| Reducer/Corrector f/6.3 – #94175 | |
 Price $145 |
This combination
focal reducer and field corrector lens accessory works with all Celestron C5, C8, C9¼,
C11 and C14 telescopes. This clever accessory makes it possible to have a dual focal ratio
instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C8,
C9¼ and C11 telescopes and f/7 for the C14 telescope. If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.
|
| Celestron doesn’t offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically. |
| Radial Guider – #94176 | |
 Price $119 |
Specifically for
use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain
telescopes, the Radial Guider is compact and sleek in design. This accessory makes it
possible to simultaneously photograph and guide through the optical tube assembly of your
telescope. The Radial Guider also eliminates the problem of differential flexure, because
you’re both guiding and photographing through the telescope. The Radial Guider is compatible with Celestron’s C5, C8, C9¼,
C11 and C14 telescopes and comes with a unique prism angle adjustment screw. It must be
used with a guiding eyepiece, camera T-Ring and drive corrector (dual axis preferred).
Primarily for use with catadioptric telescopes, but also works on refractor telescopes
having adequate back focus. |
| This guider is a tremendous improvement over conventional off-axis guilders. Not only is the angle of the prism tunable, but it also maintains a fixed rigid camera orientation while still offering users the freedom to move the guiding eyepiece radially about 135°. |
| Hand Controller – #28983 | |
 |
For use with the C5 + and Celestar 8, both for
astrophotography and CCD imaging. It’s also great for observing, where it serves to
make centering objects easier. Provides easy centering and guiding on both axes. (Requires
declination motor for use of the declination axis). Price $79 |
| Focus Motors | |
 |
These motors allow you to focus the telescope
electronically, instead of manually. The motorized focuser eliminates the possibility of
bumping or shaking the telescope when focusing. The motor speed is variable, to make fine
focusing a snap. |

| Counterweights | |
 |
Using accessories
such as cameras, Lens Shades, Tele-Extenders and the 2" Diagonal will affect the
balance of your Celestron Schmidt-Cassegrain telescope. Counterweights restore proper
balance, increasing ease in handling and improved tracking accuracy. You don’t need perfect balance to operate your telescope. In fact, it’s not always possible to achieve perfect balance with fixed-position weights. All you need to do is reduce, or eliminate, swing when R.A. and DEC locks are released. Celestron counterweights help you achieve the desired balance and stability with ease. Counterweight Bar Assemblies |
|
| Counterweight Set:
Ultima® 2000 – #94190 The standard set of weights works well when using standard accessories, but when adding heavier optional accessories, you’ll require this optional set of weights to achieve proper balance. The set contains one large and four small weights. |
| Lens Shades/Dew Caps | |
 |
A Lens Shade/Dew
Cap is a tube, of approximately the same diameter as your telescope tube, designed to fit
on the front end of the telescope to reduce the amount of dew that builds up on the
corrector plate. It also serves as a Len Shade by preventing stray light from falling on
the corrector plate, which greatly improves contrast. The C8 Lens Shades are made of rugged plastic, and have a tapered design (other designs made with different materials cause vignetting). They snap easily onto the front cell of all of Celestron’s C8 telescopes. |
|
| 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 photography 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 photography 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: |

|
| 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. |
| Deluxe Tele-Extender – #93643 | |
 |
The Deluxe Tele-Extender for Schmidt-Cassegrain telescopes is a hollow tube that allows you to attach a camera to your telescope, with an eyepiece installed. By using the Deluxe Tele-Extender in combination with an eyepiece, you can increase your instrument’s effective focal length to well over 10,000mm! And this corresponds with a matching increase in image size. This technique is known as eyepiece projection photography. The following formula can be used to determine approximate effective focal length: |
 |
EFL = Telescope
focal length/Eyepiece focal length x DF (the distance from the center of the eyepiece to
the film). The Deluxe Tele-Extender is used for high-power lunar, solar and planetary photography as well as for extreme terrestrial photography. It fits over the telescope’s eyepiece (even large eyepieces such as those in Celestron’s Ultima line), and connects to the visual back of the telescope. Optional counterweights will be necessary to properly balance the telescope when using the Tele-Extender. |
| To use the Deluxe Tele-Extender, remove the
diagonal from your telescope and insert an eyepiece directly into the visual back. Place
the Tele-Extender over both the eyepiece and the visual back, then attach your 35mm SLR
camera to the back of the Tele-Extender, using a T-Ring. The Tele-Extender’s built-in
safety device will help prevent your eyepiece from becoming accidentally dislodged. There are a few things to keep in mind when using this accessory. First, the image you’ll see through your camera’s viewfinder will be upside-down. Secondly, due to the extremely high magnifying effect afforded by this accessory, extra care to prevent camera and telescope vibration, accurate polar alignment and use under good seeing conditions will all assist you in capturing high quality images. |

| Piggyback Mounts | |
 |
Celestron’s
Piggyback Mounts are a great accessory for all observers interested in deep-sky
astrophotography, particularly beginners. These mounts allow you to attach your camera,
with its lens, to either the top or side of the telescope, making it possible to shoot
with a normal or wide angle lens while guiding through the telescope. One model fits the C8, C9¼", C11 and C14 telescopes and mounts to the rear cell of the telescope. The C5 model includes a weight set and mounting hardware to attach the camera to the telescope’s piggyback platform. |
|
| T-C 16mm Adapter – #93636 |
 Price $45.00 |
This valuable
adapter converts video cameras, (or 16mm film cameras) with removable lenses from the
standard "C-mount" thread, to the larger T-thread used in still cameras. Thus,
any of these cameras can be converted for use with a telescope. To adapt a C-mount camera for use with a Celestron instrument, first thread the T-C Adapter onto the camera, next thread a T-Adapter onto the T-C Adapter, and last, thread this assembly onto the rear cell of your Celestron instrument. Please note that some film and video cameras use standard
still camera lenses, and therefore use a normal T-Adapter and T-Ring. Check your
camera’s instruction manual for more detailed information. |
