Notes:
  1. These telescopes can have factory collimation screws with either standard or metric threads. Silver Phillips collimation screws are standard thread. Some black Phillips collimation screws are also standard thread. See our hints for more information. If you discover your knobs have the wrong threads, you may return your knobs for exchange at no additional cost. Alternatively, you can order knobs with both standard and metric thread screws and return the unused set for a full refund.
  2. The factory dust cover will fit normally with Bob’s Knobs installed.
  3. The rotary secondary cover must remain open when the knobs are installed. The cover is cosmetic only and will not affect operation of the telescope.
