Maksutov Teleskop MC 127/1900 PE UHTC ETX-125 GoTo

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.

There are basically two different construction types: the rack and pinion focuser and the Crayford focuser.

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).

Compact telescopes with computer control (GoTo).

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