Starlight Posi Drive Motor System for F/T and AP Focusers - Fine Focus

A model of the Starlight Posi Drive Motor System meant to be used with 3.5" Focusers. The Posi Drive Motor System has a lift capacity in excess of 56 pounds, attaching to the pinion shaft rather than the assembly- eliminating the danger of slip and ensuring precise repeatability with heavier payloads. Meanwhile, the PDMS has 2.3 microns per step (.00009") which is 11,400 steps per inch. The PDMS-FT motor comes standard with an over-ride to allow for manually focusing with the Fine focus knob. What is more, the PDMS motor has the thermistor built onto the motor circuit board for temperature compensation.
