Description
The Bresser Messier 8" Dobson telescope is a Newtonian reflector telescope with a 203 mm diameter parabolic main mirror and an innovative 2.5'' HEXAFOC focuser, designed for visual observations of the night sky and the Sun. The telescope provides access to a wide range of celestial objects - from details of the lunar relief and planetary disks to distant galaxies, nebulae and globular star clusters. Among the key features of the model are diffraction-limited optics with a Strehl index >0.8, a rigid HEXAFOC focuser with a gear transmission that does not shift even under the weight of heavy equipment, as well as a convenient Rockerbox-type Dobson mount with metal connectors that is quickly assembled and disassembled. The telescope is suitable for both beginners and experienced observers who appreciate high-quality optics and a reliable design. The kit includes an objective solar filter, which makes the instrument versatile for day and night observations.
Purpose: Deep-Sky observations, observation of the Moon, planets, Sun, astrophotography
What space objects can be observed with this telescope:
The Sun - thanks to the objective solar filter included in the kit, you can safely observe sunspots, prominences during eclipses, as well as planetary transits across the Sun's disk.
The Moon with 203 mm observation optics is not limited to the Moon and the planets of the Solar System - but the Moon looks stunning through this telescope: craters, ridges, plains with all the details.
Planets - the telescope allows you to distinguish the disk and phases of Venus, Mars, cloud bands and the Great Red Spot on Jupiter, the rings and Cassini division on Saturn, as well as the disks of Uranus and Neptune.
Deep Sky Objects - the large diameter of the mirror reveals details of the distant Universe: globular star clusters decompose into individual stars, gas and planetary nebulae show internal structure, and galaxies demonstrate shape and central core. Specific objects: Galaxies - M31 (Andromeda), M51 (Whirlpool), M81/M82, M101, M104 and hundreds of others; Nebulae - M42 (Orion), M57 (Ring), M27 (Dumbbell), Crab Nebula M1, Veil Nebula NGC 6992; Globular clusters - M13 (Hercules), M92, M3 - with decomposition into individual stars; Open clusters - Pleiades, Manger M44, M35 and others; Binary stars - hundreds of pairs
Design features:
- Parabolic main mirror with a diameter of 203 mm - unlike simpler spherical mirrors, the parabolic shape completely eliminates spherical aberration and provides a sharp image across the entire field of view. The mirror is made of a special material with a low coefficient of thermal expansion H-PZ33, which minimizes shape changes during temperature changes. The quality of the optics is confirmed by the Strehl index >0.8, which meets the criterion of a diffraction-limited image and guarantees the clearest observations.
