I have used this unit a few times it gives razor sharp images,
this scope has a willaim optics 10:1 crayford focuser which in threaded onto main tube, so can be changed if desired etc.
The dew shield is retractable (slides) to make a smaller package and has a clamshell style mount
This unit has a Nema 17 stepper motor which is a bipolar 2 phase (four wire)
can be driven by any stepper style controller.
