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.
