Apochromatischer Refraktor Pro APO AP 140/910 Triplet ED FCD-100

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.

Including eyepiece, but excluding dew cap.

FMC stands for fully multi-coated.

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.

Optical aid to correct aberrations.

The Omegon ProApo series are apochromatic refractors with ED lenses in a doublet or triplet design.

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.
