Bresser Refractor GoTo Telescope 80/400 Automatic

Overview of the Bresser Refractor GoTo Telescope 80/400 Automatic

The Bresser Refractor GoTo Telescope 80/400 Automatic is a versatile, entry‑to‑intermediate level refracting telescope designed for both beginners and more experienced astronomers. With its compact 80 mm objective lens and 400 mm focal length, it delivers a balanced combination of image quality, portability, and ease of use.

Key Optical Characteristics

• Objective Diameter: 80 mm – provides ample light gathering for clear views of planets, the Moon, and bright deep‑sky objects.
• Brennweite (Focal Length): 400 mm – offers a moderate field of view suitable for planetary observation while still allowing decent magnification on a standard tripod.
• Magnification: 160× – achieved with the included 2.5 cm eyepiece, this level of magnification is ideal for detailed lunar craters and planetary surface features.
• Optical Design: Refractor – ensures sharp, high‑contrast images with minimal chromatic aberration thanks to Bresser’s quality lens coatings.

Mechanical Construction and Build Quality

The telescope is constructed from aluminium, giving it a lightweight yet sturdy frame that resists corrosion and can withstand regular use. The body finishes in a sleek black color, providing a professional look while reducing glare on the optical path.

Mounting and Stability

• Tripod Included: A robust tripod is part of the package, allowing quick setup and stable tracking during observations.
• Höhenverstellbar (Height Adjustable): The mount can be raised or lowered to accommodate different user heights and viewing angles, enhancing comfort during extended sessions.

GoTo Automation Features

The telescope’s automatic GoTo system is a standout feature that simplifies locating celestial objects. By connecting the telescope to a computer or tablet via USB, users can access an extensive database of stars, planets, and deep‑sky targets. The motorized mount automatically slews to the selected object, making it especially useful for:

• Newcomers who may find manual pointing challenging.
• Intermediate observers looking to quickly switch between targets without tedious alignment.
• Educational settings where rapid demonstration of multiple objects is desired.

Power Requirements and Battery Management

The GoTo system operates on standard AA batteries (Mignon). A total of six batteries are required to power the motors, electronics, and any connected devices. This configuration allows for:

• Portable operation without needing a mains outlet.
• Extended observation sessions by swapping out depleted batteries.
• Low maintenance thanks to widely available battery types.

User Experience and Target Audience

The telescope is specifically marketed toward the Einsteiger / Fortgeschrittene (beginner to advanced) demographic. Its combination of:

Typical Observation Scenarios

• Lunar Exploration: With 160× magnification, users can observe Mare Imbrium, Tycho, and the rugged highlands.
• Planetary Viewing: Jupiter’s Great Red Spot, Saturn’s rings, and Mars’ polar caps become accessible with clear, crisp images.
• Bright Deep‑Sky Objects: The Orion Nebula (M42), the Pleiades star cluster, and the Andromeda Galaxy are all within reach for detailed study.

Maintenance Tips

To keep the telescope performing at its best:

• Clean the objective lens gently with a microfiber cloth after each use to remove dust and fingerprints.
• Store the telescope in a dry, cool environment when not in use to prevent moisture buildup.
• Check battery contacts regularly for corrosion or loose connections that could affect GoTo performance.

Conclusion

The Bresser Refractor GoTo Telescope 80/400 Automatic delivers a well‑balanced package of optical clarity, mechanical reliability, and user-friendly automation. Its thoughtful design caters to both newcomers eager to explore the night sky and seasoned observers seeking a dependable, portable system for detailed planetary and deep‑sky studies.
