The Celestron 2x Barlow lens with T-Adaptor can be used three ways: as a 2X Barlow for visual use, as a prime focus T-adapter, or as a “Barlowed” T-adapter for double the magnification and the benefit of extra inward focus travel. Insert any 1.25” eyepiece into the chamber and you'll enjoy double the magnification, while retaining all the eye relief of the inserted eyepiece. The Celestron Universal Barlow and T-Adapter can also be used for prime focus photography, which means you use the telescope as a photographic lens.

The Celestron 2x Barlow lens with T-Adaptor

Using it for prime focus photography
Simply unscrew the bottom section of the unit to remove the Barlow and slide the chrome barrel into the telescope’s 1.25” focuser or adapter. Lock it firmly in place with the focuser or adapter thumbscrew. T-threads on the top of the adapter screw into a T-Ring (sold separately) that is designed to attach to the brand-specific mounting flange of your DSLR or SLR camera.

Please note that some telescopes, especially “fast” refractors and 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, adding the Barlow to the T-Adapter will allow the telescope to reach focus. In “Tele-Extended” mode, the Barlow doubles the focal length and f/ratio of your telescope, resulting in an image on the sensor or film plane that is twice the size of a prime focus image.

Prime focus and tele-extended photography are popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.
