Teleskop N 200/1000 Explorer 200P OTA

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.

Here, the construction type means the geometric shape of the primary mirror.

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

A Crayford focuser is a ball bearing guided friction drive and allows a very precise adjustment of the focus.

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

An OTA is an optical tube without a mount. It is short for optical tube assembly.

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

Telescopes with Newtonian optics. The amateur astronomy workhorses!

Telescopes for experienced observers, but also for ambitious beginners.

Telescopes suitable for a fixed mount, whether that is in the garden or an observatory.
