  • Päikese krooni detailseks pildistamiseks ja filmimiseks kasutatav teleskoop, millel on päikeseketta üliheleda valguse vastu ümarkatik
  • device fitted to a telescope that blocks out the bright disc of the Sun or a star, allowing the solar or stellar corona to be viewed
koronograaf
Usage examples
  • Koronograaf koosneb valgust varjutavast kettast ning hajunud valgust ja difraktsiooni kõrvaldavatest lisadiafragmadest.
coronagraph
Usage examples
  • Roman will use its Coronagraph Instrument – a system of masks, prisms, detectors, and even self-flexing mirrors built to block out the glare from distant stars and reveal the planets in orbit around them – to demonstrate that direct imaging technologies can perform even better in space than they have with ground-based telescopes.

  • teleskoobile paigaldatud seade, mis blokeerib tähe ereda ketta, võimaldades tähe krooni vaadata, pildistada ja filmida
  • teleskoobile kinnitatud seade, mis on mõeldud tähe otsese valguse blokeerimiseks, nii et läheduses asuvaid objekte, mis muidu oleksid peidetud tähe eredasse pimestamisse, saab vaadata ja pildistada
  • device fitted to a telescope that blocks out the bright disc of a star, allowing the star's corona to be viewed
  • telescopic attachment designed to block out the direct light from a star so that nearby objects – which otherwise would be hidden in the star's bright glare – can be resolved
koronograaf preferred
Usage examples
  • Enamik koronograafe on mõeldud Päikese krooni vaatlemiseks, kuid kasutatakse uut kontseptuaalselt sarnast mõõtevahendite klassi (mida nimetatakse tähe koronagraafideks, et eristada neid päikese koronagraafidest) maaväliste planeetide ja ümbermõõtketaste leidmiseks lähedalasuvate tähtede ümber, samuti peremeesgalaktikate kvasarites ja muudes sarnastes objektides, millel on aktiivsed galaktilised tuumad.

coronagraph preferred
Usage examples
  • Most coronagraphs are intended to view the corona of the Sun, but a new class of conceptually similar instruments (called stellar coronagraphs to distinguish them from solar coronagraphs) are being used to find extrasolar planets and circumstellar disks around nearby stars as well as host galaxies in quasars and other similar objects with active galactic nuclei.
