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: SMsec
Fits: Starmaster 12.5 and 14.5 secondary
Knobs: Black plastic, 16 mm (5/8") diameter
Threads: Stainless steel
Notes:
- Four knobs are included with this kit.
- These knobs will fit the AstroSystems 2.0 (used on the Starmaster 12.5) and AstroSystems 2.14 (used on the Starmaster 14.5) secondary assemblies. Both of these secondaries come from the factory with headless set screws for adjusting collimation.
- On some AstroSystems secondaries the knobs will slightly overhang the edge and enter the light path.
