Bresser AC 127S/635 EXOS-2
Compact design, powerful image
The Bresser AC 127S/635 EXOS-2 is built for those who want to look big without heavy lifting. Thanks to its short tube and fast f/5 aperture, this telescope captures a lot of light in a short time. So you'll see bright, wide fields of view - perfect for the Milky Way, the Orion Nebula or Andromeda.
Bright, colorful and sharp
The 127 mm aperture lets in plenty of light so nebulae, star clusters and planets become visible in full detail. The special four-lens superachromatic construction reduces color aberrations and delivers vivid, high-contrast images. You get deep colors and sharp edges even at high magnification or photography.
Sturdy yet easy to handle
The short length makes the telescope less prone to vibration and easy to move. The balance remains stable even when adding accessories. Ideal for both home and dark observation sites.
Precise focusing with Hexafoc
The large Hexafoc focuser (64 mm aperture) makes focusing smooth and precise. Optionally, add the 1:10 fine adjustment for even more control - useful at high magnifications or while shooting.
Reliable EXOS-2 mount
The EXOS-2 mount offers stability and precise tracking. Thanks to double ball bearings in both axes, the telescope moves smoothly without play. This keeps your image steady and sharp, even during long observations or photo shoots.
Smart GoTo System
The GoTo system does the search work for you. At the touch of a button, it finds and tracks more than 100,000 celestial objects. The backlit manual controls are easy to use, even in the dark. That way you spend more time looking than searching.
Complete package, ready to use
Everything you need is included: eyepiece, viewfinder, solar filter, tripod and smartphone adapter. Within minutes, you'll be ready to explore the sky - from sunspots to distant galaxies.
