  2. Astroscan - Wikipedia

    en.wikipedia.org/wiki/Astroscan

    The Astroscan had a Newtonian reflector layout with a 4 + 18 in (10 cm) clear-inch diameter f/4.2 aluminized and overcoated borosilicate glass parabolic primary mirror with a focal length of 17 + 12 inches (44 cm). [1] The telescope's secondary mirror was mounted on a flat optical window at

  3. Pan-STARRS - Wikipedia

    en.wikipedia.org/wiki/Pan-STARRS

    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.

  4. Bahtinov mask - Wikipedia

    en.wikipedia.org/wiki/Bahtinov_mask

    The telescope is pointed at a bright star, and a mask is placed in front of the telescope's objective (or in front of the aperture). The mask consists of three separate grids, positioned in such a way that the grids produce three angled diffraction spikes at the focal plane of the instrument for each bright image element.

  5. Altazimuth mount - Wikipedia

    en.wikipedia.org/wiki/Altazimuth_mount

    In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts.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]

  6. Wide-field Infrared Survey Explorer - Wikipedia

    en.wikipedia.org/wiki/Wide-field_Infrared_Survey...

    With its coolant depleted, the spacecraft's temperature was reduced from 200 K (−73 °C; −100 °F) — a relatively high temperature resulting from its hibernation — to an operating temperature of 75 K (−198.2 °C; −324.7 °F) by having the telescope stare into deep space.

  7. Fine guidance sensor - Wikipedia

    en.wikipedia.org/wiki/Fine_Guidance_Sensor

    A fine guidance sensor (FGS) is an instrument on board a space telescope that provides high-precision pointing information as input to the telescope's attitude control systems. Interferometric FGSs have been deployed on the Hubble Space Telescope; a different technical approach is used for the James Webb Space Telescope's FGSs.

  8. Super-pressure Balloon-borne Imaging Telescope - Wikipedia

    en.wikipedia.org/wiki/Super-pressure_Balloon...

    The Super-pressure Balloon-borne Imaging Telescope (SuperBIT) is a highly stabilized, high-resolution telescope that operates in the stratosphere via NASA's superpressure balloon (SPB) system. At approximately 35 km altitude above sea level, the football-stadium -sized balloon carries SuperBIT (at 3500 lbs) to a suborbital environment above 99. ...

  9. Lucky imaging - Wikipedia

    en.wikipedia.org/wiki/Lucky_imaging

    Used at a 1% selection or less, lucky imaging can reach the diffraction limit of even 2.5 m aperture telescopes, a resolution improvement factor of at least five over standard imaging systems. Zeta Bootis imaged with the Nordic Optical Telescope on 13 May 2000 using the lucky imaging method.
