| The Galileo G-80DB transforms the easy to use and affordable  Dobsonian telescope design into a portable, light-weight system you can take  anywhere. The G-80DB features a compact matte black finish base and the overall  size of the G-80DB, standing just over 1ft. tall and with a 1ft. diameter base,  makes it perfect for almost any table or stand.  The 80MM Primary  mirror delivers the light gathering ability of a full size Reflector telescope,  but is very portable.The Galileo G-80DB optical tube assembly features a 500mm  focal length and is finished in a matching matte black granite finish. The  Primary mirror is an 80mm heavy duty mirror cell with push / pull collimation  screws. The primary mirror is aluminized with Silicon Monoxide Quartz overcoat  providing 92% reflectivity and a resolving power of .86 arc seconds. The  optical tube assembly is diffraction limited at λ4 (1/4 wave in Sodium light). The  focuser is a 1¼″ format helical rack and pinion focuser. The finderscope is  Galileo's Mars' Eye electronic Finderscope which helps by getting the observer  behind the telescope without losing the surrounding field of view when  targeting objects. Included with the G-80DB are a 1¼″ 20mm eyepiece and a 1¼″ 6mm  eyepiece with an apparent field of view of 52.
