Excellent condition TeleVue Upswing head.
This TeleVue head can be bolted to the head of a
standard camera tripod that has a 1/4-20 bolt.
It turns the camera tripod into an Alt Az
mount suitable for a Pronto, TV85 or similar size scopes.
Your tripod head provides the Az motion (left-righ)
and the Upswing provides the Alt motion (up-down).
The Upswing has two adjustable friction knobs to control
the smoothness of the Alt motion, or to lock the Alt in place.
