I wanted better fine control on my Lunt LS50THa with the feathertouch focuser, so I developed an oversized control wheel. Installation requires a 6 or 8 mm M3 grub screw, or any M3 screw at 12mm or greater. Simply remove the factory focus knob, install the new one, and tighten the screw.
These should work with any focuser that utilizes a ¼ inch D-shaft. I made three sizes - 75mm, 100mm, and 125mm (3, 4, and 5 inches - ish). The 75mm allows my scope to still fit nicely in the factory case. If you don't have a factory hard case, and clearance allows, the larger sizes will allow even finer focus control.
