and 2" models. This is a highly economical traditional
Plössl optical design series.
The 1 1/4" E-Lux is a 4-element Plössl with features
that maximize it's performance at a very economical price.
Features of this series include fully coated lenses (every
air to glass surface is coated with anti-reflective coatings),
eyepiece cups to reduce stray light, and each model is threaded
for use with eyepiece filters.
The 2" E-Lux class is the best value 2"
eyepieces on the market. It is a 3-element fully
multicoated optical design (every air to glass surface is
coated with several layers of high quality anti-reflective
coatings). The 2" E-Lux provides a wider field of view
and longer eye relief than

you are looking to move up to a higher quality eyepiece
the Omni series provides more enhanced features in a wider
selection of focal lengths. Celestron designed this series
with the finer points in mind so you, the user, can benefit
from the features that make this series unique. The Omni
is a 4 -element premium symmetrical Plössl optical
design. Features include blackened lens edges to minimize
internal reflection and maximize contrast, multi-layer
coating group on each lens surface to maximize
light transmission and contrast, and each Omni goes through
a two-step anodizing process to prevent reflection from
the top eyepiece barrel, unlike most other manufactures
who use reflective surfaces. Threaded barrels accept 1-1/4"
Celestron thread-in filters.
Series 1 1/4"
you are looking for an eyepiece that excels for planetary
viewing, then Celestron’s X-Cel offers the unique
features you are looking for. A 6-element fully
multi-coated optical design, the X-Cel utilizes
extra low dispersion (ED) glass on its most highly curved
surfaces, to minimize chromatic aberration that can hinder
sharp planetary views. With a wide 55° apparent field
of view, and a large 25mm clear aperture the X-Cel is one
of the most comfortable eyepieces to use. Every X-Cel eyepiece
is parfocal with each other, meaning little or no focusing
is needed when changing from low to high power. The X-Cel
comes with soft rubber eyecups and a durable plastic case.
In addition, if you are an eyeglass wearer, you will enjoy
the 20mm eye relief available on each of the X-Cel focal
lengths. Threaded barrels accept 1-1/4" Celestron thread-in
Series 1 1/4"
Rated as best in their class by Sky and Telescope magazine,
the Ultima eyepieces use a 5-element hybrid optical design.
They feature long eye relief and a wide field, and each
air-to-glass surface is fully multicoated
to enhance contrast levels. These special eyepieces are
computer designed to keep visual aberrations to an absolute
minimum. They virtually eliminate the following aberrations:
spherical, color, field curvature, coma, astigmatism, distortion
and spherical distortion of the exit pupil. The inside surfaces
and edges of all lenses are blackened, to keep out reflected
light. Outside surfaces are flat black, with rubber grips
for secure handling. Rubber eyecups are included both for
comfortable use and to keep out extraneous light. Threaded
barrels accept Celestron 1-1/4" thread-in filters.
Lens and barrel caps are included for safe storage.
Series 1 1/4", 2"
These are Celestron’s top-of-the-line eyepieces. As
an extension of the popular Ultima line, the Axiom’s
offer a wider field of view in both 1.25” and 2”
barrel sizes. All Axiom oculars feature a 7-element design,
to give you tack sharp star images across its extra wide,
70° apparent field of view*. All are fully multicoated
with extra large pop-up eyecups to block unwanted stray
light. Like the Ultima series, the Axiom optical design
minimizes the following aberrations: spherical, color, field
curvature, coma, astigmatism, distortion and spherical distortion
of the exit pupil. The edges of the optical elements are
blackened to minimize internal reflections and increase

The Celestron Cheshire Collimation Eyepiece is ideal for
precise collimation of Newtonians and helpful for aligning
Schmidt-Cassegrains. This special eyepiece fits into 1¼"
focusers or diagonals. Alignment is easy using the small
opening on one end and thin cross hairs at the other end.
The collimation eyepiece is more accurate than the simple
Micro Guide Eyepiece (12.5mm) 1-1/4"
This multi-function guiding eyepiece features a laser-etched
reticle with a built-in battery illuminator. The eyepiece
is a multicoated 12.5mm Abbe (4-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 stars.
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°
Plössl Reticle Eyepiece 1-1/4"
(or reticle) eyepieces are mandatory for guided astrophotography.
They keep a guide star stationary during long exposures
to avoid star trailing. This 5-element guiding eyepiece
has a reticle pattern that is a .0075" double spaced
line system. The
optics are multicoated for increased contrast
and have long eye relief. The high power is ideal for guiding
and it has a 50° apparent field of view. 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. An optional illuminator is required.
Barlow lenses offer an easy, economical way
to increase the magnification range of your eyepieces, and
Celestron carries two of these highly useful lenses. A Barlow
lens doubles the magnifying power of your eyepiece by doubling
its effective focal length. For example, an 18mm eyepiece
used with a 2x Barlow lens would have the magnifying power
of a 9mm eyepiece. It’s like having two eyepieces
in one! If you’re looking for an affordable way to
achieve high-power viewing of the moon and planets, double
stars and even close-up views of terrestrial subjects, a
Barlow lens is the answer. Barlow lenses mount into either
your telescope’s focuser or visual back.
is a high quality 2x Barlow that doubles the magnification
of all 1.25" eyepieces. This economically priced Barlow
has great features like, low profile, 2-element fully-multicoated
optical design and blacked lens edges.
Ultima Barlow lens is, without doubt, the #1 choice among
amateur astronomers who want the best performance from their
optics. The Ultima Series Barlow (2x - 1-1/4") is an
air-spaced, 3-element apochromatic design
with a 27mm clear aperture. This lens features a very high
quality, fully multicoated design. Amazingly

& Filter Kit
The Eyepiece and Filter Kit (#94303) contains:
• Five Superior Grade Plössl Eyepieces - 1.25”
— 4-element design with a 52° AFOV (32mm has 44°
) — Superb color resolution, edge sharpness and clarity.
All eyepieces are fully multi-coated for maximum contrast
and resolution. Supplied are a 4mm,6mm, 9mm, 15mm, and 32mm.
• Barlow Lens - 2x 1.25”— Compliments
the Plössl eyepieces in this kit and gives you a total
of ten power combinations. High grade glass optics with
fully multicoated lenses are used so there is no degradation
• Six Colored Eyepiece(Lunar & Planetary) Filters
- 1.25” — Included are Kodak Wratten #12, #21,
#25, #56, #58A, and #80A. Since you have all the eyepieces
necessary to study the planets and moon in detail, these
filters will greatly enhance your enjoyment of our solar
• Moon Filter - 1.25” — A neutral density
filter which allows you maximum enjoyment of the moon especially
during the brighter phases.
• Aluminum Carrying Case — This sturdy and well-built
case fits all of the above items in the die-cut foam interior
and has room for additional accessories.
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 color filters are mounted in black anodized aluminum
cells with the Kodak Wratten Series Number individually
engraved, and come available in 4 assorted kits packed in
plastic cases. 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 conditions.
This is our newest high quality filter that eliminates most
color aberration inherent in achromatic refractor telescopes.
The filter also reduces your view of the blue hue around
lunar and planetary subjects. Features multi-layer coatings
for 95% transmission.
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
LPR Filter (Model A - for 2" eyepieces)
LPR Filter (Model A - for 1-1/4" eyepieces)
While blocking unwanted light, Celestron LPR Filters permit
the transmission of more desirable wave-lengths. 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.
Moon Filter - 1-1/4"
Celestron’s Moon Filter is an economical eyepiece
filter 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 and the transmission
is about 18%.
Filter Set 1-1/4"
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
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, C9
1/4, 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 C9 1/4 telescopes and the reducer plate of the
C11 and C14 telescopes. All additional accessories mount
onto the exterior/male threads.
Celestron Solar Filters are made with Baader Astro Solar™
Safety Film. Far superior than any existing glass, Mylar
or polymer filters, they lead to brighter, sharper, and
higher contrast images.
Enter the new millennium with the finest solar filters available.
Astro Solar™ Safety Film is clear and homogenous and
attains the optical performance of high quality plane-parallel
glass filters—it is diffraction limited! Double-sided
metal coatings have uniform density and good color balance
across the entire field ensuring razor sharp images from
edge to edge.
The Sun appears in its “real ”color —neutral
white, not blue or orange ,and the sky adjacent to the solar
limb is jet black.
You can see detail in sunspots, bright faculae near the
limb and the mottled areas known as granules with these
filters. The Sun offers constant changes and will keep your
observing interesting and fun. Even small aperture telescopes
can enjoy features of the Sun.
The Astro Solar™ film is completely safe and durable
(won‘t break like glass if dropped). Its rating is
ND-5 which means that the film transmits 1/100,000 of visible
light (.001%) while reflecting (blocking) 99.999%of unwanted
light. The film absorbs all ultraviolet rays while coating
reflects infrared light rendering both absolutely harmless.
For added assurance, Baader Astro Solar™ film has
been declared safe for direct solar viewing by the German
National Bureau of Standards for eye safety.
Celestron has previously manufactured high quality, plane-parallel
glass solar filters (unlike today ’s glass filters
which generally are poor in quality with reduced contrast).
Celestron has offered Mylar solar filters (they were the
best previously available) but they suffer from a lot of
scattered light and false color. Polymer filters suffer
from not only scattered light but also have reduced sharpness
and contrast due to their increased thickness. So, “we‘ve
been there and done that” and after all these years
are now offering the finest solar filters available for
observing. Each is mounted in a durable ABS or rubber cell
that won‘t break.

Stereo Binocular Viewer 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 1 1/4" drawtube to fit 2" Focuser and
1 -1/4" Visual Backs of all Schmidt-Cassegrains —
and also Focusers of refractors. Mechanical design is much
improved over American and Japanese models. The removable
1 -1/4" drawtube features a camera T-2 thread on the
Binocular side and 1 -1/4" Filter Thread on the entrance
side, to accept Celestron 1 -1/4" Eyepiece Filters.
Utilizes 1 -1/4" eyepieces (not included). Must use
two eyepieces of equal focal length and design type. Made
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
high quality 90-degree multicoated mirror diagonal allows
you to take advantage of the wider field of view provided
by 2" eyepieces. A much higher quality than standard
diagonals, it fits all rear cells of Schmidt-Cassegrains
(comes standard with CGE 1400). Includes an adapter to accept
1 1/4" eyepieces and an adapter to use with refractor
Diagonal, Mirror - 2"
A unique bracket for 50mm finderscopes, it’s designed
for 8", 9 1/4" and 11" Schmidt-Cassegrain
Telescopes. No tools are required, and once it’s aligned,
you can take it off and put it on without losing alignment.
Bracket includes necessary mounting hardware. The additional
weight of this accessory may require that you use additional
optional counterweights for your telescope.

/ Visual Accessories
Celestron’s long history of being a leader in innovation
began in the early 1960’s when it was the first to
mass produce the Schmidt Cassegrain Telescope (SCT), known
to all as the C8. Today, the term "C8" is synonymous
with the SCT. Celestron was also the first to introduce
a Schmidt Camera and a completely computer automated fork
mounted telescope to the amateur astronomer. In keeping
with this tradition of innovation, Celestron has designed
multi-focus Fastar compatible SCT telescopes. In addition
to using your telescope in the traditional photo/visual
configurations, these telescopes are optimized for f/2 (f/1.95
with the C8 and f/2.1 with the 14") prime focus CCD
The Fastar lens assembly comes with
the optical lens assembly, and protective holder for the
secondary mirror while removed from the telescope. A rear
cell counterweight to ensure proper balance when imaging
at f/1.95 is also included with the 8" systems.
With the Fastar's f/2 focus, your telescope can provide
a field of view larger than CCD systems twice its chip size
and costing thousands of dollars more. Objects like M33
and the Veil Nebula, which were previously too large for
the narrow fields of view of most commercial CCD's, will
easily be seen with the Fastar system. The Fastar compatible
C8 used at f/1.95 delivers a field of view 5 times wider
than imaging at f/10 and requires exposure times that are
25 times shorter. No more spending valuable observing time
trying to locate and frame deep-sky objects in a small field
of view. Unguided track and accumulated images of 30 seconds
or more capture deep sky objects in their full glory. It's
like having a professional observatory in your own backyard!
