electron telescope
1. A mechanism used to see through haze and fog when an infrared image is formed optically on the photoemissive mosaic of an electron-image tube and then made visible by the tube.
2. An instrument in which the infrared light of a distant object is focused onto a photocathode tube, enlarged by a series of electron lenses, and reproduced onto a fluorescent screen to form an image of the object.
3. A telescope in which an infrared image of a distant object is focused on the photosensitive cathode of an image converter tube.

Hubble Space Telescope
A space-based astronomical observing facility, orgiting the earth at an altitude of 610 kilometers/380 miles.
It is constructed of a 2.4 meter/94 inch telescope and four complimentary scientific instruments, which are roughly cylindrical, 13 meters/43 feet long, and four meters/13 feet in diameter, with two large solar panels.
radio telescope
An instrument used to make observations of celestial bodies at radio wavelengths.
The equipment usually consists of an aerial which collects the radiation and feeds it to a processing computer.

refractor telescope
A telescope that uses lenses to gather light from faint objects.
The front, objective, lens is usually made of two or more components, with the eyepiece at the other end being the point at which the observer sees the image of the object.

Schmidt camera, Schmidt telescope
1. A telescope-camera able to take pictures covering a wide area of the sky without optical problems by virtue of having a specially shaped corrector plate near its upper-end.
2. A wide-angle photographic telescope used in astronomy which has a special internal mirror to correct optical aberrations.
3. A type of reflecting telescope; more accurately, a large camera, in which the coma produced by a spherical concave mirror is compensated for by a thin correcting lens placed at the opening of the telescope tube and has a usable field of 0°.6.

3. A type of reflecting telescope; more accurately, a large camera, in which the coma produced by a spherical concave mirror is compensated for by a thin correcting lens placed at the opening of the telescope tube and has a usable field of 0°.6.
The Schmidt telescope has a corrector lens that prevents distortions of the image which is produced by its large spherical mirror.
Something called spherical aberration occurs when the uncorrected mirror does not focus all of the light rays at the same point.
