What are Schmidt-Cassegrain telescopes good for?
Schmidt Cassegrains are high-level all-purpose telescopes, ideal for viewing the moon, planets, and deep-sky objects. They are also ideal for astrophotography, using everyday DSLR cameras. Most come with computerized GoTo mounts and motorized object tracking.
Which is better Schmidt-Cassegrain or Maksutov Cassegrain?
In short, a Maksutov-cassegrain telescope is generally better for planet viewing due to the narrow and generally large focal ratios, however this also does compromise the astrophotography performance of Mak telescopes, which is an area Schmidt-Cassegrain telescopes don’t suffer nearly as much from whilst still having …
What is the difference between Dobsonian and Cassegrain telescopes?
Focal length – Dobsonians and reflector telescopes in general tend to have a short focal length, whereas Cassegrain telescopes have a long focal length. The longer the focus, the higher the magnification.
How does Schmidt Cassegrain 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.
Why is the Cassegrain telescope shorter?
Why are Cassegrain telescopes shorter than Newtonian reflecting telescopes? Many websites say this is because the effective focal length of the objective is increased by making the secondary mirror convex. This allows a Cassegrain telescope to be shorter than a similarly powered Newtonian.
What kind of optics does the Schmidt Cassegrain telescope use?
The CGX 1100 Schmidt-Cassegrain Telescope features Celestron’s premium StarBright XLT coated optics and the all-new state of the art CGX computerized equatorial mount.
Which is better Schmidt Cassegrain or VX 11?
The Advanced VX 11” Schmidt Cassegrain telescope is one of the most affordable and portable 11” telescopes; perfect for imagers and visual observers alike. The 11” optical tube offers 41% more light gathering than a 9.25” telescope.
Which is better CGX 1100 or 9.25 ” telescope?
With the optical tube assembly of the CGX 1100 weighing only 27.5 lb., this telescope is still portable enough to be taken to dark skies, and it has 89% more light gathering power than an 8″ telescope and more than 40% more than the 9.25″.
Which is the best 11 ” telescope on the market?
The Advanced VX (AVX) sets a standard in mid-level telescopes, providing many of the features found on Celestron’s most sophisticated German equatorial mounts at an extremely affordable price. The Advanced VX 11” Schmidt Cassegrain telescope is one of the most affordable and portable 11” telescopes; perfect for imagers and visual observers alike.
