Celestron Universal Barlow & T-Adapter (93640)
If you would like some flexibility in your astrophotography set-up, consider the Celestron Universal Barlow & T-Adapter (93640). This 1.25" accessory can be used three ways:
- 2X Barlow: For visual use, insert any 1.25" eyepiece to enjoy double the magnification while retaining all the eye relief.
- Prime Focus T-Adapter: Use the telescope as a photographic lens by removing the Barlow and attaching the chrome barrel to the telescope's 1.25" focuser.
- Barlowed T-Adapter: Combines the Barlow with the T-Adapter for double the magnification and extra inward focus travel.
Note that some telescopes, especially fast refractors and Newtonians, may not have enough focus travel for prime focus mode. In such cases, adding the Barlow allows the telescope to reach focus. In Tele-Extended mode, the Barlow doubles the focal length and f/ratio, 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 and celestial objects like the Moon.
The Celestron Universal Barlow & T-Adapter is three accessories in one:
- 2X Barlow for visual observing.
- Prime Focus Photography to transform your telescope into a giant telephoto lens.
- Tele-Extended Photography for double the magnification of prime focus mode.
T-threads accept camera brand specific T-Ring (sold separately).
