Japan Special Optics 5" SC OTA mounted on a Mizar AR-1 mount. The scope is in excellent condition, built like a tank. The mount is in excellent condition except three 1/4" holes are drilled in the top of bosses where you attach the legs. This was done by the original owner to mount on a pier. Also the casting the counterweight shaft screws into has channel lock bites on it. The Mizar is a precision "photo capable" eq mount with a DC quarts drive on the RA. Comes with the very precise optional polar scope and illuminator. Views are APO refractor like, tight round stars with a velvet black background. The only way you would know you were looking through a SCT is if you compared it side by side with an APO and you would notice a little less contrast in the JSO (due to the CO).
