The Polaris telescopes from Meade offer small and medium optics with numerous accessories in a equatorial mount at a very good price.

In mounts of this type one of the axes is aligned with the North Star (Polaris). Thus, the telescope only needs to trace a continuous rotation in one of the axes to compensate for the Earth's rotation. In addition to being convenient, this makes it easier to navigate the sky with the help of a celestial chart.

Tracking is carried out manually through an accessible wheel that is attached to a flexible shaft . In any case, a motor available separately can be attached.

And to provide them with better stability, all Polaris telescopes are supplied with a steel tube tripod .



The optical system AC 90/900:

This optical system is equipped with a achromatic objective. The combination of two lenses corrects most chromatic errors. During observation, there are not as many disturbing chromatic fringes as in the case of conventional Fraunhofer refractors. The aperture ratio of 1:10 also supports this effect. Overall, it is an ideal instrument for beginners to undertake their first astronomical excursions into the sky. Even children soon know how to use this uncomplicated optical system. Discover a new world that invites you at night.

The advantages at sight:

  • hardly any chromatic errors
  • easy to use, even for children
  • compact tube, easy to transport

Lens telescopes like this one are also Perfect for children , as they can enjoy deep vision through the eyepiece at the end of the tube without the need for a ladder. Furthermore, its handling is very intuitive and does not require adjustments. This is an ideal telescope for beginners and the whole family!

The equatorial mount EQ-1 with tight counterweights. Only with this type of mount is it possible to accurately follow an astronomical object. Through the Practical flexible trees , you can synchronize the movement of an object with the field of view.

Optionally available: DVD with AutoStar Suite® software Astronomer edition . This Windows program includes more than 10,000 celestial objects for you to plan your observations and even print sky charts.
