Collimate your Catadioptric or Newtonian reflector style telescopes without tools!
It's easy....just grab a Bob's Knob collimation thumbscrew and turn. You cane ven do it while looking through the eyepiece on most scopes. These thumbscrews are also much easier to use with gloves on. And perhaps the most importantly, you'll never drop that pesky little Allen wrench or screwdriver into the grass agin. Installation is a snap with the included intructions an you can undo the modifications any time.
