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: MSN8
Fits: Meade 8" (20 cm) f/4 Schmidt-Newtonian versions (usually on LXD-55 or LXD-75 mount). Will not fit the older MTS8 Schmidt-Newt.
Knobs: Black plastic, 13 mm (1/2") diameter
Threads: Stainless steel
Notes:
- These knobs will fit models with the deep dish secondary (see second photo). They will NOT fit the older models with the flat secondary.
- The factory dust cover will fit normally with Bob's Knobs installed.
- The knobs sit above the lip of the secondary housing for easy access.
- The factory collimation screw cover 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.
