Bresser AC 102S/600 - Compact, Bright and Ready for the Night Sky
The Bresser AC 102S/600 is an ideal telescope for those who want a clear and wide image without the hassle. Thanks to its 102 mm aperture, you will not only see the Moon and planets in detail, but also nebulae and star clusters that normally remain invisible to the naked eye. With its short focal length of 600 mm, it delivers a wide field of view, perfect for wandering the Milky Way and admiring vast deep-sky objects.

Clear image, great contrast
This telescope captures a lot of light, allowing you to see fine details - the cloud bands of Jupiter, the craters on the Moon or the dust veils in the Orion Nebula. Thanks to its high resolution, images remain sharp even at magnifications of up to 200x.
Perfect for comet hunters
The Bresser 102S/600 is known as a true “comet finder.” Its wide field of view makes it easy to track bright comets, including the coma and much of the tail. Whether you are a novice observer or just want to see something special, this telescope lets you experience the beauty of the solar system up close.
Precise focusing with Hexafoc
The robust Hexafoc Focuser with a free aperture of 64 mm ensures smooth, precise focusing. Want even more control, such as for photography? Then add a 1:10 micro fine adjustment to allow razor-sharp focus.
Sturdy EXOS-1 mount
The EXOS-1 mount offers stability and precision even at higher magnifications. It carries optics up to 7 kg while remaining vibration-free. For those who want to observe longer or take photos, the mount can be expanded with an optional motor for automatic tracking.

Easy to use and delivered complete
Everything you need to get started is included: a 26 mm eyepiece, 6×30 viewfinder, 2″ to 1.25″ adapter and sturdy steel tripod. Within minutes, you'll be ready to explore the night sky.
