Refracting Telescope: A refracting telescope uses two lenses to form an image. One as an eyepiece and another as the objective. The magnification of a refracting telescope is M=−f1f2 Where, Mis the magnification f1 f2 Answer and Explan...
What is an astronomical telescope?Telescope Uses:Telescopes are used to make distant objects look bigger. On the Earth this can be useful for anyone observing birds, airplanes, football games, or even for water rescue. The design of a telescope is usually dictated by its purpose....
An extremely large telescope is a powerful astronomical instrument with a large aperture, high spatial resolution, and astrometric precision, enabling detailed observations of celestial objects and phenomena such as microlensing events.

One form of astronomical telescope, which has a large primary concave mirror to collect the light and reflect it back to a smaller secondary convex mirror, is the Ritchey–Chrétien design of 1924. Both mirrors are hyperbolic in shape, completely eliminating spherical aberration. This is the ...
They record ultraviolet light from the sun at two to six different wavelengths from 305 to 345 nm. The measuring principle uses the fact that ozone absorption depends on the wavelength: whereas light is strongly absorbed at 305 nm, this is not anymore the case at 325 nm. The ratio between...
Today, the project uses an improved version of that early device; now the detectors are named AMDn (Astroparticle Muon Detector, followed by a model number) and are Geiger–Müller Tube (GMT)-based. Each instrument uses at least two stacked sensors (GMT) in a well-known configuration, the...
