I have 2 mounts for sale:
Orion EQ-2, in good working condition. Has a small ding on on of the setting circles. I bought this with an Orion 80ED but made an alt/az mount instead. The mount includes 1 counterweight and the slow motion controls. Orion 80ED and rings NOT INCLUDED.
$100 + shipping
Continental photo tripod, works fine as a photo tripod and for the ETX-90 I have mounted on it. Has a geared center column so that it can be raised up/down. The legs lock by twisting a small bit. This is an all metal tripod and the head if fairly heavy duty.
If you have any questions, feel free to contact me.
