular dovetail mount in three different sizes. 

  • OPTEC-2400 mount - our standard 2.4-inch diameter circular dovetail mount
    • Telescope Adapters for the TCF-S and IFW
    • The OPTEC-2400 circular dovetail mount is used for the TCF-S focuser and IFW filter wheel to allow easy connections from most any telescope. If your scope or accessory is not listed, do not hesitate to call.
  • OPTEC-3600 mount - our larger, 3.6-inch diameter circular dovetail mount
    • Telescope Adapters for the TCF-S and IFW
    • The OPTEC-2400 circular dovetail mount is used for the TCF-S focuser and IFW filter wheel to allow easy connections from most any telescope. If your scope or accessory is not listed, do not hesitate to call.
  • OPTEC-4300 mount - our newest, 4.3-inch diameter circular dovetail mount
    • Telescope Adapters for the Gemini Focusing Rotator
    • The OPTEC-4300 circular dovetail mount has been specially made to accommodate certain OEM low-profile versions of the TCF 3-inch series focuser bodies. These flush mount adapters allow the 3-inch drawtube of the TCF-S3 to pass inside the adapter for reduced overall length.  The new Gemini Focusing Rotator also uses this same dovetail standard for both telescope and camera side connections.

Generally, the OPTEC-2400 mount can be used to attach our 2-inch accessories such as the TCF-S and IFW. Likewise, the OPTEC-3600 mount can be used to attach our 3-inch accessories such as the TCF-S3 or Pyxis 3". The OPTEC-4300 mount is reserved for certain OEM TCF-S3 focusers and the Gemini Focusing Rotator.

  • Threaded Telescope Adapters
    • Responding to recent requests for threaded adapters and fittings, Optec has introduced a new line of adapters and extension tubes designed around the Astro-Physics 2.7-inch thread specification and the new, larger Deep Sky Instruments DSI 3.5 thread spec.
      • AP 2.7-inch Telescope Adapters and Extensions
      • DSI 3.5-inch Telescope Adapters and Extensions

                  John ★★★★★

                  The machining on this dovetail adapter is precise—it fit snugly onto my mount with zero play. I paired it with a scope I was unsure about, and the connection feels rock solid during long exposures. Nice to have this kind of quality for a specific adaption like this.

                  Timothy I. ★★★★★

                  I was a bit worried about compatibility, but this adapter fits my focuser’s OPTEC-3600 threads perfectly and feels rock-solid. The machining on the dovetail side is clean and tight, no wobble at all.

                  Lucy ★★★★★

                  The machining on this adapter is flawless—threaded right onto my Optec focuser without any wobble. Solid aluminum construction gives me confidence it'll hold collimation for years.
