Bresser AC 90/1200 - Classic precision for moon and planet lovers

The Bresser AC 90/1200 Messier OTA is a true classic among lens telescopes. With its long focal length and sharp optics, it is made for those who want to explore the Moon and planets in crisp detail. Perfect for the serious beginner or the advanced observer who loves tight contrast and flawless images.

Razor-sharp images even at high magnification

The 90 mm lens captures about 200 times more light than the naked eye. This allows you to see fine crater structures on the Moon, the rings of Saturn and the cloud bands of Jupiter clearly and brightly. The long focal length of 1200 mm provides high magnifications without loss of sharpness, so you can study every detail calmly.

Designed for tranquility and contrast

The fixed dew hood blocks stray light and prevents dew formation - ideal for nights with humid air. This keeps your image clear and contrasty even when the temperature drops. The aluminum tube feels sturdy but is light enough to move easily.

Reliable construction for years of use

The Bresser 90/1200 Messier is built to grow with your experience. The stable tube construction and classic focuser make it reliable for many years of observations. Add accessories later to look even deeper into the universe.

What to expect

✓ Moon: extremely sharp, lots of detail in craters and mountains
✓ Planets: clearly visible rings, cloud bands and color contrasts
✗ Deep-sky: limited by the long focal length
✗ Astrophotography: not suitable without additional adjustments
