Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.
Celestron’s Universal T-Adaptor allows the connection of a DSLR/SLR camera body or other T-threaded imaging device to a telescope that has a 1.25” focuser or eyepiece adaptor installed. The T-Threads on the top of the Universal T-Adaptor screw into a T-Ring (sold separately) that is designed to attach to the brand-specific mounting flange of your DSLR/SLR camera. The barrel end of the T-Adaptor slides into the focuser, just like an eyepiece, and locks into place with the focuser or eyepiece adaptor thumbscrew.
Please note: some telescopes, especially “fast” refractors and most Newtonians, may not have enough focus travel to allow the photographic image to come to focus when used in prime focus mode. In these instances, we recommend using the Universal Barlow & T-Adaptor (#93640). This item will double the magnification, reducing the field of view, but “push the focus point out” and will allow the telescope to reach focus.
