Bresser AC 90/500 - Compact widescreen telescope with stable EXOS-2 mount
The Bresser AC 90/500 Messier with EXOS-2 mount is made for those who want to explore the night sky wide and clear. With a 90 mm aperture, it captures more than enough light to beautifully display star clusters, nebulae and the Milky Way. The short focal length of 500 mm gives you a wide field of view, so you catch more sky in one glance - ideal for exploration and learning to navigate among the stars.
The images are sharp and high-contrast, perfect for beginners and advanced users looking for a light, fast telescope. Point it at the moon and enjoy sharp craters and deep shadows. Or view Saturn's rings and Jupiter's cloud bands with surprising detail.
The EXOS-2 mount takes this telescope to the next level. It is sturdy, precise and built to minimize vibration, so your image remains stable - even at high magnifications. Thanks to radial bearings, the telescope moves smoothly and you can track objects easily. Add a tracking motor later if you want to start simple astrophotography.
The aluminum tube is light but sturdy, and the included accessories get you started right away. Within minutes, you'll be outside with a fully equipped telescope ready for stargazing.
