Green Witch Filters (DH)

Moon Filter 1.25" Ref: GW-MoonFilter

GREEN WITCH

The Moon can be dazzling when seen through a telescope, especially when full or near full. A moon filter makes it more comfortable to view and to see fine detail. It also helps to preserve your night vision. We consider it to be an essential accessory.

Polarizing Filterset Ref: DH-93608

CELESTRON

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 colour of the object being observed.

The Filter Set is made up 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 the light.

SkyLight Filter 31.7 Ref: DH-93621

CELESTRONFor 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.
