This Celestron T-Ring for Nikon F Mount SLR Camera is designed to work with virtually all modern Nikon SLR (or Digital SLR Cameras). Utilizing the F Mount, if your Nikon SLR is less than 30 years old, you can be almost certain that this will fit your camera.
Setting up is simple, simply attach the T-ring to your camera body via the Bayonet attachment (Just like your camera lens), screw that onto the T-Ring (Purchased Seperately) which should be attached to your telescope and you are good to go*. To take a picture, your camera will most likely have to be in Manual Mode as there is no aperture adjustment and focus will have to be done manually via the telescope's focus wheel. All you need to do is set the shutter speed and start taking pictures.
*T-Ring also attaches to the eyepiece of Celestron Ultima and Regal spotting scopes
