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.
These knobs will fit all versions of the Intes 6” Maksutov-Cassegrain secondary, including the identical Orion Argonaut 150. (Please note that Intes-Micro, also known as Intes-Micro Alter, is a different manufacturer.) Price is for a complete set of knobs.
Part: MK67
Fits: Intes MK-65, MK-66, MK-67, and Orion Argonaut 150 Mak-Cass versions
Knobs: Black oxide steel, 13 mm (1/2") diameter
Threads: Black oxide steel
Notes:
- The factory dust cover will fit normally with the knobs in place.
Other Information
- Country of Manufacture: United States
