Feather Touch® 2.0″ Diameter Rack/Pinion Dual Speed, 1.5″ Draw Tube Travel, Brake, and Compression Ring. The focuser utilizes the pinion assembly of our 3.0″ focuser for greater lifting capacity. For ease of rotatability the tube adapters will use 3 thumb screws instead of set screws. The motor needed for this focuser is the HSM30, MSM30 or the PDMS-2.5/3.0″ Feather Touch®.
The attached photo shows the styling of the tube adapter which is sold separately.
