Explore Scientific 12" Generation II Ultra-Light Truss Tube Dobsonian Telescope
This Explore Scientific 12" Generation II Ultra-Light Truss Tube Dobsonian Telescope is their very best 12" Dobsonian telescope. And, now this is a Generation II series telescope.
All updates have been performed on this telescope by Explore Scientific engineers to provide a new level of quality and performance. 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 Dobson's 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. This scope is the ideal workhorse for the deep sky observers. A 305 mm aperture mirror collects more than 1,800 times as much light as the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. Spiral structure in distant galaxies is visible, and the complex matrix of bright and dark nebulae and the sight of the terminator on the moon are an unforgettable experience.
This Explore Scientific 12" Generation II Ultra-Light Truss Tube Dobsonian Telescope includes: A 2" focuser with helical gearing and 10:1 reduction; LED Red Dot Finder, collimation assist tool; soft light baffle and two radial main mirror fan for fast temperature equilibrium. This scope is ready for the use with Explore Scientific's optional coma corrector.
