  • This Celestron T-Adapter connects a DSLR camera to a NexStar 4SE or C90 spotting scope for prime focus photography.
  • Threads onto the rear cell for secure, wiggle-free connection.
  • T-threads accept camera brand specific T-Ring (sold separately).

This sturdy aluminum T-Adapter is the accessory of choice if you’d like to attach an SLR or DSLR camera to the smaller rear cell threads of a Celestron NexStar 4SE telescope or C90 spotting scope for prime focus photography. 

To get started, you’ll need the appropriate T-Ring for your camera body  (#93402 for Nikon & #93419 for Canon EOS).  Remove the lens from your camera and attach the T-ring in its place.  Since the T-ring is camera-brand specific, it will snap right on just like a lens.  Next, remove any accessories from the rear cell of your telescope.  Screw the Celestron NexStar 4SE T-Adapter onto the rear cell threads until secure.  Now, thread the T-ring & camera onto the T-Adapter.  That’s all there is to it.  The camera is now using your telescope as a telephoto lens.

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

Note: Your camera will need to be in fully manual exposure mode, although some brands of camera may also work in aperture-priority autoexposure mode.  Additionally, if there is a switch on the camera which chooses the focus mode, that switch must indicate manual focusing.
