For hundreds of years, telescopes have helped astronomers unravel the mysteries of the Universe. But what’s involved in making – and maintaining – the complex instruments of today? The origins of the telescopeorigins of the telescope royal netherlands academy of arts and sciences, 2010i History The Ooty Radio Telescope is located in Muthorai near Ootacamund (Ooty), south India. It is part of the National Centre for Radio Astrophysics (NCRA) of the well known Tata Institute of Fundamental Research (TIFR) which is funded by the… 1672 — Laurent Cassegrain, produces a design for a reflecting telescope using a paraboloid primary mirror and a hyperboloid secondary mirror. The Large Synoptic Survey Telescope (LSST), also known as the Vera C. Rubin Observatory, is a wide-field survey reflecting telescope with an 8.4-meter primary mirror, currently under construction, that will photograph the entire available… The telescope saw first light in 1998 and is named after the Italian Renaissance astronomer Galileo Galilei. The Overwhelmingly Large Telescope (OWL) was a conceptual design by the European Southern Observatory (ESO) organization for an extremely large telescope, which was intended to have a single aperture of 100 meters in diameter.
This has significant advantages for spectrographs and other heavy instruments typically used at research observatories. Most modern research telescopes can be configured into a Nasmyth telescope (i.e. to use the "Nasmyth Focus").
A Standard Folded design would put the 6 inch f/15 into a tube 12 inches in diameter and 29 inches long – short and squat. The Offset Folded Refractor is contained in a tube 10 inches in diameter and 36 inches long; still pretty short and squat but slightly thinner and a bit more compact. The following diagram illustrate the differences. Above: Optical layout of a typical Cassegrain reflecting telescope This section details the optical design and inherent aberrations of Cassegrain-type reflecting telescopes. For a more basic overview of these designs please see the Ritchey-Chrétien page and the Cassegrain page. For a review of the optical design terms, see the Optical Aberrationsand Optical Design sections. Star Testing Your Telescope the magnitude of the defect. Severe errors on any telescope include astigmatism that origi-nates on the glass, bad zones or severe roughness. These warrant returning the telescope. If the errors are minor, weigh the likelihood that you will get better optics at the same price.

The Large Synoptic Survey Telescope (LSST), also known as the Vera C. Rubin Observatory, is a wide-field survey reflecting telescope with an 8.4-meter primary mirror, currently under construction, that will photograph the entire available sky every few nights.
In 1952, Hans Wolter outlined three ways a telescope could be built using only this kind of mirror. These are called Wolter telescopes of type I, II, and III.
