## Overview

The Celestron 93640 Universal Barlow and T-Adapter is a versatile 1.25-inch accessory that doubles your telescope’s magnification, converts it into a prime focus camera lens, and offers extended focal length options. Compatible with most 1.25” eyepieces and DSLR cameras (T-Ring sold separately), it’s designed for both visual observation and astrophotography, delivering sharp, detailed images of celestial and terrestrial subjects in a durable, stylish silver/black finish.

## Description

This 1. 25” accessory 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. The Universal Barlow and 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 and 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. 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.

Review: Love the Tring barlow - Perfect Dual-Purpose Accessory! The Celestron 93640 exceeded my expectations. As both a 2x Barlow and a T-adaptor for astrophotography, it’s incredibly versatile. The build quality feels solid and durable with a sleek silver/black finish, and it connects seamlessly to my telescope. Using it as a Barlow gives me sharp, detailed views of the moon and planets, and when paired with my DSLR it easily transforms into a reliable T-adaptor for capturing images. I love that I don’t need two separate accessories—this does both jobs perfectly. An excellent value and a must-have for anyone looking to expand their viewing and imaging capabilities!
Review: Works Great! - Works great and allows me to use my wide-angle eyepiece to zoom in when needed
