Bresser AC 90/500 - Compact wide-angle telescope with GoTo convenience
The Bresser AC 90/500 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.
Wide view, clear image
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.
Smart GoTo mount with EXOS-2 stability
The sturdy EXOS-2 GoTo mount 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. 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.
Ready to use - unpack and observe
The Bresser AC 90/500 comes with everything you need: a 26 mm eyepiece, 6×30 viewfinder, 90° zenith mirror and a handy accessory holder. Within minutes, you'll be ready to observe.
