Planetary (Color) Filters
Backyard observers also utilize an array of color eyepiece filters to glean subtle features on the planets. Earth's atmosphere is in constant fluctuation; turbulent air currents blur fine surface detail on solar system objects, like planets, viewed through a telescope. Faint, contrasting areas blend together due to irradiation - distortion of the boundaries between light and dark areas. Using color eyepiece filters can help reduce such distortion.

A color filter zeros in on a narrow region of the spectrum, reducing the scattering of interfering wavelengths. Because many planets have a characteristic color (e.g., Mars is reddish), a filter can dramatically increase detail by reducing the predominant hues and uncovering hidden contrast and surface markings. That's why the Red Planet is most effectively enhanced with a green filter. Each color eyepiece filter passes its characteristic color of light while blocking complementary colors. For example, green objects will appear bright (pale) through a green filter, and dark through a blue or red filter. Red features will appear bright through a red eyepiece filter and dark through a green or blue eyepiece filter.

Telescope eyepiece filters thread into the barrel of an eyepiece. Usually the aluminum cell holding the filter is threaded such that two or more can be "stacked," to achieve simultaneous filtering of more than one color.

Color filters go by their "Written" numbers. Here is a rundown of the color eyepiece filters that are useful for enhancing detail on each planet and some other objects.

 

Moon Filters
Believe it or not, you're also dealing with bright, albeit reflected, sunlight when you turn your scope on the Moon. A noncrescent Moon will consistently leave spots even in a hardened lunar observer's eyes, although this will not damage your eyes.

To tone down the glare, a Moon filter can be used. This inexpensive accessory threads into a telescope eyepiece and blocks a large percentage (typically over 80%) of the light, making for more comfortable viewing and bringing out more lunar surface details.
