Astro-Physics Traveler Focuser w/Feather Touch Micro

The Traveler focuser is virtually identical to the 2.7" Focuser except that the focuser body (that houses the drawtube) has an internal thread that attaches to the tube. All other construction features and specifications are the same. The new TFOC3E-FT focuser offers critical focusing and a greaseless drawtube. Both of these are attributes that Traveler owners will find appealing.
