## Overview

The Celestron 93640 Universal Barlow and T-Adapter is a compact, 3-in-1 telescope accessory that doubles magnification for visual use, enables prime focus DSLR photography, and offers tele-extended photography by combining both functions. Compatible with all 1.25” eyepieces and T-ring camera mounts (sold separately), it’s a lightweight, versatile tool designed to enhance both amateur and advanced astrophotography experiences.

## Description

Product 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: Really easy to use a must have for the price - I am very new to astronomy and hadn't heard of a Barlow Lens before but as a complete beginner, I think this is a must have. It's very cheap to buy and doubles the magnification of each eye piece which has so far provided some fantastic views of the moon and a couple of other bits. Prior to buying this, I spent a lot of time on the various forums doing research but the impression I get is that astronomy is one of those areas where everybody has an opinion on the various bits available and the people with more expertise can be quite critical to certain products that are in practice, absolutely fine for the beginner/novice. I think this product is a great price point, very good quality and unless you are significantly more experienced, is likely to do the job perfectly for you.

## Questions & Answers

**Q: can the barlow lens be used with eyepieces, or just with a camera?**
A: I have only used it with the camera ring and camera but it will I think double the power of any lens that you put in in.

**Q: Would this adapter work with s celestron astromaster 130eq?**
A: Yes, it should fit, assuming that the telescope eyepiece holder is a standard 1.25 inch one. If not, there are adapters from a 2 inch holder to a 1.25 inch fitting (there aren't very many other size eyepiece holders around). For photographic work you will need a "T-ring" to fit your camera and a suitable camera  (SLR or DSLR and one or two unusual fixed lens cameras).Regards,David Perkin.

**Q: how would I fit this to a 45 degree celestron scope model 52223?**
A: Sorry, you can not fit this barlow or different eyepiece on the Celestron 52223 spotting scope

**Q: i have a Fuji fine pix bridge camera will it work with this**
A: I don't know the Fuji camera but this device is intended for use on an SLR/DSLR using  an additional 'T'-Ring. It is unlikely to mount on a camera with a fixed lens as yours seems to be since there won't be a thread to mount the T-Ring on. For a camera with a built-in lens, you have to use an entirely different technique, called "afocal projection" looking through an eyepiece into the telescope with the camera focused at infinity. There are detailed accounts in astrophotography and astronomy books and online.Regards,David Perkin.
