- The factory dust cover will fit normally with Bob's Knobs installed.
- Pre-2005 Meade 10” telescopes have three screws on the secondary housing. The 3-screw secondary requires different knobs. Do not use knobs for the 6-screw secondary on the 3-screw secondary. The screws on the 6-screw knobs are too long.
- An Allen wrench for removing the factory collimation screws is included with your order.
