Description

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. This sturdy T-Adaptor is the imaging (photographic) accessory to use to attach an SLR or DSLR camera to the rear cell threads of a Schmidt-Cassegrain telescope will allow you to do prime focus photography.

Using the Adaptor: For using a SLR/DSLR you will need the appropriate T-Ring for the camera body (e.g. #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 the diagonal and visual back from the rear cell of your telescope. Screw the Celestron T-Adaptor onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adaptor. That’s all there is to it. The camera is now using your telescope as a giant telephoto lens. The magnification will depend on the telescope’s focal length. For instance, a 300 mm camera lens is considered to be pretty powerful. If you are using an 8” SCT at prime focus, your telescope is a 2000 mm lens with a lot of light-gathering capability too!
