Collimate your Catadioptric or Newtonian reflector style telescopes without tools!
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. These thumbscrews are also much easier to use with gloves on. And perhaps most importantly, 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.
Part: M16-3
Fits: Meade 16" (40 cm) f/10 SCT versions with three screws on the secondary housing
Knobs: Black plastic, 19 mm (3/4") diameter
Threads: Black anodized aluminum alloy
Notes:
The factory dust cover will fit normally with Bob’s Knobs installed.
Later Meade 16” telescopes have six screws on the secondary housing. These scopes require different knobs. Do not use knobs for the 3-screw secondary on the 6-screw secondary. The screws on the 3-screw knobs are too long.
