Equatorial telescope mounts come in many designs. In the last twenty years [when?] motorized tracking has increasingly been supplemented with computerized object location. There are two main types. Digital setting circles take a small computer with an object database that is attached to encoders. The computer monitors the telescope's position ...
SDSS uses a dedicated 2.5 m wide-angle optical telescope; from 1998 to 2009 it observed in both imaging and spectroscopic modes. The imaging camera was retired in late 2009, since then the telescope has observed entirely in spectroscopic mode. Images were taken using a photometric system of five filters (named u, g, r, i and z).
The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric thread on the lens with a flange focal distance of 55 mm and a mating female 42mm thread on a camera adapter or other optical component.
On a mountaintop in northern Chile, the Vera C. Rubin Observatory, which holds the largest digital camera in the world, is preparing to power up. Telescope with world’s largest digital camera ...
The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS1; obs. code: F51 and Pan-STARRS2 obs. code: F52) located at Haleakala Observatory, Hawaii, US, consists of astronomical cameras, telescopes and a computing facility that is surveying the sky for moving or variable objects on a continual basis, and also producing accurate astrometry and photometry of already-detected objects.
In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts. [5] The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms. [6]
The Advanced Camera for Surveys in the clean room at the Goddard Space Flight Center in Maryland, prior to its installation on the Hubble Space Telescope Astronauts remove the FOC to make room for the ACS in 2002 The STS-125, shown here on the launchpad, went on to repair the Advanced Camera for Surveys and returned the crew safely back to Earth
Spectrography setup with autoguider (the autoguider camera body is attached to the finderscope, top right, and the guiding computer, bottom right).. An autoguider is an automatic electronic guidance tool used in astronomy to keep a telescope pointed precisely at an object being observed.
