EQ-2 Orion Mount.
I used it with an ST-80 (4 lbs) and it worked very well. The manual states it can support up to 10 but that might be stretching it. You can see details on Orion's website or catalog (#9828). I will also throw in an optional accessory, the 1/4"-20 adapter needed for some scopes that have tripod mounting blocks (like the ST-80). Additional discount provided for local pickup.
Condition is very good. (Would be excellent except for two minor cosmetic shipping "dings" on one of the legs).
USPS Money Order.
