## Overview

The Celestron 93640 Universal Barlow and T-Adapter is a versatile 3-in-1 telescope accessory that doubles magnification on 1.25-inch eyepieces, converts your telescope into a telephoto lens for prime focus photography, and integrates seamlessly with DSLR/SLR cameras via T-threads. Lightweight and compact, it enhances both visual observing and astrophotography with professional-grade precision.

## Description

Celestron 93640 Universal Barlow and T-Adapter 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. It can be used as a 2X Barlow right out of the box. Insert any 1.25-inch eyepiece into the chamber and you’ll enjoy double the magnification, while retaining all the eye relief of the inserted eyepiece. It 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-inch 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. 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
*by J***5 on 20 August 2025*

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!
