The mount is approximately 3.5 years old. It has an 11 5/16" RA gear and a tangent DEC with large laser engraved setting circles. It is not a GOTO mount, and cannot be modified to be one. Condition is excellent as it was only used in my backyard a few times. Weight of mount head is 135lbs. Carrying capacity is 235lbs. This is a heavy observatory class mount for large scopes. It is capable of carrying a 16" Newt. Includes tripod, three 22lb counterweights, and Takahashi polarscope. Many of the Series IIs did not have a bore in the RA for a polar scope but this one has it. I specifically requested this feature from Ed Byers. Asking $8900 plus shipping. I would prefer pickup. I am moving and do not need this mount and would rather not drag it with me.
