Celestron Telescope Eyepiece Filter Set #3

Celestron offers four convenient filter sets, which contain four different filters per set. Not only are these highly useful filter combinations, but they also offer an economical way to add versatility to your filter collection.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, 1Œ" eyepieces, and offer a full 26mm clear aperture. #23A Light Red 25% T [Series 3] All observing information for this filter is the same as that given for the #25 filter, with the exception of the following: Mars - Reduces light from blue and green areas which darkens the maria, oases and canal markings, while lightening the orange-hued desert regions. Sharpens the boundaries of yellow dust clouds. Comets - Improves definition of comet dust tails. #38A Blue 17% T [Series 3] Moon - Enhance lunar detail. Jupiter - Enhance the boundaries between the reddish belts and adjacent bright zones. Useful for viewing the Great Red Spot. Mars - Very useful during the violet clearing. Helpful in studying surface features and polar caps. Mercury - Improve observation of dusky surface markings at twilight, when the planet is near the horizon.

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.

Celestron Oxygen III 1.25 in Telescope Narrowband Filter

The OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects. Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm. This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.

Orion V-Block 1.25in Anti-Fringing Telescope Filter

With refractors, it's normal to see some purple fringing or halos around bright objects such as the planets, Moon, and bright stars. Such false color, or chromatic aberration, results from the inability of a standard two-element ("achromatic") lens assembly to focus all wavelengths of light to a single point. The effect is particularly pronounced at higher powers. But if you are the type that thinks halos look better on angels than on astronomical objects, then our V-Block filter is for you. It effectively removes the distracting color halos from around bright objects, greatly improving image sharpness, color, contrast, and resolution.

Celestron #1A Telescope Skylight Filter

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, C9Œ, 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 C9Œ telescopes and the reducer plate of the C11 and C14 telescopes. All additional accessories mount onto the exterior/male threads.

Celestron 93608 Polarizing Filter Set

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.

Celestron Telescope Light Pollution Reducing Filter

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 vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:
