NEW: Byers Stepper motor controller w/ two stepper motors, never used, Byers originally sold these for about $2000 with the motors, asking $995 plus shipping.
This unit is sidereal with any drive that takes 1 RPM motors, which is what is included (1 RPM stepper motors).
Tested and verified to be working correctly, can field slew as well. Byers claims the controller port to compatible with most CDD units such as the Santa Barbara units for auto guiding.
Please note: There is some "browning" (discoloration) of the grey plastic on the left side of the case from storage.
