Focuser Assembly – #93670 Celestron offers this very smooth and economical 1 1 / 4 " rack and pinion focuser for Newtonian telescopes. The focuser glides easily and provides 2" of focus travel. An adapter is included to allow use with .96" eyepieces as well as 1 1 / 4 " eyepieces.
6 Economy Eyepieces: .96" and 1 1 / 4 " Celestron offers these very economical eyepieces to expand your viewing options. They are all simple eyepiece designs — Ramsden (SR & F) and Huygens (H & HM) but perform quite well on f/8 or slower telescopes.
7 Plössl Eyepieces: .96" and 1 1 / 4 " In a recent Sky and T elescope review , Celestron’ s .96" and 1 1 / 4 " Plössl eyepieces were rated as top ranking, and found to outperform many similar , but more expensive eyepieces.
8 L V Eyepieces: 1 1 / 4 " These Vixen brand eyepieces (6 to 8 elements) are a new breed, using the rare earth glass lanthanum in one of their field lenses, for almost total freedom from any visual aberrations. All focal lengths have a comfortable 20mm of eye relief.
Ultima Spotting Scope Eyepieces Extremely high quality eyepieces designed exclusively for the Ultima line of spotting scopes. Model 65mm Spotter 80mm Spotter Mount T ype #1828 20x 25x Bayonet #1830 40.
10 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.
11 Diagonals: .96" and 1 1 / 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.
12 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.
13 Quick Release Finder Bracket – #51149-A A unique bracket for 50mm finderscopes, it’ s designed for C8, C9 1 / 4 and C11 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 mount- ing hardware.
14 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 excel- lent homogeneity .
15 #8 Y ellow 83% T [Series 4] All observing information for this filter is the same as that given for the #12 and #15 Deep Y ellow filters, with the exception of the following: Mars – Improves the Martian maria by reducing scattered light from blue areas, while allowing passage of more green light for studying yellow dust clouds.
16 GREEN #56 Light Green 53% T [Series 2] Moon– Enhances lunar features. Jupiter – Increases visibility of the Great Red Spot. Useful for observing the low-contrast hues of blue and red that exist in the Jovian atmosphere. Mars – Excellent for increased contrast of Martian polar caps, low clouds and yellowish dust storms.
17 1 1 / 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.
18 Solar Filters Celestron’ s Solar Skreen ® solar filters transmit .001% of visible light, allowing direct observation of the sun. Y ou 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.
19 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.
20 T o allow automatic tracking of celestial objects, Celestron offers several motor drives. All models include a hand controller , which makes obser v- ing more fun as it makes centering objects much easier . In addition, the hand controller can be used as a drive corrector for long expo- sure celestial photography .
21 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 ill uminator — choose from models #60001 and #60011. 12mm Kellner Reticle Eyepiece: 1 1 / 4 " – #94170 The reticle pattern is a .
22 Reducer/Corrector f/6.3 – #94175 This combination focal reducer and field corrector lens accessory works with all Celestron C5, C8, C9 1 / 4 , C11 and C14 telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality .
23 Hand Controller – #28983 For use with the C5 + and Celestar 8, both for astrophotography and CCD imaging. It’ s also great for obser ving, 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).
24 Counterweights Using accessories such as cameras, Lens Shades, T ele-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 .
25 T -Adapters 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 photogra- phy and short exposure lunar and planetary photography . It can also be used for long exposure deep-sky photography when using a separate guidescope.
26 Deluxe T ele-Extender – #93643 The Deluxe T ele-Extender for Schmidt-Cassegrain telescopes is a hollow tube that allows you to attach a camera to your telescope, with an eyepiece installed.
27 Digital Setting Cir cles: Advanced Astro Master ® Computerize your telescope! This pointing system contains a database of over 10,000 objects. Once aligned, it will guide you to any one of these objects.
28 Planisphere 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.
29 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.
30 T RIPODS Photographic/V ideo T ripod – #93596 For use with photographic and visual instruments fitted with a standard 1 / 4 " x 20 threaded hole. The Photo T ripod provides stable support for video cameras, telephoto lenses, spotting scopes and binoculars.
31 Lightweight Field T ripod – #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.
32 E QUA TORIAL W EDGES 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 W edge. The wedge allows you to tilt the telescope so that its polar axis (R.
33 T elescope Equatorial Mount – CG-3 – #91503 A durable, rigid, German equatorial mount with a wooden tripod, offering both affordability and high quality . Designed as an excellent and inex- pensive upgrade option when you’re ready to move to a sturdier mount for your beginning telescope.
