All ofthe planetary filters included in the Celestron Lunar and Planetary Filter Set can be used with any 1.25\" eyepiece that has a standard filter thread, making them very versatile - Simply screw a filter on to your chosen eyepiece and insert it into the focuser.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis Celestron filter set contains the following colors:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 Dark Yellow\u003c\/strong\u003e - A good universal filter for telescopes with smaller apertures (less than 4.5\"). The yellow filter improves contrast when observing the Moon. It also helps to see the cloud bands on Jupiter and Saturn, as well as clouds and the polar ice caps on Mars and the atmospheric structures on Uranus and Neptune.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e21 Orange\u003c\/strong\u003e - Improves the visibility of plains on Mars by reducing blue and green light.

A neutral density filter, it is also useful for resolving double stars. Use it whenever you want to reduce brightness without affecting an object's color properties.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eEach Celestron 1.25\" filter has a 26mm clear aperture and is mounted in a black anodized aluminum barrel with threads on both ends.
