Celestron C8 f/10 with Metric Threads

Celestron C8 f/10 with Metric Threads

These knobs fit most Celestron C8 made in 2005 and later with black Phillips factory collimation screws; not for Fastar or EdgeHD models.

Fits: Most Celestron 8” (20 cm) f/10 SCT made in 2005 and later with black Phillips factory collimation screws that have metric threads. Includes SkyWatcher SCT and non-EdgeHD Fastar.

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

Threads: Black oxide or stainless steel

Notes:

  1. Most models with black Phillips factory collimation screws require metric knobs. A few post-2005 scopes have black Phillips collimation screws with standard threads. Here are some hints to help determine which screws your telescope has. Make sure the knob threads match the factory screw threads before installing the knobs. More information is in our Celestron technical paper.
  2. These knobs will fit the metric Fastar version only if it does not have EdgeHD optics. Scopes with EdgeHD optics require different knobs.
  3. The factory dust cover will fit normally with Bob's Knobs installed.
  4. Some telescope versions have a small plastic cover over the factory collimation screws. This cover 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.
