This 16” Explore Scientific telescope is an ideal workhorse for celestial observers who want to delve deep into the Universe. A 406 mm mirror collects more than 2,400 times as much light as the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. Thrill to the sight of the elusive Horsehead or North American Nebula, and see faint structure in galaxies, planetary nebulae, and more with this powerful 16-inch Dobsonian telescope! Bright wide views at low power can capture more than one deep-sky object in the field!

Disassembly of this 16-inch Dobsonian telescope without tools ensures a trouble-free transport of this large aperture telescope, even in smaller cars. The entire structure of the Explore Scientific Truss Tube Dobsonian has been optimized for maximum stiffness with minimal weight. The combination of high altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications.

This 16" Explore Scientific telescope includes a 2" dual-speed focuser with helical gearing and 10:1 reduction, an LED Red Dot Finder, a collimation assist tool (see extra images for a view of the collimation assist tool in action), a soft light baffle to keep stray light from dampening contrast at the eyepiece, and two radial main mirror fans for fast temperature equilibrium. An optional coma corrector is available separately.

There is a 3/8th's pre-drilled hole along the side of the fans to allow for the installation of the Truss Tube Dob Counterweight Set, sold separately, should you require some extra balancing support for your Explore Scientific telescope.
