Product Overview

The BRESSER 6-inch 150/1200mm Planetary Dobsonian Telescope is a high-quality Newtonian reflector designed for planetary and deep-sky observation. It features a 150mm aperture and 1200mm focal length, providing a focal ratio of f/8. The telescope is mounted on a stable, user-friendly Dobsonian base, making it an excellent choice for both beginners and experienced astronomers.

Safety Information

DANGER: Never look directly at or near the sun with this telescope without a properly installed, undamaged solar filter. Doing so will cause immediate and permanent eye damage or blindness. Always inspect the solar filter for cracks or holes before every use. Never leave the telescope unattended, especially around children.

Assembly

The telescope requires assembly of the Dobsonian base. Use a soft surface to prevent scratching. Ensure the base components are securely fastened using the provided hardware. The tube is attached to the base using altitude wheels, which must be balanced correctly to ensure smooth movement and prevent the tube from tipping.

Operation

Before observing, allow the telescope to acclimate to the outdoor temperature for approximately 90 minutes to prevent "tube seeing" effects. Use the included 25mm and 5mm eyepieces to adjust magnification. The telescope is operated by manually moving the tube on its base. For finding objects, align the included 6x30 finder scope with the main telescope during the day using a distant, stationary object.

Maintenance and Care

Keep the optics clean by avoiding unnecessary contact. If cleaning is required, use a specialized blower to remove dust. Fingerprints can be cleaned with a mixture of isopropyl alcohol and distilled water using a soft, lint-free cloth. Store the telescope in a dry, dust-free environment. Periodically check the collimation of the mirrors to ensure optimal image quality.

Troubleshooting

If images appear blurry, ensure the telescope has reached thermal equilibrium and that the focus is adjusted correctly. If the telescope is difficult to move, check the Teflon gliders on the base; they should be kept clean and dry. For persistent issues, contact the manufacturer's service center.

Disposal

Dispose of packaging materials and the device in accordance with local environmental regulations and waste management guidelines.
