Machined from stainless steel, this set includes three 1-lb. counterweights to balance your Meade 16" LightBridge Telescope. The stock Meade Lightbridge telescope is balanced to accommodate a small eyepiece and red dot finder. Once the user begins to add heavier eyepieces and finders, the telescope becomes very front heavy. These weights replace the push or locking screws on the mirror cell, making them a bolt-on addition.This "core" set properly balances the telescope for use with a large 2-inch eyepiece and a finder scope or Telrad.
