Celestron 93515 - T-Adapters and T-Rings

25
T-Adapters
A T-Adapter allows you to attach your
35mm SLR camera to the prime focus of
your telescope or spotting scope. This
arrangement is used for terrestrial photogra-
phy and short exposure lunar and planetary
photography. It can also be used for long
exposure deep-sky photography when using
a separate guidescope.
Both a T-Adapter and T-Ring are required to
mount a camera to your instrument.
T-Adapters are available for the following
Celestron instruments — some instruments have built-in T-Adapters (see your
instruction manual):

T-Rings – 35mm
A T-Ring couples your 35mm camera body to a T-Adapter, Radial Guider or
Tele-Extender. This accessory is required if you want to do any type of photog-
raphy through a telescope or spotting scope. Each camera manufacturer has a
different mount, which requires a specific T-Ring, so Celestron offers a full line
of T-Rings.
To use a T-Ring, remove the diagonal and/or eyepiece from your telescope
(some models require use of an eyepiece — see your instruction manual). Then
you need only remove your normal camera lens, attach the proper T-Ring for
your camera, and mount the combination to the rear cell of your telescope or
spotting scope with a Celestron T-Adapter. Models available:
Canon [93413]
Canon EOS [93419]
Minolta [93400]
Minolta Maxxum [93418]
If you own an older camera with a thread mount, it will probably accept the
Pentax Universal Thread Mount T-Ring. If you have a new camera with a
bayonet mount not listed above (Ricoh, Cosina, etc.), it most likely accepts the
Pentax K-Universal Bayonet Mount T-Ring. Check your camera’s instruction
manual for more detailed information.
