Teleskop AC 70/900 EQ-1

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

An achromatic is a refracting telescope (refractor), which consists of two lenses. It is the classic refractor design.

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.

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

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

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.

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

A red LED dot is projected onto a disc.

Telescopes for experienced observers, but also for ambitious beginners.
