    Bob's Knobs for Meade 8" f/10 SCT with Four (4) Secondary Screws

    Bob's Knobs for Meade 8" f/10 SCT with Four Screw Secondary

    Itƒ???????????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. 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.

    Bob's Knobs - Knob for Meade 8 Inch f/10 SCT w/4 Factory Secondary Screws


    Note1: The factory dust cover should fit normally with Bob's Knobs installed. If your dust cover contacts the knobs, the manufacturer will 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.

    Note2: Pre-2005 Meade 8 inch (20 cm) telescopes have three screws on the secondary housing and no fourth screw on the side. The surface of the 3-screw secondary is textured, not smooth like the surface of the 4-screw secondary. The 3-screw secondary requires different knobs. Do not use knobs for the 4-screw secondary on the 3-screw secondary. The screws on the 4-screw knobs are too long.

    Note4: An Allen wrench for removing the factory collimation screws is included with your order.
