Unless the scope is some sort of sentimental value, I would trash the scope and get another. But..if you want to repair it then there are many places to contact for any 2.4" (60mm) achromat lens. They are a dime a dozen. I cannot remember off-hand of any places to go, but at www.astromart.com and http://www.astronomy-mall.com/ you`ll find some places to find objective lenses. Personally I would consider getting another refractor from Orion or Telehoon, but that`s me talking. Good Luck!!
