The Orion 1.25" Premium 20-Piece Color Planetary Filter Set is an ideal accessory for any backyard stargazer who enjoys observing the planets of our solar system. This Premium 20-piece filter set includes our most complete assortment of 1.25" color filters to help enhance observations of the Moon and planets.
Since planetary surface details and atmospheric phenomena reflect sunlight as contrasting colors, you can use color filters to accentuate subtle details on planets, comets, and the Moon by selectively increasing contrast between features and markings of different hues. Simply put: using various color filters makes planetary details easier to see. You can also "stack" multiple filters to combine filtration effects for unique results.
Each filter included in the Orion Premium 20-Piece Color Planetary Filter Set is vat-dyed for even color coating and then anti-reflection coated for peak performance. Each included color filter features a 1.25" anodized aluminum cell threaded for use with 1.25" Orion telescope eyepieces. Filters can also be stacked to achieve additional enhancement benefits. Each filter can also be used with filter wheels and/or filter sliders for quick and convenient swapping during viewing sessions to compare differently filtered views. (Filter wheels and filter sliders sold separately.)
Below is a list of each filter included in the Orion Premium 20-Piece Color Planetary Filter Set, along with just a couple of the planetary and lunar features they help accentuate. A more detailed summary of suggested uses for each filter is featured in the instruction manual that comes with the filter set. The manual also includes detailed transmission graphs for each of the 20 color filters.
