Why Schmidt telescope specially built?

This instrument was specifically designed for photographing the Sun’s corona (the outer layer), which up to that time had been successfully photographed only during solar eclipses. The coronagraph, as this special telescope is called, must be located at a high altitude to be effective.

What kind of telescope is a Schmidt-Cassegrain?

catadioptric telescope
The Schmidt–Cassegrain is a catadioptric telescope that combines a Cassegrain reflector’s optical path with a Schmidt corrector plate to make a compact astronomical instrument that uses simple spherical surfaces.

How do Schmidt-Cassegrain telescopes work?

Like a Newtonian, this design uses a parabolic mirror at one end of the tube. The light from the primary reflects to a small curved secondary mirror, then back through a hole in the primary mirror to an eyepiece. The curvature of the secondary is usually hyperbolic in modern Cassegrains.

Did Isaac Newton invent the reflecting telescope?

Isaac Newton (1642-1727, F.R.S. 1672, P.R.S. 1703-1727) is generally I credited with the invention of the reflecting telescope, having conceived the idea in 1666* (1, 2, 3).

Do modern telescopes only use light?

The Short Answer: Early telescopes focused light using pieces of curved, clear glass, called lenses. However, most telescopes today use curved mirrors to gather light from the night sky. The shape of the mirror or lens in a telescope concentrates light.

Are Schmidt Cassegrain telescopes good?

Small Maksutov-Cassegrain telescopes are a godsend for urban observers who need a compact scope with good optics. And “Maks” are back in style, so there’s a good selection on the market.

What can you see with an 8 inch Schmidt Cassegrain telescope?

4. Celestron NexStar Evolution 8 Schmidt Cassegrain Telescope. The NexStar 8 telescope also has a 200mm lens and offers spectacular views of the moon, planets, and deep sky objects.

Which is better Schmidt Cassegrain or Maksutov Cassegrain?

The main difference between Schmidt-Cassegrains and Maksutov-Cassegrains is the corrector lens at the front of the telescope. Both scopes use spherical mirrors which induce spherical aberration. Also, Maksutov-Cassegrains usually have longer focal ratios than SCTs, making them less well-suited for deep-sky photography.

Why is the reflecting telescope important?

Reflecting telescopes use mirrors to help astronomers see more clearly far-away objects in space. A mirror collects light from objects in space, forming the image. Reflecting telescopes can be much bigger and more powerful than refracting telescopes, which only use lenses to collect light.

Why is Newton’s telescope important?

Isaac Newton built his reflecting telescope as a proof for his theory that white light is composed of a spectrum of colours. He had concluded that the lens of any refracting telescope would suffer from the dispersion of light into colours (chromatic aberration).

What’s the advantage of really expensive Maksutov telescopes?

“What’s the advantage of really expensive Maksutov telescopes” Same as the advantage of really expensive refractor and reflector telescopes. Really good optics and mechanicals. In the case of Maksutovs, also better odds of getting a design that operates at full aperture and featuring beneficial cooling measures.

What is SCT telescope?

The Schmidt- Cassegrain telescope (SCT) uses a combination of mirrors and lenses (catadioptric optics) to fold the optics and form an image.

What is an astronomical telescope?

Answer Wiki. An astronomical telescope is an optical instrument which is used to see the magnified image of distant heavenly bodies like stars, planets, satellites and galaxies etc.
