• Bob's Knobs for Meade 8" f/10 SCT with 3-Screw Secondary

  Now there is no more tools needed to make collimation adjustments to your telescope! It's easy . . . just grab a Bob's Knob and turn. You can even collimate while looking through the eyepiece on most telescopes. What's more, you'll never drop that pesky little Allen wrench or screwdriver in the grass again. Installation is a snap with included instructions, and you can undo the modification at any time.
  
  Fits: All Meade 8 inch (20 cm) f/10 SCT versions with three screws on the secondary housing (2080, LX10, LX50, LX90, LX100, LX200. It is important that you choose the correct style Bob's Knobs for your telescope. Please note the number and type of screws on your secondary housing before ordering.
  
  Since the factory dust cover contacts the secondary housing when installed, additional clearance is needed to make room for the knobs. We provide a set of spacers that attach to the inside of the dust cover to move it slightly away from the secondary assembly. You can also press the center of the cover from the inside to contour it for additional clearance. (For the LX90, the factory dust cover will fit normally with Bob's Knobs installed, without any spacers or contouring.)
  
  Later Meade 8 inch (20 cm) telescopes have six screws on the secondary housing. These scopes require different knobs. Do not use knobs for the 6-screw secondary on the 3-screw secondary. The screws on these knobs are too long.
  
  Some very early Meade 8 inch (20 cm) model 2080 telescopes have two collimation screws. Please contact us for knobs to fit this scope.
