Apochromatischer Refraktor AP 80/480 Series 6000 LX85 GoTo

Describes the exact structure of the telescope thereby further subdividing the different types of telescope.

Refractors with little chromatic aberration.

This is the distance between the objective lens or mirror and the focal point.

The ability of the optic to discern the fine detail of objects that are close together.

Light-gathering capacity of the telescope compared to the eye.

The weight of the tube is critical for the correct choice of mount.

Including eyepiece, but excluding dew cap.

A lens telescope that almost completely corrects chromatic aberration. It consists of three lenses and offers very high optical performance thanks to its design.

Focusers are available in 1.25" or 2" formats. Many 2" focusers also have a 1.25" adapter.

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.

The Global Positioning System simplifies the initialisation of a computerised control system.

With the computer control, setting up the telescope is very accurate and easy.

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 experienced observers, but also for ambitious beginners.
