  1. These knobs will fit only the Celestron 8 SCT with Fastar secondary and EdgeHD optics. These telescopes are marked EDGEHD OPTICS on the corrector ring. Do not use these knobs on the non-EdgeHD Fastar secondary; the screws on these knobs are too long. Be sure to check that the thread length on our knobs matches the thread length on the factory collimation screws.
  2. The factory dust cover will fit normally with Bob s Knobs installed.
