Bresser AC 90\/500 - Compact wide-angle telescope with GoTo convenience<\/strong><\/p>\n\n\n\n

The Bresser AC 90\/500<\/strong> is built for those who want to explore the night sky without complicated settings. With its bright 90 mm lens, it captures enough light to clearly show star clusters, the moon and even bright nebulae. The short focal length of 500 mm provides a wide field of view, so you can see more sky in one view - perfect for exploring the Milky Way or tracking shooting stars.<\/p>\n\n\n\n

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

Wide view, clear image<\/strong>
Thanks to the achromatic design, your image remains sharp and rich in contrast. Stars appear as fine points, not hazy specks of light. The large aperture allows plenty of light to enter, so even fainter objects remain visible. So you enjoy clear images even in low moonlight.<\/p>\n\n\n\n

Smart GoTo mount with EXOS-2 stability<\/strong>
The sturdy EXOS-2 GoTo mount<\/strong> keeps your image steady and precise. No frustration with manual searching - at the touch of a button, the GoTo system automatically targets more than 100,000 objects<\/strong>. Planets, galaxies and nebulae appear naturally in view. And thanks to the stable steel tripod, your telescope stays perfectly aligned, even in light wind or uneven ground.<\/p>\n\n\n\n

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