Product description:

The AC 80/350 telescope provides you with excellent views of the Moon and planets. It will also show you the brighter star clusters and nebulae. This refractor is a Fraunhofer-type achromat, which means that the objective lens consists of two elements - one made of crown glass and the other of flint glass. This combination reduces the unavoidable chromatic aberration of refractor telescopes. The two lens elements are separated by a narrow air gap and not glued together, as this would lead to significant deterioration of the optical properties over time.

This compact refractor telescope is ideal for travelling.

It is not only important which telescope you buy, but also where you buy it.

We provide extra help:

We are a leading telescope dealer and know these instruments like the back of our hands.
We are always very happy to offer our assistance after your purchase, should you encounter any problems with your telescope’s setup or operation.
Our ‘Telescope Basics’ booklet - an 80-page beginner's guide for our telescopes – is provided free of charge with every telescope we sell.

1.25'' eyepieces 1.25'' eyepieces X 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). Click to read more...	20mm, 10mm
Deviating optics Erecting systems X 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. Click to read more...	1.25", 90° star diagonal
