The Explore Scientific 16" Truss Tube Dobsonian f/4.5 is a premium large-aperture reflector designed for serious deep-sky observation and lunar-planetary viewing. Its 406mm parabolic primary mirror features a highly reflective coating that corrects spherical aberration across the entire field of view, while the lightweight truss tube design enables surprising portability for a 16-inch telescope. Equipped with a dual-speed 2-inch helical focuser (10:1 reduction), LED red-dot finder, collimation assist tool, soft light baffle, and rear-mounted cooling fans, this Dobsonian delivers exceptional light-gathering power with convenient accessories for fast thermal equilibration and precise focusing at high magnifications.
