How many mm is a good telescope?

How many mm is a good telescope?

The aperture’s diameter (D) will be expressed either in millimeters or, less commonly, in inches (1 inch equals 25.4 mm). As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more.

What was the largest telescope Celestron ever produced?

The CGE Pro 1400 Schmidt-Cassegrain Telescope is part of Celestron’s “Top-of-the-Line” German Equatorial mounted astronomical telescopes. With over three times the light gathering power of an 8” telescope, this observatory-class instrument is Celestron’s largest optical system in its class.

How does Schmidt Cassegrain telescope work?

Schmidt-Cassegrain telescopes are a catadioptric design, meaning they use both lenses and mirrors. It is reflected from a concave primary mirror at the back of the scope which focuses the light to the front of the telescope where it is reflected again by a smaller, convex secondary mirror.

Is 70 mm telescope good?

However, a 70 mm refractor (which collects 36% more light than a 60mm telescope) is considered by many amateur astronomers to be the minimum size for a good quality beginner refractor telescope. It is acceptable for observing bright objects like lunar details, planets, star clusters, and bright double stars.

Is a 80mm telescope good?

80MM Large Aperture Telescope is a perfect telescope for adults and kids to use together with bright image quality and high magnification power. Very suitable for beginners to explore the vast sky, like the moon, the planet, star clusters and fog and so on.

What is a Schmidt Cassegrain telescope good for?

Schmidt Cassegrain Telescopes come in a wide variety of prices. On the lower end, SCTs are usually paired with a go-to mount for beginners. These are great telescopes for observing small objects like the planets and craters on the moon.

What are Schmidt Cassegrain Telescopes best for?

They are also well-suited to a number of applications including photography and terrestrial observing as well as stargazing. Most new SCTs are computerized, adding to their ease of use and portability. Schmidt-Cassegrain telescopes are a catadioptric design, meaning they use both lenses and mirrors.
