Meade Telescope AC 90/900 Polaris EQ

Item Description:


The Polaris telescopes from Meade offer small to medium optics with lots of accessories on a parallactic mount at a very good price.

With this type of mount, an axis is aligned with the north star (Polaris). This polar alignment means that the telescope only has to be rotated continuously around an axis to compensate for the sky rotation. This is not only convenient, it also makes orientation easier with the help of a star map.

The tracking is done by hand using a handy rotary knob that is connected to a flexible shaft. A motor is also available as an option.

Each Polaris telescope is supplied with a tubular steel tripod for better stability.





Optics AC 90/900: This optics has an achromatic lens. Most color errors are already corrected by a combination of two lenses. When observing, you no longer have as many annoying color fringes as is the case with normal Fraunhofer refractors. The opening ratio of 1:10 causes an additional. Overall, this optic is ideally suited for beginners to carry out initial experiments with sky observations. Even children get along quickly with this relatively uncomplicated look. Discover a new world that opens up to you at night.

The advantages at a glance:

hardly any color defects
easy operation
compact, easily transportable tube
Lens telescopes like this are also particularly suitable for children, because the deep eyepiece view at the telescope end can be reached without a ladder. In addition, the operation is very intuitive and no adjustment has to be made. A telescope for beginners and the whole family!
