    The Catalina Sky Survey (CSS) uses three telescopes, a 1.5-meter (59 in) f/1.6 telescope on the peak of Mount Lemmon (MPC code G96), a 68 cm (27 in) f/1.7 Schmidt telescope near Mount Bigelow (MPC code 703), and a 1-meter (39 in) f/2.6 follow-up telescope also on Mount Lemmon (MPC code I52).

  4. Spherical astronomy - Wikipedia

    en.wikipedia.org/wiki/Spherical_astronomy

    It relies on the mathematical methods of spherical trigonometry and the measurements of astrometry. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects have been, and continue to be, important for religious and astrological purposes, as well as for timekeeping and navigation. The science of ...

    en.wikipedia.org/wiki/Celestial_cartography

    Astrometry, the science of spherical astronomy, is concerned with precise measurements of the location of celestial bodies in the celestial sphere and their kinematics relative to a reference frame on the celestial sphere. [8] In principle, astrometry can involve such measurements of planets, stars, black holes and galaxies to any celestial ...

    Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy , the Milky Way .

  7. Sloan Digital Sky Survey - Wikipedia

    en.wikipedia.org/wiki/Sloan_Digital_Sky_Survey

    This method allows consistent astrometry over the widest possible field and minimises overheads from reading out the detectors. The disadvantage is minor distortion effects. The telescope's imaging camera is made up of 30 CCD chips, each with a resolution of 2048 × 2048 pixels , totaling approximately 120 megapixels . [ 11 ]

    Astrometry. Professional setups are using astrometric solving to measure accurately the position of minor planets or comets to calculate orbital parameters. [5] Telescope Mount pointing. Astrometric solving is used for pointing the telescope mount accurately by syncing it to the celestial position of the image center. [6]
