Schmidt Cassegrain Telescopes

With the choice of a Schmidt-Cassegrain telescope (also known as an SCT), you’re in excellent company. It has been one of the most popular optical designs in the world for decades, and it’s not hard to see why! An SCT offers a remarkably large aperture and a long focal length in a tube that is many times shorter and lighter than a comparable reflector or refractor. Plus, it’s the most versatile system on the market: with the right prism, you can use it just as easily for daytime landscape viewing as for nighttime astronomy. Are you looking for the ultimate, compact all-rounder that scans the sky fully automatically for you? Then discover our iconic Celestron NexStar SE and Evolution systems and experience for yourself why the SCT is the king of versatility!

Schmidt-Cassegrain telescope: Celestron's all-rounder

A Schmidt-Cassegrain telescope (SCT) bends the light using a thin corrector plate and two mirrors, allowing a 2000 mm focal length to fit into a 45 cm tube. At f/10, the design is sharp on the Moon and planets, and with a 0.63x reducer, it becomes an f/6.3 deep-sky instrument. No other type of telescope offers such versatility per kilogram. In Europe, Schmidt-Cassegrain is almost synonymous with Celestron, and we carry that entire line, from the NexStar 5SE to the C11 on a CGEM II mount.

Which series suits you?

  • NexStar SE (5, 6, and 8-inch). Fork mount with GoTo, single arm, set up in five minutes. Visual and for planetary photography. The 8SE is the classic.
  • NexStar Evolution (6, 8 and 9.25 inch). Same fork mount with built-in battery and WiFi. Control via the SkyPortal app. No more cables in the field.
  • Advanced VX-sets. The same tubes on an equatorial GoTo mount: C6, C8, C9.25 and C11. For those who want to create long exposures.
  • CGEM II sets. The heavier mount for the C8 to C11 in a fixed observatory.
  • EdgeHD. The same tubes with built-in field correction, for photography right into the corners of a large sensor.

Our recommendations

  • Visual and entry-level: NexStar 6SE. 150 mm, GoTo, two-handed carry.
  • The classic: NexStar 8SE. 203 mm opening in a package that fits in a small car.
  • Photography: C8 on Advanced VX, with a 0.63x reducer for deep-sky.

For whom yes and for whom no

Well: anyone who wants one telescope for everything, who needs to stay compact with a large aperture, and who wants to do astrophotography later. Not: anyone looking for the cheapest route to a large aperture (choose a Dobson) or those who primarily want to shoot wide-field deep-sky (choose a short APO refractor).

Accessories: A dew shield is required; a 0.63x reducer widens the field of view and shortens the focal length; and a 2-inch zenith mirror with a wide-angle eyepiece gets the most out of a C8 and larger telescopes. Everything about the merk on the Celestron merk Page. Shipping throughout Europe.
