This is a Celestron Lunar and Planetary Filter Set - 1.25" size. Colored filters are used in astronomy to bring out details on a planet’s surface or its cloud structure. All of the planetary filters included in the Celestron Lunar and Planetary Filter Set can be used on any 1.25” eyepiece as long as it has the proper filter threads, so they are very versatile. Just screw one onto the eyepiece you are going to use and install it into your telescope's focuser.

Each one of these Celestron 1.25” filters has 26 mm of clear aperture, and is mounted in a black anodized aluminum cell that is threaded on both sides. The provision of these double threads allows the user to stack different filters together to create a custom color or affect the transmission percentage. Special coatings on each filter protect against reflections, ghosting, and scratches. A plastic case has been included to store your filters safely when they are not in use.

This Celestron Lunar and Planetary Filter Set - 1.25" includes the following filters:

• #12 Deep Yellow - A good general purpose filter for smaller aperture telescopes (less than 4.5”), the #12 Yellow will improve the contrast of features on the Moon. It will also help you see the equatorial belts on Jupiter and Saturn, clouds and the polar ice caps on Mars, and the dusky detail on Uranus and Neptune.
• #21 Orange - Sharpens the boundaries along the plains of Mars due to the reduction of blue/green transmissions. Use on Jupiter and Saturn to enhance detail in the belts and polar regions.
• #80A Blue - Enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don’t mind the change in the visual color.
• ND-96-0.3 Neutral Density - A great filter for the Moon, and for stacking with other planetary filters to increase density without changing the color. A neutral density filter is also useful when splitting binary star systems (double stars). Use anytime you want to decrease brightness but don’t want to affect the colors of the objects you are viewing.
