This is an Astro Sky Eliminator aluminum tripod in very-good condition. It has an aluminum head with three welded socket/clamps that accept the tubular aluminum legs.
This is a very stable / rigid tripod that works great with CG-5 (and similar) mounts. The design of this welded tripod results in much better stability than the standard folding-type telescope tripods provide.
Fixed height legs are removable by loosening large knurled aluminum knobs. Height at the mounting plate is ~ 34 inches. Astro Sky can provide legs of greater length if you want more height. The diameter of the head is 4 inches, the central hole is 2 7/16 inch in diameter. The mounting plate attaches to the head with 3 quick-connect screws.
It is good for grab-and-go use as total weight is ~14 lbs (~8 lbs for the welded head, and ~ 6 lbs for the set of legs). There are a few paint chips from typical portable use, there are no dents in the head or legs.
I am asking $165; buyer pays actual shipping (your choice)
