C-90 MAKSUTOV CASSEGRAIN SPOTTING SCOPE BY CELESTRON

Celestron’s C90 is a world leader in Spotting Scopes of this size. With diffraction limited, hand-figured optics, the permanently collimated, closed tube design eliminates image degrading tube currents and keeps all internal optical elements dust-free and clean. The result is a virtually maintenance free instrument providing views ranging from butterflies at a distance of 15 feet to galaxies millions of light years away.

 

The C-90 is a completely portable, high-power-visual and high-performance-photographic instrument that opens the curtain to everything you want to see “out there.” Think forest, fields, mountains, grizzlies, hummingbirds, freighters, water lilies, frogs, and even the night sky–the C-90 is your ticket to THE SHOW!

The C-90’s extra-wide aperture and superb lens coatings maximize the throughput of light, resulting in an exceptionally bright, high-contrast image. The long focal length assures minimal distortion because with limited bending, the light rays are precisely concentrated at the focal point producing an extremely sharp image. A catadioptric optical system folds that long focal length, thus a short, conveniently compact tube is possible.
