We provide several different classes of eyepieces to meet the needs
of our users. A detailed description of each eyepiece series is listed
below starting with our standard eyepieces and ending with our highest
quality models.

Item # 93336, E-Lux 2" 40mm
The E-Lux series of eyepieces is available in 1 1/4" 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 standard Plössls.

 If
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.

 If
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 filters.

Item # 93356, Ultima 1-1/4" 42mm
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.

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 contrast.
1-1/4" threaded barrels accept
1-1/4" Celestron filters.
*The 50mm has a 50° apparent field of view.

Eyepieces - Specialty
Item # 93230, Zoom Eyepiece 8-24mm 1-1/4"
- Focal length of 8mm to 24mm
- Field of view: 40 – 60 degrees
- Eye relief: 15 -- 18mm
- Fully Multicoated
Item # 94182, Collimation Eyepiece 1-1/4"
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 Collimation Tool.
 Item
# 94171, 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°
Item # 94169, 10mm Plössl Reticle Eyepiece 1-1/4"
 Guiding (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 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.
Item # 93326, 2x 1-1/4" Omni
 This 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.
Item # 93506, 2x 1-1/4" Ultima
 This
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
compact and lightweight, it’s just 5 ounces and 2.75" in
length.
 Item # 93327, 2x 1-1/4" X-Cel
- 2x Barlow lens with ED (extra low dispersion) glass
- Fully Multi Coated
- Ultra low profile
