Orion ED120 apo refractor on Orion's Sirius EQ-G "GoTo" and GPS equipped German equatorial mount with portable 12 volt power supply. Orion sold 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 ...
The Astroscan had a Newtonian reflector layout with a 4 + 1 ⁄ 8 in (10 cm) clear-inch diameter f/4.2 aluminized and overcoated borosilicate glass parabolic primary mirror with a focal length of 17 + 1 ⁄ 2 inches (44 cm). [1] The telescope's secondary mirror was mounted on a flat optical window at
In 2013, NASA reactivated the WISE telescope to search for near-Earth objects (NEO), such as comets and asteroids, that could collide with Earth. [12] [13] The reactivation mission was called Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). [13] As of August 2023, NEOWISE was 40% through the 20th coverage of the full sky ...
Meta's AR glasses, called Orion, are impressive. But they aren't yet for sale. ... I'd buy them in a heartbeat — if they were actually for sale. Peter Kafka. Updated September 25, 2024 at 3:14 PM.

The telescope used by Berkowski was attached to 6 + 1 ⁄ 2-inch (17 cm) Königsberg heliometer and had an aperture of only 2.4 in (6.1 cm), and a focal length of 32 in (81 cm). Commencing immediately after the beginning of totality, Berkowski exposed a daguerreotype plate for 84 seconds in the focus of the telescope, and on developing an image ...
The C-Band All Sky Survey (C-BASS) was a 6.1 m (20 ft) telescope used to survey the sky in the C band in support of Cosmic microwave background research. [11] A unique feature of the telescope was the use of radio-transparent foam to support the secondary mirror. The telescope began operating in 2009 [12] and was decommissioned in 2015.
The Optical Monitor (OM) is a 30 cm (12 in) Ritchey–Chrétien optical/ultraviolet telescope designed to provide simultaneous observations alongside the spacecraft's X-ray instruments. The OM is sensitive between 170 and 650 nanometres in a 17 × 17 arcminute square field of view co-aligned with the centre of the X-ray telescope's field of view.
