Lens cleaning

  1. Dec 20, 2006 #1
    I own an Orion 120mm f\5 600mm telescope . I bought it last year from Orion . I recently noticed a cloudy patch about 2in. round on the inside of the scope on the lens , it looks like condensation to me . Ive always been careful when i bring the scope in the house fron the nights cold air and condensation does set in on the lens that i would let the scoipe worm up before i put the lens cover on . I noticed that i can unscrew the front of the scope and the the front can be taqken of lens and all still intact in its cell . Should i clean the inside of the lens this way or find another way Thanks
