Description
The model of the Bresser Messier 8" Dobson telescope with a sononic filter (4716420) has been updated to the class of Diffraction limited optics with a Strehl number greater than 0.8, which means that this telescope practically reduces aberrations. The Bresser Messier 8" telescope Dobson is the ideal Newtonian reflector for visual monitoring of Deep Sky objects. An eight-inch mirror head and a stable alt-azimuth Dobsonian mount ensure excellent transmission of images of distant stars, nebulae, and comets. This telescope can be used both by sprouting cobs and by “stuck” cobs. The most commonly used component of a telescope is the focuser, and the importance of the reliability of this component is difficult to overestimate. One of the rest of the company's improvements for this telescope is the new Hexafoc focuser with an internal diameter of 2.5". Therefore, this solution avoided the possible vignette (cropping) of the image when working with wide-field two-inch eyepieces. In addition, attention was paid to the smoothness of operation and the stability of the focusing system itself. The head mirror of the Bresser Messier 8" Dobson telescope has a parabolic shape and is made of borosilicate. glass (H-PZ33), which is characterized by low coefficient of thermal expansion, high mechanical hardness, and miraculous chemical stability, which is why this telescope is classified as Diffraction limited optics. The lightweight alt-azimuth mounting made from laminated chipboard is equipped with steel roller bearings for azimuth orientation and Teflon bearings for elevation orientation. The installation uses steel fittings, so it is easy to assemble/disassemble and has a significant service life. The telescope tube is fixed on the mounting with the help of fastening rings, however, it can be easily removed and rearranged on another, for example, equatorial mounting for the ease of use of the astronomical clamp. The flagship line of Messier telescopes from the German Bresser telescope is distinguished by high folding capacity, precision of the supply of optical elements and high-quality components materials. There are no compromises between price and price. All components, parts, and mirrors of the telescope are made with precision precision, which provides the best optical and operational characteristics in its class. Bresser Messier telescopes are highly rated by experienced astronomy enthusiasts.
