I have a big adjustable field tripod that has served me well. This is a good sturdy tripod that can carry scopes up to 10” SCT’s, etc.
It has: 2” diameter chrome/steel legs (adjustable height), 6.5” diameter cast aluminum head with a cast aluminum leg brace/plate. There is a central (removable) ½-13 mounting stud, as well as 6 threaded holes (5/16-18). Weight is ~20 lbs – big enough to be stable, light enough to be portable.
I am asking $175; buyer pays actual shipping (probably $15-20 UPS ground).
