Powerful laser guide star system at the Paranal Observatory. The actual laser guide star is the small spot above the apparent end of the laser beam. A laser guide star is an artificial star image created for use in astronomical adaptive optics systems, which are employed in large telescopes in order to correct atmospheric distortion of light (called astronomical seeing).
Starfire Optical Range (SOR - Pronounced as an initialism) is a United States Air Force research laboratory on the Kirtland Air Force Base in Albuquerque, New Mexico.Its primary duty, according to the official website, is to "develop and demonstrate optical wavefront control technologies."
The Automated Planet Finder (APF) Telescope a.k.a. Rocky Planet Finder, [1] is a fully robotic 2.4-meter optical telescope at Lick Observatory, situated on the summit of Mount Hamilton, east of San Jose, California, USA. [2] It is designed to search for extrasolar planets in the range of five to twenty times the mass of the Earth. The ...
This is a list of United States Army fire control, and sighting material by supply catalog designation, or Standard Nomenclature List (SNL) group "F".The United States Army Ordnance Corps Supply Catalog used an alpha-numeric nomenclature system from about the mid-1920s to about 1958.
Tour guide points out the double Finderscope on the 24.5 inch Cassegrain Telescope at the Goldendale Observatory State Park. A finderscope is an accessory sighting device used in astronomy and stargazing, typically a small auxiliary refracting telescope/monocular mounted parallelly on a larger astronomical telescope along the same line of sight.
Lick Observatory's Shane 120-inch (3-meter) telescope (center) along with the nearby Automated Planet Finder 100-inch (250-centimeter) reflector. Below is a list of the nine telescopes currently operating at the observatory: [42] The C. Donald Shane telescope 120-inch (3-meter) reflector (Shane Dome, Tycho Brahe Peak). Its instrumentation includes:

Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
