Bresser Telescope AC 90/900 Messier Nano AZ (64991)

The traditional company Bresser offers telescopes under the Messier brand, providing an excellent price-performance ratio for ambitious beginners. These Messier telescope systems are expandable and retrofittable, making them suitable for use well beyond the initial entry point.

Bresser Messier R-90
The MESSIER R-90 is an ideal telescope for beginners entering the world of astronomy. Its 90 mm aperture gathers 200 times more light than the naked eye, allowing you to observe craters, valleys, and rims on the Moon from nearly 400,000 km away—offering a view as if you were right there!

This telescope provides highly detailed views not only of the Moon but also of other celestial objects. Observe Saturn's ring divisions millions of kilometers away or explore Jupiter's Great Red Spot, a massive atmospheric storm. Witness seasonal changes on Mars or spot Venus' crescent shape. The MESSIER R-90 delivers images that are significantly brighter and clearer than those seen through Galileo Galilei’s telescope during his historic discoveries almost 400 years ago.

Nano AZ Mount
The Nano AZ mount is a single-arm mount that is quick to set up and simple to operate. It functions much like a photo tripod for ease of use. The mount supports telescopes weighing up to 3.5 kg and is compatible with all telescopes featuring Vixen standard prism rails.

The stainless-steel tripod provides a stable base for the mount, ensuring steady and reliable observations.
