Dobson Telescope N 150/1200 Messier DOB

Under the name Messier, the traditional Bresser company offers telescopes for ambitious beginners with an excellent price-performance ratio. Messier telescope systems are expandable and retrofittable, making them useful well beyond the initial steps.

Dobsonian telescopes are among the most practical instruments in astronomy. They are simple and great in construction. They consist of two essential parts: firstly the optical system, in most cases of Newtonian construction, solid tube or lattice. Secondly the mount, a wooden box (also called "rockerbox"), placed on the ground to place the telescope. You can immediately start observing, you don't have to do complicated positioning and adjustment of the mount. The fundamental idea of ​​the construction was to offer the optical system of a telescope at an economical price. An idea realized successfully. Since the invention of the Dobsonian telescope, a true community of enthusiasts has developed who appreciate these instruments and their fascinating simplicity, according to the motto "big potential, small price".

The N 150/1200 optical system:

This Dobsonian instrument has a diameter of 150 mm (6") and a focal length of 1200 mm. It has an aperture ratio of f/8. This optical system offers a considerable light output of 460x. Under a dark sky you can already observe stars with limit values ​​of up to 12mag. With an aperture of 150mm you can already see deep space objects, which has not been possible with less powerful instruments. The frames of the main mirror are very slender and therefore reduce luminous fractions. of the optical system amounts, due to the diameter of the main mirror (34.5 mm), to about 22.5%.

The 2" telescopic eyepiece tube is characterized by the smooth movement of its components. It has a .125" reducing sleeve. The finder scope is equipped with a reticle and offers you the option of finding even dim objects.
