Bresser AC 90\/500 - Compact widescreen telescope with stable EXOS-2 mount<\/strong><\/p>\n\n\n\n

The Bresser AC 90\/500<\/strong> Messier with EXOS-2 mount<\/strong> 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.<\/p>\n\n\n\n

\"Bresser<\/figure>\n\n\n\n

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.<\/p>\n\n\n\n

The EXOS-2 mount<\/strong> 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.<\/p>\n\n\n\n

\"Bresser<\/figure>\n\n\n\n

What to expect<\/strong>
\u2713 Moon: detailed craters and mountains in high contrast.
\u2713 Planets: cloud bands, rings and polar caps clearly visible.
\u2713 Deep-sky: open star clusters and bright nebulae in their full glory.
\u2713 Ease of use: quick set up, stable image and intuitive operation.
