Diagonals: .96" and 11/4"
Celestron’s Erect Image Diagonals are an Amici
prism design. This design allows you to look into
the telescope at a 45° angle, at images that are
oriented properly, meaning the image is upright
and correct from left to right. Use of Celestron’s .96"
to 11/4" 45° Erect Image Diagonal on a telescope
equipped with .96" eyepieces means greater versatility. This diagonal will allow you to use 11/4" eyepieces, to obtain a larger field of view and better eye
relief. A 90° 11/4" Erect Image Diagonal is available
for those who prefer that angle.
A Star Diagonal lets you view objects that are at a
90° angle from the direction the telescope is
pointing, thereby allowing comfortable viewing
when the telescope is pointed at, or near, the zenith
(i.e. directly overhead). The resulting image is right
side up, but will be reversed from left to right.

Finderscopes are secondary scopes, used to help
locate objects in the main telescope. The larger
the finderscope, the more you’ll see, to an upper
limit of 50mm. Units larger than 50mm have
too narrow a field of view to be useful.
Finderscopes mount onto the main telescope
tube and are an invaluable tool in locating
objects for viewing.

spend more time observing and less time
setting up. The finderscope has an easy to use
cross hair reticle. For CG-4 and CG-5 mounts.
Eyepiece filters are an invaluable aid in lunar and planetary observing. They
reduce glare and light scattering, increase contrast through selective filtration,
increase definition and resolution, reduce irradiation and lessen eye fatigue.
Celestron’s filters are made of high quality, solid plane parallel glass with excellent homogeneity. They’re anti-reflection coated to prevent glaring and ghosting.
All eyepiece filters are threaded to fit Celestron’s, and most other manufacturer’s,
11/4" eyepieces, and offer a full 26mm clear aperture.
Celestron filters are mounted in black anodized aluminum cells with the Kodak
Wratten Series Number individually engraved, and come with a plastic case for
safe storage. The cells
of each filter are
double-threaded, so
they can be stacked
(piggybacked) in
various combinations.
This allows you to
create different color
combinations and
transmission characteristics, or to have
the same color
characteristic, but
with a lower transmission. When stacking color filters, the effective transmission of the combination
you create is equal to the product of the spectral transmission of each of the
filters used.
The effectiveness of the filters depends on several factors, including: the aperture
and focal length of the telescope, the magnification being used, and seeing
Following, you’ll find descriptions of all of Celestron’s eyepiece filters and what
you can expect from them in different viewing situations. Some of these filters
are available individually, and others are available in convenient four filter sets
Celestron has put together to affordably expand your range of observing options.
You’ll find the information on these filters arranged in the following color categories: Yellow, Orange, Red, Blue, Green and Violet. In each category, the information that applies to all of the filters within that color group is listed, then specific
information for each filter is broken out into a separate category, where applicable.
This way, you’ll know what to expect from each of Celestron’s color filters. At the
same time, you’ll become familiar with the astounding variety of enhancements
available through these simple accessories.

11/4" Polarizing Filter Set: – #93608
Ambient daylight is normally comprised of multiple
wavelengths of light, vibrating in multiple planes. The
Eyepiece Polarizing Filter Set transmits only light moving
along a specific plane, thereby increasing the contrast
between surfaces with different planar transmissions.
Generally, the polarization effect makes blue skies a
deeper blue, eliminates surface reflections and helps
reduce atmospheric haze.
The Polarizing Filter Set is intended for visual use. It’s particularly useful for reducing
glare while observing the moon, double stars, the planets and terrestrial subjects – all
without affecting the color of the object being observed.
The Filter Set is comprised of two filters that thread into either the eyepiece or the
filter adapter, which comes with the set. When one filter is used alone, you get 30%
light transmission. When both filters are used together, you can vary the degree of
transmission. By causing the amount of transmitted light to vary, the filters become,
in effect, a continuously variable neutral density filter. At
maximum density, the Polarizing Filter Set transmits only 5%
of entering light.
Skylight Filter/Dust Seal – #93621
If you were to use only one filter, Celestron’s Skylight
Filter/Dust Seal would be your most versatile choice. This
general purpose, Wratten #1A filter improves color saturation
and balance, increases visual and photographic contrast, helps
to decrease glare in lunar and planetary observing, and penetrates atmospheric haze.
It’s also an inexpensive way to protect your investment in quality optics. This filter
threads onto the rear cell of your Celestron C5, C8, C91/4, C11 or C14 telescope to
serve as an effective dust seal. By leaving the Skylight Filter/Dust Seal on when
removing or attaching other visual accessories, you prevent dust and other atmospheric contaminants from entering the rear of your telescope. Needless to say, it’s much
easier to clean a dusty filter than a dusty primary mirror, secondary mirror and
corrector plate.
The Skylight Filter/Dust Seal must be threaded onto the rear cell of the instrument
before any other accessory is installed. The female end attaches to the rear cell of the
C5, C8 and C91/4 telescopes and the reducer plate of the C11 and C14 telescopes. All
additional accessories mount onto the exterior/male threads.
Moon Filters
Celestron’s Moon Filters are economical eyepiece filters for
reducing the brightness of the moon and improving
contrast, so greater detail can be observed on the lunar
surface. The clear aperture is 21mm for the 11/4" filter and
10mm for the .96" filter. Transmission is about 18%.
11/4" Moon Filter [94119-A]
.96" Moon Filter (for Economy and SMA Series
eyepieces) [94119-B]
Solar Filters
Celestron’s Solar Skreen® solar filters
transmit .001% of visible light, allowing
direct observation of the sun. You can see
sunspots and the mottled areas known as
granules with these filters. In addition to
reducing the intensity of the sun’s visible
light, they also block 99.999% of invisible
infrared light, so you can observe the sun
in complete safety and comfort.
The material used to make these filters is a
strong, precision engineered, aluminized
Clockwise: #94162,
polyester film known as Mylar. Each filter
#94134, #94131, #94135
consists of two sheets of Mylar. A layer of
aluminum is vacuum-deposited on each of these pieces of Mylar. The two
coated surfaces are then placed against each other to protect them from
scratching and other abuses. The material is very thin, about .0003", which is
about one-tenth the thickness of a human hair. Mylar offers superior performance to thicker filters and is less expensive than conventional glass filters. In
addition, glass filters are subject to breakage whereas the mylar filters are more
Mylar is a very flexible substance by nature. In fact, when the Solar Skreen is
mounted in the filter cell, it will be quite wrinkled. Don’t be fooled by appearance, because the best resolution is obtained when the material is slightly
relaxed or wrinkled.
The color of the solar image will look different than it does with other filters.
The aluminum coating creates a solar image that’s a cool, pale blue color. A
more true color image can be obtained with the appropriate correction filter:
either #21 Orange or #23A Light Red.

LPR Filters
Light Pollution Reduction (LPR) Filters are
designed to selectively reduce the transmission
of certain wavelengths of light, specifically
those produced by artificial light. This
includes mercury, and both high and low
pressure sodium vapor lights. In addition, they
block unwanted natural light caused by
neutral oxygen emission in our atmosphere
(i.e. sky glow). As a result, Celestron LPR
Filters darken the background sky, making
deep-sky observation and photography of
nebulae, star clusters and galaxies possible
from urban areas. LPR Filters are not used for
lunar, planetary or terrestrial photography.
While blocking unwanted light, Celestron LPR Filters permit the transmission of more desirable wavelengths. The wavelengths
included are hydrogen alpha,
hydrogen beta, doubly ionized
oxygen and singly ionized
nitrogen. This will improve your
viewing of emission nebulae,
both from urban and rural
settings. Some examples of
objects that will show improved
contrast are: the Orion Nebula,
the Rosette Nebula, the North
American Nebula, the Veil
Nebula and the Helix Nebula.
The latest generation of
Celestron LPR Filters is made of
high quality, flat, polished
optical glass. These units are not
laminated! With over 40 layers
of coating, these filters are stateof-the-art. They’re also protected with a broadband anti-reflection coating to
prevent ghosting and to improve contrast. They provide superior performance and contrast over competitive models.
LPR Filter – for 11/4" eyepieces [#94126A]
LPR Filter – for rear cell of Celestron’s C5, C8 or C91/4 [#94127A]
(Fits on the reducer plate of C11 and C14 telescopes.)
To allow automatic tracking of celestial objects,
Celestron offers several motor drives. All models
include a hand controller, which makes observing more fun as it makes centering objects
much easier. In addition, the hand controller
can be used as a drive corrector for long exposure celestial photography.
Economy Models
These models are single axis (R.A.), DC motor
drives. They are powered by four D-cell batteries
(not included). 2x and 4x sidereal speeds are
available through the included hand controller.
Model #93515 — MDCG-3 (for Firstscope 80s and 114s)
Model #93517 — MDCG-4 (for CG-4 mounts)
Model #93518 — MDCG-5 (for CG-5 mounts)
Deluxe Model — Polaris Motor Drive System – #93820-C
This dual axis motor drive, with drive corrector capabilities, is designed for
Celestron’s CG-5 and GP mounts. It precisely controls the telescope’s
tracking speed during long, timed exposures of celestial objects, producing
the best possible image sharpness. Precision drive correctors are a must for
those with a serious interest in astrophotography or
CCD imaging. Three speeds are available — (1x)
sidereal, 1.3x for guiding and 6x for centering.
This precision, state-of-the-art DC motor drive
operates on a 9 volt battery (not included). The hand
controller module is very compact and fits easily in
the palm of your hand. Motors for both axes are
included, along with brackets, clutches and hardware. Made in the USA.
Declination Motors
Celestron’s Declination Motor attaches to your
telescope’s manual declination control to offer
smooth, vibration-free control in declination.
Run by the telescope’s power supply, it plugs
directly into the drive base and is controlled by
two buttons, for north and south declination
movement. Highly useful for observing, and a
must for astrophotography.

Guiding (or reticle) eyepieces are mandatory for guided
astrophotography. They keep a guide star stationary
during long exposures to avoid star trailing. #94169 and
#94170 require an illuminator — choose from models
#60001 and #60011.
12mm Kellner Reticle Eyepiece: 11/4" –
The reticle pattern is a .0075" spaced double line system.
The optics are fully coated and offer good eye relief. This
type of reticle pattern allows you to position the guide star
in the middle square or at the intersection of two lines,
whichever is easier for you. It has a 42° apparent field of view.
Clockwise: #94171,
#94169, #94170
10mm Plössl Reticle Eyepiece: 11/4" – #94169
This five element guiding eyepiece has the same pattern as the Kellner
design above. The optics are multi-coated for increased contrast and
have long eye relief. The high power is ideal for guiding and it has a
50° apparent field of view.
Micro Guide Eyepiece: 11/4" – #94171
This multi-function guiding eyepiece features a laseretched reticle with a built-in, battery illuminator. The
eyepiece is a multicoated 12.5mm Abbe (four element)
Orthoscopic. Usage possibilities include: direct guiding on
stars outside the center of the field of view; greatly
improved off-axis guiding to capture much fainter, sharply
focused guide stars without reducing limiting magnitude;
and measuring position angles and separation of double
The Micro Guide Eyepiece is totally free of internal
reflections and offers sufficient eye relief for the reticle to be viewed easily, even with
eyeglasses. Its finely etched micrometer scale has gradations 50 microns apart and 15
microns wide. Included are: the eyepiece, built-in cordless illuminator with adjustable
brightness control, batteries and instructions. The apparent field of view is 42°.
Standard Illuminator — #60011
An adjustable brightness red LED which can be used in
Celestron (and most other manufacturers) guiding eyepieces
and the Polaris finderscope.
Pulstar Illuminator – #60001
Celestron’s Pulstar Illuminator is an innovative new design that takes pulsing illuminators to a new level of performance. Not only does it allow for easy adjustment of
pulsing rates and timing intervals, it also has an adjustable brightness level and
important automatic shutdown feature to save you the frustration of a dead battery.
The Pulstar Illuminator improves contrast while locating and
using guide stars for CCD imaging and astrophotography, and
helps in locating objects during viewing sessions. Fits most
reticle eyepieces and Polaris finderscopes. Battery is included.
Made in the USA.
Reducer/Corrector f/6.3 – #94175
This combination focal reducer and field corrector lens
accessory works with all Celestron C5, C8, C91/4 , 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, C91/4 and C11 telescopes and f/7 for the C14
If offers wide fields of view with any SchmidtCassegrain 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
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, C91/4, C11 and C14 telescopes and comes
with a unique prism angle adjustment screw. It
must be used with a guiding eyepiece, camera TRing 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 guiders.
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).
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.
Focus Motor for Ultima 91/4 , 11 and
2000 [94143]
Focus Motor for all C8s and C11s with
separate hand control [94142]
60mm Guidescope – #22212
A 60mm Guidescope of 700mm focal
length. Comes standard with a 11/4" mirror
diagonal and 5x24 finderscope. Includes
hardware and tube rings to mount it onto a
C8 telescope. A necessary accessory for
guiding longer exposures.
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
The Counterweight Bar Assembly is a metal rod that runs the length of the
telescope tube. It attaches to both the front and
rear cells. Once the Bar Assembly is in place,
counterweights can be attached to it and moved
along its length, as well as perpendicular to it, for
better dynamic balancing. Each Counterweight
Bar Assembly comes with mounting hardware and
one 2.5 lb. weight.
Counterweight Bar Assembly – 8" [94191]
Counterweight Bar Assembly – 91/4" [94196]
Counterweight Bar Assembly – 11" [94192]
Extra Weight – 2.5 lbs. [94193]
Extra Weight – 5 lbs. [94194]
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.
Dewstar Lens Shade – C8 [94017]
Lens Shade – Ultima® 2000 and C8 [94019]
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):
#93625—Universal 11/4" T-Adapter. Fits (drop in style) any type of telescope that uses a 11/4" focuser or
visual back.
#93640—Universal 11/4" T-Adapter. Similar to #93625 but in addition includes an integral 2x Barlow
lens which can be used visually or photographically.
#93632—Universal .96" T-Adapter. Fits (drop in style) any type of telescope that uses a .96" focuser.
#93634-A—for Firstscope 80AZ and EQ models. Also fits various older style Celestron refractors and
#93633-A—for all Schmidt-Cassegrains. It threads onto the rear cell.
#93635-A—for all C90 Spotting Scopes.
#94177—required when using the Radial Guider for CCD imaging.
#93638—for Nature Zoom Spotters.
#93628—for Pro Zoom Spotters.
#93627—for Wildlife Zoom Spotters.
#1836—for Ultima Spotters.

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:
Canon [93413]
Canon EOS [93419]
Minolta [93400]
Minolta Maxxum [93418]
Nikon [93402]
Olympus [93414]
Pentax – Universal M42 Thread Mount [93401]
Pentax K – Universal Bayonet Mount [93403]
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 TeleExtender 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 TeleExtender.
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 Tele35mm
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.
Visual Back
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, C9 1/4", 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
Piggyback Counterpoise – 5" [93603]
Piggyback Mount – 8", 91/4", 11", 14" [93598]
T-C 16mm Adapter – #93636
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
Digital Setting Circles: Advanced Astro

Peterson First Guides® — Astronomy — #93728
A simplified field guide to the stars, planets and the universe. A great road map
for those starting out in
Peterson First Guides® —
Birds — #93731
A simplified field guide to the
common birds of North
America. Very easy to understand, especially for beginners.
A simple and inexpensive tool for all levels of observers,
from naked eye viewers to users of highly sophisticated
telescopes. The Celestron Planisphere makes it easy to
locate stars for observing and is a great planet finder as
well. A map of the night sky, oriented by month and
day, rotates within a depiction of the 24 hours of the
day, to display exactly which stars and planets will be
visible at any given time. Ingeniously simple to use, yet
quite effective. Made of durable materials and coated for
added protection.
The Celestron Planisphere comes in three different
models, to match the latitude from which you’re
For 20° to 40° latitude [93720-30]
For 30° to 50° latitude [93720-40]
For 40° to 60° latitude [93720-50]
CD-ROM – #93700
Celestron and Software Bisque have teamed up to present
a comprehensive CD-ROM called The Sky™ Level 1 – for
Celestron. A computerized sky map that features a 10,000
object database, 75 color images, horizontal projection,
custom sky chart printing, and zoom capability. A fun,
useful and educational product. PC format.
Sky Maps – #93722
Celestron Sky Maps are the ideal teaching guide for learning the night sky. You
wouldn’t set off on a road trip without a road map, and you don’t need to try to
navigate the night sky without a map either. Even if you already know your way
around the major constellations, these maps can help you locate all kinds of fascinating objects.
The front cover has a specially designed
luminous planisphere that rotates to
simulate the seasonal progression of
celestial objects through the sky. When the
planisphere is pre-exposed to light, star
positions glow brightly against a dark
background, mimicking actual constellations. More than a thousand stars and deepsky objects are listed and charted. The
illustrated reference section provides basic
information and the visual characteristics of
various types of stars, nebulae and galaxies.
The maps measure 133/4" x 111/2" and are
printed on a heavyweight, moisture
resistant card stock. The pages have a special comb binding so they can lay flat or be
folded over.
Enjoy your telescope in a completely new and fascinating way — use your brain to
its full capacity rather than speculating on the next, larger size telescope.
The Stereo Binocular Viewer (#93690) allows you to adapt two eyepieces to the
telescope for simultaneous viewing (i.e., like binoculars). The result: a fantastic three
dimensional effect when observing many celestial objects. The Stereo Binocular
Viewer greatly improves contrast and definition on lunar, planetary and solar subject
matter as well as on deep sky objects.
Using both eyes to view through a telescope is a new, relaxed and thrilling way to at
last enjoy your observing time. When both eyes are open, your eye muscles are
relaxed and you do not suffer from eyestrain.
To demonstrate just one of the effects you will see, compare an eye chart when
examining your eyes. Cover one eye and read the chart to the smallest line you can
see clearly. Now remove the cover over the eye, relax for a few seconds and then
examine the chart with both eyes open — you can see more detail than with one
eye. In addition, the brain corrects for small defects (aberrations) of the eyes when
given the information from both eyes.
Beyond a 50 foot distance, pupils are nearly parallel and prevent real stereoscopic
viewing. However, since our brain “knows” (due to near distance experience), we
identify distant objects as three dimensional. The more experienced the observer, the
more this effect will be apparent.
The optics are precision aligned and MgF2 coated. Interpupillary adjustment reaches
from 53mm to 76mm. The optical head has a 60° viewing angle for a comfortable
viewing position. Full 360° head rotation is provided, together with 2" sleeve and
11/4" drawtube to fit 2" Focuser and 11/4" Visual Backs of all Schmidt-Cassegrains —
and also Focusers of Refractors.
The removable 11/4" drawtube features a camera T-2 thread on the Binocular side and
11/4" Filter Thread on the entrance side, to accept Celestron 11/4" Eyepiece Filters.
Utilizes 11/4" eyepieces (not included). Must use two eyepieces of equal focal length
and design type. Made in Germany.
Photographic/Video Tripod – #93596
For use with photographic and visual instruments fitted with a
standard 1/4" x 20 threaded hole. The Photo Tripod provides
stable support for video cameras, telephoto lenses, spotting
scopes and binoculars. This tripod boasts a number of deluxe
features, including: oil fluid pan head, peg for video camera
attachment, quick release pan head, adjustable aluminum legs,
adjustable central column, extendible length vertical pan
handle, and retractable metal feet for added traction on a
variety of surfaces. New clamp-style leg locks. Both lightweight
and reliable.
Alt-Az Photo Tripod Mount – #91533-A
This heavy-duty mount is perfect for cameras with large
telephoto lenses, and for spotting scopes and binoculars. If you
already own a small telescope mount and are interested in one
offering greater stability, the Alt-Az is an ideal upgrade. The
adjustable wood tripod comes with two slow motion cables and
is equipped with a 1/4" x 20 photo head. It’s the same mount
that’s supplied with Celestron’s Firstscope 80AZ telescope.
Slow Motion Controls for Photographic
Have you ever tried to use a powerful telephoto lens or
spotting scope with a standard photographic tripod? If so, you know that it isn’t
easy. Try to adjust the position of the lens to follow a target and you’ll discover that
just touching the lens can cause so much vibration, it can be difficult to even find the
target, let alone center it. By using Celestron’s Slow Motion Controls between your
lens/spotting scope and your photographic tripod, you gain accurate slow motion
adjustment in both elevation and azimuth (i.e. up/down
and left/right).
The Tripod Slow Motion Controls fit on top of any
standard photo tripod and have a large stable base with a
standard 1/4" x 20 mounting screw to attach a camera,
telephoto lens, spotting scope or binocular. Makes bird
watching and telephotography easy!
The deluxe model has ultra smooth controls and virtually
no backlash.

A very sturdy tripod designed for tabletop or platform use,
where portability is important. It has rugged, metal construction
and features slow motion controls for fine tuning when
acquiring a target object. Works well with most spotting scopes
and binoculars with a 1/4" x 20 adapter. It weighs under two
pounds and has a height adjustment range of 12" to 17".
Lightweight Field Tripod – #93591-A
Designed for Celestron’s C5 telescope, this rigid,
metal tripod weighs less than 10 lbs. and is very
compact when folded up. It’s great for traveling.
It can be used with the Celestar 8 telescope
when high portability is required.
An optional accessory tray (#93594) is available
for this tripod. Not only is the tray handy for
small accessories, but it also enhances the
overall rigidity of the tripod.
Adjustable 8" Tripod – #93499
This deluxe metal tripod has fully adjustable
legs with all metal clamps for positive
height adjustment. It’s designed for
Celestron’s C8, C91/4 and C11 telescopes,
and also makes a very stable and sturdy
platform for the C5+ telescope. A new leg
support has been added for additional
stability and the 2" diameter legs provide
excellent damping.
Vibration Suppression Pads –
Telescope and spotting scope vibration is
caused by windy conditions, an unsteady mount or tripod or even an
accidental bump to the instrument, and results in reduced image quality.
Celestron’s set of three Vibration Suppression Pads will reduce vibration time
by almost 100% and decrease vibration amplitude. The pads fit between the
bottom of the tripod legs
and the ground, a simple
and functional solution to
the problem of image
disturbance. They work on
any surface: grass, dirt,
concrete, asphalt, wood,
etc., for both telescopes
and spotting scopes.
For optimal performance in astronomical observing
that involves setting circles or motorized tracking,
Celestron’s telescopes with a fork mount and motor
drive must be mounted on an Equatorial Wedge. The
wedge allows you to tilt the telescope so that its polar
axis (R.A. axis) is parallel to the earth’s axis.
The angle of tilt will depend on your latitude when
the telescope is level. The angle between the horizon
level and the polar axis will equal your latitude when
the telescope’s axis is parallel with that of the earth’s.
Once properly mounted and adjusted on the wedge,
the telescope is said to be equatorially mounted and
its setting circles can be used to locate deep-sky
