Easy-to-adjust collimation mechanisms for primary and secondary mirrors require no additional tools and only one person is a unique feature of this design. Its short focal length and big aperture let you capture more light from deep-sky. The 200mm (7.9') aperture f/4 parabolic primary mirror is made from high-quality BK7 glass with enhanced aluminum coatings to provide >92 reflectivity for bright, vivid images. Oversize altitude (16.5-inch with adjustable clutch) and azimuth (13-inch) bearings allow for smooth operation. Affordable 8'-class Newtonian telescope optimized for wide-field astrophotography. Many star clusters are resolved to the core, spiral structure in distant galaxies is visible, and the complex matrix of bright and dark nebulae are an unforgettable experience. Among these objects are galaxies, globular clusters, nebulae, planets, and double stars.
Details on planets and deep sky objects will be visible even for inexperienced observers. A 254mm aperture mirror collects more than 1,500 times as much light as the naked eye. The ideal workhorse for the deep sky observers. The combination of large altitude bearings with optimized metal structural design allows fine and smooth adjustment, even at higher magnifications. The entire structure has been optimized for maximum stiffness with minimal weight. The ingenious combination of simple yet effective mechanisms with big-aperture Newtonian optics gives the Dobsonian Telescope worldwide popularity, and this telescope design typically offers the largest aperture per dollar of any telescope type.ĭisassembly of the scope without tools ensures a trouble-free transport of this great scope even in very small cars. Large commercial telescopes could certainly do the job but were relatively expensive. Before the popularization of John Dobson's alt-azimuth mount design with low center of gravity combined with a Newtonian optical assembly, the vast majority of amateur telescopes consisted of small telescopes with small mounts - which made them difficult to use for serious deep sky observations by beginners. No telescope type has changed the hobby quite as much as the Dobsonian Telescope. Please note that this product is back-ordered at Explore Scientific for an extended period of time
