Celestron C11 f/10 with Flat Secondary and Metric Threads

Celestron C11 f/10 with Flat Secondary and Metric Threads

Fits Celestron C11 f/10 SCT versions with flat secondary housing and black Phillips collimation screws.

Fits: Celestron 11” (28 cm) f/10 SCT versions with flat secondary housing and metric collimation screw threads (most CPC 1100).

Knobs: Black oxide steel (black) or stainless steel (silver), 12 mm (1/2”) diameter

Threads: Black oxide or stainless steel

Notes:

  1. Black Phillips factory collimation screws usually have metric threads, but some black Phillips screws have standard threads. Our hints will help you determine which screws are on your telescope. Make sure the knob threads match the factory screw threads before installing the knobs.
  2. The factory dust cover will fit normally with Bob's Knobs installed.
  3. If your telescope has a factory-installed plastic cap over the collimation screws, it must be removed and set aside when Bob's Knobs are installed. The cover is cosmetic only and will not affect operation of the scope.
