Celestron 93640 1.25 Inch Universal Barlow and T-Adaptor, Silver/Black & 93402 T-Ring Adapter for Nikon Digital Cameras, Black

Celestron 93640 1.25 Inch Universal Barlow and T-Adaptor, Silver/Black Universal 31.7mm T-Adapter. Similar to #93625 but in addition includes an integral 2x Barlow lens which can be used visually or photographically If you’d 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: 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 & 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. Celestron 93402 T-Ring Adapter for Nikon Digital Cameras, Black A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Nikon SLR or DSLR camera body, the Celestron Nikon T-Ring is the one for you. In order to use the Nikon T-Ring, remove the lens from your camera, and attach the T-Ring in its place, just as you would if you were mounting a lens. The telescope side of the T-Ring has threads that will accept a variety of camera adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do. You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The #93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor, the Universal T-Adapter (#93625), with its 1-1/4” barrel insert, is available. There are also special T-Adapters for the EdgeHD optical system: one for the 8-inch EdgeHD (#93644) and one for the 9.25, 11, and 14-inch EdgeHD (#93646). Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. If you need extra magnification beyond that which your Schmidt-Cassegrain telescope provides, a Tele-Extender (#93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.
