It’s an obvious target that’s easy to locate and full of exciting geographical features to explore. Moon filters enhance lunar viewing by cutting down on the Moon’s bright glare, improving contrast and making faint details easier to observe. Amateur astronomers refer to Moon filters as “sunglasses for the Moon” because they provide a more comfortable view and reduce eye fatigue.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eThis Moon Filter Set contains all the filters you will ever need to observe the Moon during its various phases.

The ND96-0.9 filter transmits 13% of the incoming light, the ND96-0.6 transmits 25% and the ND96-0.3 transmits 50%. They do not impart any color to the Moon, but reduce lunar brightness. With several ND filters to choose from, you can find just the right level of light transmission for the Moon depending on its phase, the aperture of your telescope, and the magnification of your eyepiece. ND filters can also be used reduce the glare from Venus to better see its crescent phases, and to help dim bright daytime views when using a telescope terrestrially.\u003c\/li\u003e\n\u003cli style=\"box-sizing: inherit; position: relative; margin-bottom: 5px; padding-left: 15px;\"\u003e\n\u003cspan style=\"box-sizing: inherit; font-weight: bolder;\"\u003eA Moon \u0026amp; Sky Glow filter — \u003c\/span\u003eThis filter selectively reduces light transmission at different wavelengths and greatly improves contrast for observing subtle lunar features.

Our eyes are not ready for the bright beam of light that emits from the eyepiece, and they “stop down”, just as they would when you step out into the sunlight on a bright summer’s day. When we’re in the sunlight, we often wear sunglasses. They help us relax our eyes, protect us from glare, and help us see things more clearly. When amateur astronomers observe the Moon, we use a moon filter. A Celestron Moon Filter provides similar benefits to those of sunglasses...our eye relaxes and opens up to let us see more detail. This is especially important when observing the Moon when it is near full.\u003c\/p\u003e\u003cp style=\"box-sizing: inherit; margin: 0px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003eThe Celestron Moon Filter simply screws onto the insert barrel of most 1.25” eyepieces.
