KineOptics Focuser HC-2 Helical Crayford 2"
Helical focusers have traditionally been the solution for achieving a low-profile Newtonian focuser. However, they've often been plagued by issues like unwanted slop in the threads and inadequate travel rates for precise focusing. While most helical focusers have a single thread, limiting the travel per turn to about 0.125 inches, even those with multiple lead threads fall short of the required rate.

Description
Why Opt for a Helical Crayford?
Helical focusers have traditionally been the solution for achieving a low-profile Newtonian focuser. However, they've often been plagued by issues like unwanted slop in the threads and inadequate travel rates for precise focusing. While most helical focusers have a single thread, limiting the travel per turn to about 0.125 inches, even those with multiple lead threads fall short of the required rate.
The Helical Crayford design overcomes these challenges by offering a fast rate, smooth operation, zero slop, and backlash-free performance in a straightforward, lightweight structure. Additionally, the HC-2 doesn't require grease, preventing the collection of debris or stiffness in cold weather.
