Bresser Telescope AC 90/1200 Messier EXOS-2 GoTo (59231)

Bresser, a traditional company, offers telescopes for ambitious beginners under the Messier brand, known for their excellent value and performance. Messier telescope systems are designed to be expandable and upgradeable, making them suitable for long-term use beyond the entry level.

AC 90/1200 Optics:
This is a high-quality refracting telescope, ideal for planetary observation. With a 90 mm aperture, it collects about 200 times more light than the unaided human eye, making it an excellent choice for those starting out in astronomy.

Observe the Moon’s craters, valleys, and ridges from nearly 400,000 km away in remarkable detail. The AC 90/1200 also allows detailed views of Saturn’s rings, Jupiter’s “Great Red Spot,” the changing seasons on Mars, and the phases of Venus. This telescope captures significantly more light than the instrument used by Galileo for his famous discoveries.

A permanently installed, exchangeable protective cap reduces dew formation and blocks stray light from the sides, increasing image contrast.

Bresser EXOS-2 Mount:
The EXOS-2 mount is robust and has a high load capacity, supporting up to 13 kg visually and 10 kg for photography. Double radial ball bearings ensure smooth operation, and the optimized right ascension axis minimizes play. This stable and precisely engineered mount is also suitable for those beginning astrophotography. An optional two-axis motorized control can be added.

• Strong three-legged steel tripod

GoTo System for EXOS-2:
The GoTo system makes it easy for beginners to find and track celestial objects. With a press of a button, the system automatically moves the telescope to the selected planet, nebula, or galaxy and tracks it. The database contains more than 100,000 objects, allowing users to observe or photograph even faint celestial targets without time-consuming manual searching.
