Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation ...
The 2 meter telescopes are the two Faulkes telescopes built by Telescope Technologies Ltd. They are f/10 Ritchey-Chrétien optical configurations on alt-az mounts. The 1 meter telescopes are f/7.95 Ritchey-Chrétien optical systems on equatorial mounts. They have a 50 arcminute-diameter fully corrected field of view.
Stony Ridge Observatory is an astronomical observatory built by and for amateur astronomers in the mountains of Los Angeles County, California, in 1957. [1] When installed, its 760 mm (30 in) Newtonian-Cassegrain likely ranked as 8th largest of all telescopes in California, and one of the largest amateur telescopes in the United States. [2]
Shane Telescope: 3.05 m: 120" Single: USA: Lick Observatory, California, USA: 1959 NASA-LMT [5] retired: 3 m: 118" Liquid: USA: NASA Orbital Debris Obs., New Mexico, USA: 1995–2002 For telescopes below 3 meters see List of large optical telescopes
Positioning an optical telescope in space eliminates the distortions and limitations that hamper that ground-based optical telescopes (see Astronomical seeing), providing higher resolution images. Optical telescopes are used to look at planets, stars, galaxies, planetary nebulae and protoplanetary disks, amongst many other things. [150]
Two telescopes operate at TMO: The 1.02 m (40 in) Pomona College Telescope is a Cassegrain reflector built at Pomona College. It first became operational in 1985, and had new mirrors installed in 1996. [5] [6] A 0.6 m Ritchey-Chrétien reflector built by Astro Mechanics was installed in 1966. It is attached to an off-axis German equatorial ...
This is a list of the highest astronomical observatories in the world, considering only ground-based observatories and ordered by elevation above mean sea level. The main list includes only permanent observatories with facilities constructed at a fixed location, followed by a supplementary list for temporary observatories such as transportable ...
