The BRESSER Messier 6'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes.
Not only for beginners - also enthusiastic and experienced amateur astronomers love this high perfomance and compact telescope for traveling and to discover the night sky. The main goal of this telescope is the quick setup and the ease of use. Simply put the Messier 6'' Dobson telescope on a table in your backyard, point the telescope to your target object and you are ready to start your observation.
The Messier 6'' Dobson is almost pre-assembled ex factory which means you can start within minutes. With the included standard accessories (LED-finder, 25mm and 9mm Kellner eyepieces and Moonfilter) the telescope is ready for observing. The inbuild compass and circular level speeds up the telescopes orientation.
The optical diameter of 150mm (6'') does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. Finding and observing is much easier with that light gathering richfield telescope. Bresser also has equipped these dobsonians with a high quality parabolic main mirror which offers a much better scharpness and contrast than other telescopes with a simple spherical main mirror. In addition, this telescope has a particularly large secondary mirror of 55mm in diametre for ideal illumination of the image field.
The 6'' Dobsonian is also equipped with a large 2.0'' focuser, which allows the use of 2.0'' eyepieces with even larger fields of view. Due to the included eyepiece adapter 2'' to 1.25'', all 1.25'' eyepieces can of course be used.
The optical tube can easily be moved inside the tube rings in order to find the optimal balance and observing position. This is another virtue of this highly versatile telescope system: Remove the optical tube from the dobsonian telescope mount and use the optics on a equatorial mount - in minutes.

- Check the solar filter before every solar observation and ensure that it is not damaged. Hold it against a strong light source to detect any possible cracks and/or holes. Do not use the telescope for solar observation, even if the solar filter is only slightly damaged. In this case, contact the manufacturer for the appropriate replacement parts.
- Always use the included solar filter when observing the sun. Make sure it is correctly attached to the telescope according to the instructions. The use of the solar filter is only intended in connection with this telescope.
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Check the secure fit of the solar filter before each solar observation. An accidental detachment from the objective opening can lead to immediate and permanent eye damage and blindness.
- If the solar filter cannot be securely attached to the tube, improve the fit by placing several self-adhesive felt strips or similar between the solar filter and the objective opening. Never use the solar filter if it cannot be properly mounted on the telescope. In such a case, always contact our customer service first.
- Be extremely cautious when observing the sun. A brief look through the unprotected optics will immediately cause severe eye damage, potentially leading to complete blindness.
- Children should not look at the sun through the telescope, even with the filter properly installed. Never leave children unsupervised.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not observe the sun after eye surgeries or other eye conditions without prior medical consultation.
- Wrinkles/creases in the film are normal and do not indicate a product defect.
- Do not expose the device to high temperatures.
- BATTERY WARNING AND SAFETY Safe handling and use of batteries and accumulators Read and follow these instructions before using the battery or accumulator. To the extent permitted by law, failure to comply with these warnings and instructions may result in any damage caused to your product not being covered by the warranty. In this document, the term "batteries" also includes accumulators. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use supplied batteries. Use the battery SOLELY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries that appear to be damaged, swollen, or modified. Do not use batteries that are leaking, emitting a smell, swollen, melted, or showing dents, rust, cracks, or scratches. The battery should NOT be disassembled, crushed, punctured, shredded, or otherwise tampered with. The battery should NOT be exposed to liquids. Liquid may penetrate the battery's circuits, causing corrosion and compromising its safety. A wet or damp battery should NOT be dried with a device or heat source (e.g., hairdryer or microwave). The device or battery should NOT be placed near a heat source or direct sunlight. High temperatures can cause the battery to swell, leak, or malfunction. Examples include placing the device near a radiator, stove, kitchen appliance, iron, fireplace, or inside a vehicle or next to a window in direct sunlight. The battery should NOT come into contact with metal objects. If metal objects such as jewelry come into prolonged contact with the battery terminals, the battery may become very hot or catch fire. The battery should NOT be stored together with hazardous or flammable materials. Store the battery in a cool, dry, and well-ventilated area. The battery should NOT be inserted incorrectly when charging. MAKE SURE the battery compartment is empty, dry, and free of dirt before inserting the battery. The battery should NOT be charged in direct sunlight or at extreme temperatures. The battery must be charged at room temperature, typically between 20 °C and 26 °C (68 °F-79 °F). Charging may be temporarily suspended if the battery temperature exceeds 60 °C (140 °F). If the battery is hot but the temperature is under 60 °C (140 °F), the battery will still charge, but more slowly than usual. Avoid dropping the battery or the product with the battery inside. If dropped onto a hard surface, the battery or product may be damaged. If you suspect the battery might be damaged, replace it. Never leave your mobile hotspot plugged into the power supply for more than 24 hours to charge. Let the battery drain and then recharge it. Keeping your mobile hotspot plugged into a charger without draining the battery can damage the battery/device or affect performance. If a battery shows a significantly shorter runtime than when purchased, it has reached the end of its reasonable lifespan. We recommend replacing it. For optimal results and performance, batteries should be replaced after 12 months or earlier depending on usage. Follow local regulations for the disposal of used batteries. Do not throw the battery into fire or water.
