  1. The factory dust cover may interfere with Bob’s Knobs. A shower cap can be used as a substitute cover.
  2. These knobs sit very close to the secondary housing. However, if the knobs contact the secondary housing before the screws reach the secondary mirror, Bob's Knobs can supply knobs with longer screws at no charge. Contact Khan Scope Centre if you need special order knobs.
  3. These knobs will not fit the VMC200L.
