Teleskop ACF-SC 203/2032 UHTC LX65 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.

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.

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

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.

Telescopes for safe solar observing.

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.
