Color "Planetary" Filter Sets
Dramatically Improve Planetary Views and Photos Our color filters will enhance your view of the planets and Moon, enabling you to see more detail! They selectively increase the contrast between markings of different hues and reduce "irradiation," the smudging of boundaries between light and dark regions that results primarily from turbulence in the Earth's atmosphere. Indistinct features suddenly become distinct!

Orion color filters are made from high-grade Schott optical glass and vat-dyed for even color coating, and then given an anti-reflection coating. Their anodized aluminum cells are double-threaded to permit filter stacking and are labeled with their Wratten filter number. Available in 1.25" and 2" sizes.

Different Colors Enhance Subtle Surface Details
Orion Color Planetary Filter Sets

Planetary and lunar observation is almost always improved by the use of color filters. They bring out subtle details by selectively increasing the contrast among markings of different hues, and by reducing “irradiation,” the smudging of the boundaries between light and dark regions due primarily to turbulence in the Earth’s atmosphere.

With the right color filter, suddenly the indistinct, pale bands of Jupiter resolve into loops and festoons. Delicate markings appear on Saturn’s globe, and the Cassini and crepe divisions darken and solidify. Mars’ polar caps stand out like tiny pearls, and vague lunar rilles acquire greater depth and contrast. Bad “seeing” becomes acceptable; good seeing becomes superb!

Because many planets have a characteristic color (e.g., Mars is reddish), a color filter will reduce the predominant hues to enhance contrast and uncover hidden surface markings. That’s why “the Red Planet” is most effectively enhanced with a green filter!

Orion color planetary filters are the absolute best available. Made from high-grade Hoya optical glass, each is vat-dyed for even color distribution and then fully antireflection coated. The glass is held in an anodized aluminum cell labeled with the appropriate Wratten filter number. The cell is double-threaded to permit threading of the filter into the barrel of an eyepiece as well as the stacking of filters for additional filtration options.
