Bresser Telescope AC 90/1200 Messier EXOS-1 (59229)

The Messier series by Bresser provides telescopes with an excellent price-performance ratio, making them perfect for ambitious beginners. These telescopes are designed to be expandable and retrofittable, ensuring they remain useful as users advance in their astronomy journey.

AC 90/1200 Optics: A High-Quality Refracting Telescope for Planetary Observation
This telescope is an ideal choice for starting out in astronomy. Its 90mm aperture gathers approximately 200 times more light than the naked eye, providing sharp and detailed images of celestial objects.

With the AC 90/1200, you can observe craters, valleys, and grooves on the Moon from a distance of nearly 400,000 km as if you were up close. It also offers breathtaking views of Saturn's rings millions of kilometers away and allows you to see Jupiter's "Great Red Spot," a massive storm in its atmosphere. You can track seasonal changes on Mars or observe Venus's crescent with ease.

The AC 90/1200 captures several times more light than the telescope Galileo Galilei used to make his historic discoveries nearly four centuries ago. Its permanently installed exchangeable protective cap reduces dew formation and blocks stray light, enhancing image contrast even further.

Bresser EXOS-1 Mount
The EXOS-1 mount is designed for smaller optics and can support up to 7 kg without vibration or instability. It provides a stable platform for precise observations and can be optionally upgraded with a motor for the RA-axis to improve tracking capabilities.
