Bob's Knobs for Takahashi TSC-225 Secondary # TSC225

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: TSC225
Fits: Takahashi TSC-225 Schmidt-Cassegrain versions

Knobs: Black plastic, 13 mm (1/2") diameter

Notes:
1. The factory dust cover will fit normally with the knobs in place.
2. The cover over the factory collimation screws must be removed and set aside when Bob's Knobs are installed. The cover is cosmetic only and will not affect operation of the scope.
