Bob's Knobs for Vixen VMC260L Catadioptric Secondary

It’s easy . . . just grab a Bob's Knob collimation thumbscrew and turn. You can even do it while looking through the eyepiece on most scopes. And you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

Bob's Knobs - Knob 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.
