Best answer: How does a Schmidt telescope work?

Schmidt telescope, also called Schmidt camera, telescope in which a spherical primary mirror receives light that has passed through a thin aspherical lens, called a correcting plate, that compensates for the image distortions—namely, spherical aberrations—produced by the mirror.

What are Schmidt Cassegrain telescopes best for?

Their high f-ratio means they are not a wide-field telescope like their Schmidt camera predecessor, but they are good for more narrow-field deep sky and planetary viewing.

What are Schmidt telescopes used for?

A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930.

Are Schmidt Cassegrain telescopes good?

5 Best Schmidt Cassegrain Telescopes in 2022 – Reviews & Top Picks. Schmidt Cassegrain telescopes are powerful, compact instruments with loads of utility. Good products will have you seeing stars, while subpar units will only frustrate.

What is the difference between a Cassegrain and a Schmidt-Cassegrain telescope?

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.

What are the basic parts of a Schmidt-Cassegrain telescope?

The Schmidt-Cassegrain system consists of a zero power corrector plate, a spherical primary mirror, and a secondary mirror. Once light rays enter the optical system, they travel the length of the optical tube three times.

How big of a telescope do you need to see Saturn rings?

The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.

Can I see Pluto with a telescope?

Can I See Pluto With a Telescope? Yes, you can see Pluto but you’ll need a large aperture telescope! Pluto resides at the very edges of our solar system and shines only at a faint magnitude of 14.4. … The dwarf planet is 3,670 million miles away from the Sun and looks just like another faint star in your telescope.

Why do they put telescopes on high mountains or in space?

Most important, putting an observatory on a mountaintop means there’s less air to see through, so the “seeing” is better. On a mountaintop, there’s also less air above you to absorb light from the stars.

What type of telescope is a Dobsonian?

A Dobsonian is a reflecting telescope (uses a mirror, not a lens) in the same design as a Newtonian telescope (concave collecting mirror is at the rear of the telescope tube, eyepiece is on the side of tube, up near the front).

Who makes Schmidt Cassegrain telescopes?

There are two primary manufacturers of Schmidt Cassegrain Telescopes: Celestron and Meade, which are both well-respected brands within the telescope industry. SCTs are known for their long native focal ratios, usually around f/10.

What is the difference between Dobsonian and Newtonian?

The answer is that Dobsonian and a Newtonian can actually be the same thing. A Newtonian refers to the telescope optics, whereas a Dobsonian refers to Newtonian telescope with some specific features like an altazimuth mount and often thin mirrors. A telescope can be a Newtonian and also a Dobsonian at the same time.

Are Schmidt-Cassegrain telescopes good for astrophotography?

When it comes to imaging we have found the Schmidt-Cassegrain (SCT) type scopes are very good. Some astrophotographers prefer other types and they all have their benefits but SCT scopes are very versatile and are not cost prohibitive. Another type of telescope to consider is a Triplet Refractor.

What can you see with an 8 inch telescope?

The most distant galaxies that you will be able to see with an 8″ telescope will be about 50 to 100 million light years away e.g. M109 with apparent magnitude 10.3 at distance 83 ± 24 million light years. You’d just about be able to resolve M49. So the answer would seem to be “at least 72 million light years”.
