About
The Traveler-style 2.7-inch focuser: virtually identical to the 27FOC3E-FT but with an internal thread in the focuser body so it screws onto the Traveler's tube. It has the same greaseless drawtube, millimetre focusing scale and Feather Touch Micro 9:1 dual-speed knobs, and differs from the factory Traveler focuser only in lacking the "Traveler" engraving.
