Product description

More about the series Messier...

The traditional company Bresser offers telescopes for ambitious beginners at an excellent price-performance ratio under the name Messier. The Messier telescope systems are expandable and retrofittable, so they can be used far beyond the initial entry point.

Dobsonian telescopes are among the most practical instruments in astronomy. They are of simple construction and yet a brilliant idea. They essentially consist of two parts: firstly the optics, which in most cases is a solid tube or truss tube design; and secondly the mount, a wooden box (also called a 'rocker box') which sits on the ground and into which the telescope is inserted. This design allows you to begin observing sessions immediately without first having to spend time setting up and aligning a complicated mount. The basic idea of the Dobsonian design came from the wish to have a big telescope at a low price, a wish that has succeeded brilliantly. A true fan base has developed since the invention of the Dobsonian telescope which is dedicated to these instruments and their fascinating simplicity and to the idea of 'high performance at low price'.

The 254/1270 optics: With the 254-millimetre diameter optics, you can already look far out into the universe and observe globular clusters, nebulae and galaxies. This telescope reveals details and structure in most deep-sky objects: Globular clusters are resolved into individual stars and gas nebulae, which smaller instruments can only faintly make out.
Other advantages of the optics:

  • Diffraction limited: Strehl > 0.8
  • 9-point mirror cell
  • Main mirror made of special glass with low thermal expansion: H-PZ33 borosilicate

Many experienced observers prefer Dobsonian telescopes in the 10-inch class (254mm). The optics have considerably greater luminous intensity than the 8-inch models, but the telescope is still manageable: 10-inch models are truly portable and have a viewing height for which a simple stool is enough, rather than a height-adjustable astro-chair.

The excellent large Hexafoc focuser has an aperture of 64mm making it impossible to notice any shading from the focuser tube, even with large widefield eyepieces.

Special advantages of the Messier series Dobsonian telescope:

  • The Rockerbox is assembled with metal quick-release connectors that allow it to be disassembled and reassembled in minutes without the need for a cordless screwdriver.
  • The device uses a new 2.5" focuser. It is highly rigid and free of any shifting.
  • The optical tube sits in a pair of pipe clamps that support the large altitude wheels on the sides. This means that the tube can also be used on a parallactic mount without any problems and can also be rotated along its longitudinal axis to provide the ideal eyepiece view in any position. By moving the tube within the tube clamps, the Dobsonian can be optimally balanced.

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
  • We also provide an edition of the exciting astronomy magazine, “Sterne und Weltraum” with each telescope.
