Bob's Knobs for Vixen VMC260L Telescopes
Bob's Knobs for Vixen VMC260L Catadioptric Secondary
Bob's Knobs sit very close to the secondary housing so the factory dust cover should fit fine. However, if the knobs contact the secondary housing before the screws reach the secondary mirror, the manufacturer can supply knobs with longer screws at no charge. If the knobs interfere with the dust cover, a shower cap can be used as a substitute cover.
