In 1975, Orion Telescopes & Binoculars was founded in a garage in Santa Cruz, California by Tim Gieseler, who served as its only president and CEO.[4]

Between the mid-1990s and 2005, Orion only sold binoculars, telescopes, and accessories under the "Orion" brand.[citation needed]

In January 2005, Orion was acquired by Imaginova, the U.S. conglomerate founded in 1999 by CNN business anchor Lou Dobbs.[5] Orion then began to sell non-Orion brand products, such as Tele Vue eyepieces and even Celestron 8-inch (200 mm) and 11-inch (280 mm) Schmidt-Cassegrain telescopes.[citation needed]

In November 2017, Orion was repurchased by its employees, and has remained independent and American-owned ever since.[citation needed]

Orion sells a range of telescopes that they characterize as "beginner", "intermediate" or "advanced", including Newtonians, Maksutovs, Schmidt-Cassegrains, Ritchey-Chrétiens and refractors with or without (sold as optical tube assemblies or "OTA") a variety of mounts. Orion also sells a series of Dobsonian telescopes that come in "Classic" and "IntelliScope" versions, the latter with upgraded accessories and the ability to indicate astronomical objects to the observer aided by a computerized object database. Orion also sells Dobsonians with GoTo and tracking capabilities.

In late 2005 Celestron (which had recently been purchased by Synta Technology Corporation of Taiwan) announced an agreement that would allow Celestron 8, 9.25, and 11-inch (280 mm) Schmidt-Cassegrain optical tube assemblies (OTA), painted in metallic gray and using the "Orion" brand (Celestron OTAs are painted either gloss black or semi-gloss matte orange), to be sold with Orion branded German equatorial mounts (also made by Synta)[6] and eyepiece accessories.

At the high performance end of their range, Orion has a series of two element apochromatic (apo) refractors manufactured by Synta[7] featuring "extra low dispersion" fluorite crown glass in one element of the objective lens. These are marketed as the ED80 (80 mm or 3-inch (76 mm) objective at f/7.5), ED100 (100mm or 4-inch (100 mm) at f/9) and ED120 (120mm or 4.7-inch (120 mm) at f/7.5).

Orion also sells binoculars for astronomical and terrestrial observing, microscopes and monocular spotting scopes of the type used by birdwatchers and marksmen.
