Bobs Knobs - KNOBS FOR MEADE 8 inch f10 SCT WITH 3-SCREW SECONDARY

COLLIMATE YOUR SCHMIDT-CASSEGRAIN STYLE OR NEWTONIAN STYLE TELESCOPE WITHOUT TOOLS

It′s easy . . . just grab a Bob′s Knob and turn. You can even do it while looking
through the eyepiece on most scopes. And 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.

Fits: All Meade 8 inch (20 cm) f/10 SCT versions with three screws on the secondary housing
(2080, LX10, LX50, LX90, LX100, LX200)

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

Threads: Black anodized aluminum alloy

Note1: 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.)

Note2: 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.

Note3: Some very early Meade 8 inch (20 cm) model 2080 telescopes have two collimation
screws. Please contact us for knobs to fit this scope.

Note4: We will provide a free Allen wrench for removing the factory collimation screws
upon request. Put your request in the remarks section of your order, or send us an email with
your postal address and the model of your Meade SCT.
