The Explore Scientific Newtonian 208mm f/3.9 with Carbon Fiber Tube; 812mm focal length; 97% EMD Coatings; No Tool Secondary Collimation; ES Finder Scope Base ONLY installed on scope and Soft Carrying Case. Cradle Rings with Handle and Vixen-Style Dovetail. Weighs 18.3 lbs. (Finder Scope and HR Coma Corrector NOT Included).

The Explore Scientific Carbon Fiber Newtonian allows this larger primary mirror, with faster aperture ratio compared to the usual 8" f/4 for deeper shots with the same exposure time. The completely redesigned secondary mirror mechanism ensures easy and optimal collimation. The large 80mm secondary mirror offers optimal field illumination. This amazing scope includes a high quality 2" focuser with 10:1 reduction; cradle rings with vixen style dovetail rail and carrying handle with option for mounting a camera or other accessory. The Newtonian Carbon Fiber scope also stands out with a lighter weight and a virtually nonexistent focus drift during long exposures.
