but perform quite well on f/8 or slower
telescopes. The optics are all glass and

powers easily available.

most eyepieces display an image). Especially useful for
daytime terrestrial observing.

Super Modified Achromatic (SMA)

Eyepieces: .96" and 11/4"

Kellner eyepiece. SMAs are very good, economi­cal, general purpose eyepieces that deliver a wide
apparent field, good color correction and an
excellent image at the center of the field of view.

contrast. Celestron offers a range of SMA
eyepieces in both .96" and 1

Ultima®Eyepieces: 11/4"

These are Celestron’s top of the line eyepieces, utilizing
a hybrid design of five elements. 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 thread-in filters. Lens
and barrel caps are included for safe storage.

BARLOW LENSES

Barlow lenses offer an easy, economical way to
increase the magnification range of your eyepieces,
and Celestron carries an assortment 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.
The Economy models of .96" and 1

1

/4" are good choices when you want to

expand your power ranges at a very economical price.
Celestron’s premium quality .96" and 11/4" achromatic Barlow lenses (#93502

and #93507) are compact and lightweight. Both are under three inches long,
with the 1

DIAGONALS

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"

1

to 1

/4" 45° Erect Image Diagonal on a telescope
equipped with .96" eyepieces means greater versatil­ity. This diagonal will allow you to use 1
pieces, to obtain a larger field of view and better eye
relief. A 90° 1

1

/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.

The economy Hybrid Mirror Diagonal (90°) provides
a cost effective way to upgrade telescopes supplied
with .96" eyepieces, to higher quality 1
