The Celestron T Adapter for Nexstar 4SE Telescopes is a sturdy aluminum T Adapter for when 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 will need the appropriate T Ring for your camera body 93402 for Nikon 93419 for Canon EOS. First you remove the lens from your camera and attach the T ring in its place. As the T ring is camera brand specific, it will snap right on just like a lens. Next, remove the diagonal and visual back from the rear cell of your telescope and screw the Celestron T Adapter onto the rear cell threads until secure. Now, thread the T ring camera onto the T Adapter. 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.
