Celestron telescope NexStar 90 GT

Quality is timeless - we are pleased to be able to offer the robust NexStar GT mount from Celestron again, in an updated version with the German-speaking NexStar + hand controller.

The NexStar 90 GT is a high-magnification, computer-controlled telescope that Celestron produced especially for the Baader Planetarium in Europe. It offers all the good properties that can be expected from a classic lens telescope: a sharp image and the high magnification required for the moon, planets and star clusters. Unlike many inexpensive telescopes, the image quality was not sacrificed for a compact design. With the appropriate AstroSolar filter, it is also suitable for daytime sun observation.

The compact Nexstar GT mount contains the same technology as the large computer-controlled Celestron mounts: you only have to control three bright stars with the German-speaking hand controller, then the telescope is automatically tracked to the stars, moves to all the destinations you enter, and even makes observation suggestions!

So you can easily find and observe the wonders of the cosmos in the telescope.
