There are basically two different types of telescope. A distinction is made between refractor (lens) and reflector (mirror) telescopes.

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

Is the ratio of the aperture to the focal length of a telescope.

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.

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

Focusers are available in 1.25" or 2" formats. Many 2" focusers also have a 1.25" adapter.

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.

Describes the exact construction of the particular mount and thereby further subdivides the different types of mount.

Eyepieces are needed for observing. Depending on the focal length, you achieve a certain level of magnification.
The specification 1.25" refers to the diameter of the connector (1.25" = 31.8 millimetres).

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.

Fork-mounted telescopes with computer control for beginners and those upgrading.

Telescopes for safe solar observing.

Telescopes that are supplied as a complete system and are easy to operate.
