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 sharpness and contrast than other telescopes with a simple spherical main mirror. In addition, this telescope has a particularly large secondary mirror for ideal illumination of the image field.
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. 
This telescope is setting a new standard in usability, versatility and performance in its price class.
Please Note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.
