Teleskop N 150/1200 Explorer 150PL EQ3-2

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.

Fan for a quicker alignment of the mirror temperature to the ambient temperature.

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

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

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

Is a type of mount set-up, whereby one axis is aligned parallel to the axis of the Earth.

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 mini telescope used to locate a celestial object. There are optical finders and red dot finders.

Equatorial mount for small to medium-sized telescopes.

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

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