A telescope or an attachment for a telescope equipped with a disk that blacks out most of the Sun, used to photograph the Sun's corona.
A telescope that blocks out the Sun with a black disk so that its corona is visible
An instrument that makes it possible to observe the corona at times other than during an eclipse. A simple lens focuses the Sun onto a disk that blocks the light from the solar disk, providing an artificial eclipse. This image of the Sun is from the SOHO/LASCO coronagraph instrument.
a special type of telescope that uses a disk to block out the bright light of the Sun. Coronagraphs can see the faint outer atmosphere of the Sun, as well as stars and planets that happen to be close to the Sun in the sky.
A type of telescope with which the corona can be seen at times other than that of a total solar eclipse. A to F | G to L | M to R | S to Z
An instrument for photographing the corona and prominences of the sun at times other than at solar eclipse.
special telescope carefully designed to photograph the chromosphere and inner corona of the Sun without the intervention of an eclipse of the Sun.
a device that blocks out the Sun's blinding glare with an occulting disk so that the faint corona is visible, as well as surrounding stars and planets
a device that blocks the glare of the Sun so that the faint corona, as well as surrounding stars and planets, are visible
a device that blocks the Sun's glare behind an opaque disk
a device used to block light from a star so nearby objects may be seen
an instrument that can look at the faint outer layers (the corona ) of the Sun by covering the bright solar disk
a telescope that can see things very close to the Sun
a telescope that is designed to block light coming from the solar disk, in order to see the extremely faint emission from the region around the sun, called the corona
Telescope for observing the corona. Often contains an occulting disk which covers the disk of the Sun so that the corona may be more easily observed. more
A special telescope which blocks light from the Sun's disc, thus creating an artificial eclipse, in order to study its atmosphere.
A special telescope which blocks light from the disk of the Sun in order to study the faint solar atmosphere.
An instrument which studies the Sun's outer atmosphere, the " corona". From Earth this is most easily seen during a total eclipse. SOHO has two coronagraphs which study the Sun from space. A very common way to observe the corona is to cover the bright disk of the Sun. This creates a sort of false eclipse and allows us to see the Sun's fainter outer atmosphere. A coronagraph (here the SOHO/UVCS instrument) helps show the Sun's outer atmosphere (outside of inner black circle). The coronagraph does not image the Sun's disk, but another Sun image (from SOHO/EIT) is superimposed on the area where the Sun's disk would be.
A coronagraph is a telescopic attachment designed specifically to block out the harsh, direct light from a star, so that nearby objects can be resolved without burning out the telescope's optics. 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 around nearby stars.
