Product Details

  • These high-quality, 16 mm black plastic collimation knobs are designed to fit the 11-inch, f/10 Celestron Schmidt Cassegrain- either with metal or carbon fiber tube.

    So long as the scope in question is equipped with standard thread factory collimation screws, Bobs Knobs will fit it! (Though if it is not fitted with the factory standard Silver Phillips for the 11-inch f/10 Celestron Schmidt Cassegrain, these knobs won't fit.)  BS-C11EDG
