Bresser AC 102/1000 - Powerful refractor for Moon and Planets
The Bresser AC 102/1000 is a reliable telescope for anyone who wants to see the Moon, Jupiter or Saturn up close. With its 102 mm lens, it captures enough light to show bright, high-contrast images - without distracting reflections or color errors. The long focal length of 1000 mm makes it easy to see fine details, such as craters on the Moon or cloud bands on Jupiter.

Clear image with natural colors
The achromatic lens delivers a sharp and calm image. You'll see bright celestial bodies like Venus or the Moon without annoying color aberration. The f/9.8 aperture ratio ensures that your image remains sharp even at high magnifications - ideal for those who like to observe for long periods of time without shake or blur.
Hexafoc focuser for precise focusing
The sturdy Hexafoc Focuser offers a wide opening of 65 mm, so you maintain maximum light output. That means your images stay clear, even when using accessories or cameras. An optional 1:10 micro fine adjustment lets you adjust focus with extreme precision - perfect for those who want to get into photography later.
EXOS-1 mount - stable and reliable
The EXOS-1 mount keeps the telescope firmly balanced. You can track smoothly without vibrations, even at higher magnifications. This mount can carry up to 7 kg, so you can add accessories without worry. Want automatic tracking? Simply add a motor for RA tracking and enjoy relaxed observing sessions.

Ready to use - everything you need in one set
The Bresser AC 102/1000 comes with a 26 mm eyepiece, 6×30 viewfinder, zenith mirror, sunscreen, and oculairadapter. So you can start observing right away - whether you want to study the Moon or take a first look at the Orion Nebula.
