Cassegrain Telescope

Schmidt-Cassegrain telescope A Schmidt-Cassegrain Telescope, invented by Bernhard Schmidt, is a catadioptric telescope.

Cassegrain telescope A type of reflecting telescope whose eyepiece is located behind the primary mirror. The primary mirror is cast with a hole in the center.

CASSEGRAIN TELESCOPE A Cassegrain telescope is a wide-angle reflecting telescope with a concave mirror that receives light and focuses an image.

Cassegrain telescope A type of reflecting telescope in which incoming light hits the primary mirror and is then reflected upward toward the prime focus where a secondary mirror reflects the light back down through a small hole in the main mirror into ...

SCHMIDT-CASSEGRAIN TELESCOPE A Schmidt-Cassegrain telescope (SCT) is a wide-angle reflecting telescope with a correcting lens that minimizes spherical aberration and a concave mirror that receives light and focuses an image.

1: Galileo used a Cassegrain telescope. 2: Galileo used the first radio telescope. 3: Galileo used the first reflector telescope. 4: Galileo used a refractor.

Maksutov's are in fact Cassegrain telescopes: In the case of a Maksutov the light enters the front of the telescope via a curved corrector plate or lens (curved towards the interior of the telescope) which directs the light onto the concave primary ...

I managed to save enough money and purchased a 10-inch Meade schmidt cassegrain telescope with a motorized base. I was totally blown away by the improvement in picture quality with the new instrument.

Here's an example: say you have a 25mm Plossl eyepiece that has a 50 degree apparent field of view and your telescope is an 8-inch f/10 Schmidt-Cassegrain telescope, with a focal length of 2000 mm.

Although this design looks like a typical Cassegrain telescope, the mirror surfaces are of a different shape, and the focusing system uses an additional corrective element. The telescope's housing is also unique.

The third type that I mentioned was the Schmidt Cassegrain telescope. It has grown in popularity because it combines the best of a reflector and refractor.

In the classical Cassegrain telescope, the primary mirror is paraboloid shaped. This brings the light of any object in the field of the telescope to a focus near the top end of the tube, called the prime focus.

Many of these are larger than the field of view of the 8" f/10 Schmidt Cassegrain telescope I currently use. A short focal ratio Newtonian like a 10" f/4.

The optics for Galileo's SSI, inherited from Voyager, consist of a Cassegrain telescope with a 176.5-mm aperture and a fixed focal ratio of f/8.5.

66 m focal length Cassegrain telescope with a 1200Ã-1200px CCD detector. The timing of the launch was planned to coincide with the rising phase of the solar maximum.

This is a CCD image of comet 1993a Mueller, taken on October 6, 1993 with a 288mm f/5.2 Schmidt-Cassegrain telescope. The comet has a coma diameter of 3' and a fan-shaped tail, up to 7' long. (Courtesy Erich Meyer and Herbert Raab, Austria) ...

The Cassegrain telescope is similar but produces an inverted image. (b) An early type of reflecting telescope similar to the Cassegrainian arrangement, except that both mirrors were converging. See also reflector.

Ramsden (Phil. Trans. vol. xix. p. 419) suggested the division of the small speculum of a Cassegrain telescope and the production of double image by micrometric rotation of the semispecula in the plane passing through their axis. Brewster (Ency.
