With an aperture that captures impressive amounts of light, Explore Scientific’s 10-inch Truss Tube Dobsonian is an ideal workhorse for deep-sky enthusiasts and a great instrument for getting highly detailed views of our planetary neighbors. The 254mm primary mirror collects more than 1,500 times as much light as the naked eye. With this light-gathering power, you can observe many bright star clusters resolved to their core, see structural elements of distant galaxies and have unforgettable experiences viewing sights ranging from the lunar terminator to a mesmerizing matrix of bright and dark nebulae.
Although its size can appear daunting, this Dobsonian telescope has a truss tube structure made from powder-coated aluminum for maximum rigidity and portability with a minimum of mass. It can be easily disassembled and transported — even in small cars — and reassembled within minutes without tools.
The telescope is easy to operate for amateur astronomers of all skill levels.
It has large altitude bearings that work with the aluminum-sandwich construction to facilitate smooth, small movements even at high magnifications. The telescope comes with a 2” dual-speed focuser with helical gearing and a 10:1 reduction that allows for fine focusing. It also includes a focuser extension for observing setups where extra back focus would be helpful. This telescope also features a flexible light baffle that limits interference from stray light sources and two radial fans in the primary mirror box that are used to accelerate temperature equilibrium. Additional accessories include a 20mm eyepiece with a 70° apparent field of view; a 1.3 MP digital eyepiece for viewing and capturing images on a Windows device; a 2X Barlow lens that doubles the magnification of the eyepiece; a Moon map marking major lunar features and spacecraft landing sites; a planisphere for locating objects in the sky based on your current latitude, longitude and time; a red dot finder and a collimation tool.
