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.

2x 1-1/4" Omni

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 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, 11ž4" 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.

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. 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 terrestrial photography.

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



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%.

Polarizing 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 entering light.

Skylight Filter



For Schmidt-Cassegrains

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.

Solar Filters

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

The 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 in Germany.

Fastar Lens Assembly




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 imaging.

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!
