The Universal Barlow & T-Adapter can be used as a 2X Barlow right out of the box. 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 & T-Adapter can also be used for prime focus photography, which means you use the telescope as a photographic lens—a very big photographic lens! Just 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.
