Schmidt-Cassegrain Teleskop SC 203/2032 NexStar 8 SE GoTo

The aperture indicates the diameter of the objective lens or the mirror.

This is the distance between the objective lens or mirror and the focal point.

Most telescopes are made of steel, aluminium or carbon fibre.

The telescope’s magnification should not exceed this factor, because otherwise the image will appear weak and dark.

Including eyepiece, but excluding dew cap.

Describes the brightness of a star or point-shaped object, which can still just be distinguished by the telescope. The naked eye, for example, can make out stars with a magnitude of up to 6.

Are mainly differentiated between equatorial and altazimuth. A special type of altazimuth mount is the Dobsonian mount.

These astronomical mounts are particularly lightweight and compact.

A telescope always displays an object upside down. This law of optics can only be compensated for by an erecting system. Erecting lenses, diagonal mirrors or Amici prisms provide you with an upright image. Diagonal mirrors provide an upright but back-to-front image and Amici prisms provide an upright and right-sided image.

Excellent travel telescopes thanks to their extremely compact design.

Telescopes for experienced observers, but also for ambitious beginners.
