Explore Scientific 10-inch Dobsonian Telescope
Extreme portability with quick set up and tear down, the 10-inch primary mirror with 1143mm of focal length Truss Tube Dobsonian is1143mm of focal length by almost anyone and occupies a very small space in a car for easy transport. The superior components include a 2-inch two-speed rack & pinion focuser make for precise focusing. The large bearings on altitude and azimuth offer smooth pointing and stability. With the use of the optional 30mm 82 Degree Series Waterproof Eyepiece, you can visually achieve a true field of view of 2.15 degrees with a 6.6mm exit pupil for amazing ultra-wide field deep sky viewing with a limiting visual magnitude of about 13.8 in optimal viewing conditions.
This is a Generation II telescope. All updates have been performed on this telescope. No telescope type has changed the hobby quite as much as the Dobsonian Telescope. Before the popularization of John Dobson’s altazimuth 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. Large commercial telescopes could certainly do the job but were relatively expensive. 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. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in very small cars. The entire structure has been optimized for maximum stiffness with minimal weight. The combination of large altitude bearings with optimized metal structural design allows fine and smooth adjustment, even at higher magnifications.The ideal workhorse for the deep sky observers. A 254mm aperture mirror collects more than 1,500 times as much light as the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. 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. Oversize altitude (16.5-inch with adjustable clutch) and azimuth (13-inch) bearings allow for smooth operation. 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.
