I have the Edmund Astroscan Tripod #V39-257 for use with your standard base, Yes that's what the 1/4" thread is for, plus the Astroscan Tripod Bracket #V72-314 for use on standard photo tripods both for $55.00 shipped to you. Both items are new never used. I just checked the threads on each item to make sure they were good. In case you are wondering the Tripod sells for $69.95 and the bracket for $49.95 from Edmund. Save over 50%. I will post picture shortly.
Thanks for Looking
