Optional Accessories

A C C E S S O R I E S

The following is a partial list of optional accessories available for your Celestron

C5 spotting scope. You will find that additional accessories enhance your

viewing pleasure and expand the usefulness of your spotting scope.

Barlow Lens - A Barlow lens is a negative lens that increases the focal length

of a telescope. Used with any eyepiece, it doubles the magnification of that

eyepiece. Celestron offers two Barlow lens in the 1-1/4" size for the C5. The

2x Ultima Barlow (#93506) is a compact triplet design that is fully multicoated

for maximum light transmission and parfocal when used with the Ultima

eyepieces. Model #93507 is a compact achromatic Barlow lens that is under

three inches long and weighs only 4 oz. It works very well with all Celestron

eyepieces.

CD-ROM (93700) - Celestron and Software Bisque have joined together to

present this comprehensive CD-ROM called The Sky™ Level 1 - from

Celestron. It features a 10,000 object database, 75 color images, horizontal

projection, custom sky chart printing, zoom capability and more! A fun, useful

and educational product. PC format.

Photo Tripod Slow Motion Controls (#93804-A) - If you have ever tried

pointing a spotting scope while mounted on a photographic tripod, you know

how tough it can be to center your subject. The Deluxe Photo Tripod Slow

Motion Control solves that problem. Fitting between the C5 and the photo-

graphic tripod, this accessory allows you to make fine pointing adjustments,

both vertically and horizontally. The Deluxe model (#93804-DX) has ultra

smooth controls and virtually no backlash.

Eyepieces - Like telescopes, eyepieces come in a variety of designs. Each

design has its own advantages and disadvantages. For the 1-1/4" barrel

diameter there are four different eyepiece designs available.

• Super Modified Achromatic (SMA) Eyepieces: 1

The SMA design is an improved version of the 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. Celestron offers SMA eyepieces in the following

focal lengths: 6mm, 10mm, 12mm, 17mm and 25mm.

• Plössl - Plössl eyepieces have a 4-element lens designed for low-to-high

power observing. The Plössls offer razor sharp views across the entire

field, even at the edges! In the 1-1/4" barrel diameter, they are available in

the following focal lengths: 6.3mm, 7.5mm, 10mm, 12.5mm, 17mm,

20mm, 26mm, 32mm and 40mm.

• Ultima - Ultima is not really a design, but a trade name for our 5-element,

wide field eyepieces. In the 1-1/4" barrel diameter, they are available in

the following focal lengths: 5mm, 7.5mm, 12.5mm, 18mm, 30mm,

35mm, and 42mm. These eyepieces are all parfocal. The 35mm Ultima

gives the widest possible field of view with a 1-1/4" diagonal and is ideal

for the C5 with or without the Reducer/Corrector.
