Bob's Knobs for Meade 8" f/6.3 Wide Field Telescopes
Bob's Knobs for Meade 8" f/6.3 SCT
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.
Note2: An Allen wrench for removing the factory collimation screws is included with your order.
