About
The 3.5-inch Astro-Physics rotating focuser with Feather Touch 9:1 Micro dual-speed knobs, supplied with its endcap but without adapters. A greaseless drawtube carrying more than a dozen machined knife-edge baffles, adjustable drag screws and a thumbscrew brake keep heavy cameras focusing repeatably, and the captain's wheel collar frees the focuser to rotate to any angle before locking.
