Here's a 11 lb counterweight for Atlas or Sirius Mounts. Used it with my Atlas EQ-G. Complete with felt lined hole so it won't scratch the CW shaft. Orion counterweights feature a large tri-lobed lock-knob for easy grip - even while wearing gloves. Nylon-tipped lock-knob won't scratch the counterweight shaft of your EQ mount. Will ship in OE packaging with foam fit interior and shipped in a second box for protection. Some normal wear, see pictures. Orion #09863
NOT for Atlas Pro. Counterweight center bore measures 0.8" (20.32mm) in diameter. Not compatible with Atlas EQ-G Counterweight Shaft Upgrade #10144.
