Celestron T-Adapter, NexStar 4, C90 Mak & C130 Mak - 93635-A

Highlights

• 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 DSLR 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.  If you have an M48 T-ring, you'll need an M48 to M42 ring adapter.

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