Manuf. No. Bob`s Knobs mlb12pri

  • Fits: All Meade 12 inch (30 cm) f/5 Lightbridge telescopes
  • Knobs: Primary collimation: Primary locking: Secondary collimation: Black plastic, 30 mm (1-1/4 inch) diameter, 5-point fluted Black plastic, 25 mm (1 inch) diameter, knurled Black plastic, 13 mm (1/2 inch) diameter, knurled
  • Threads: Black oxide or zinc plated steel (primary adjustment); stainless steel (primary locking and secondary adjustment)
Note1: The factory dust cover will fit normally with secondary knobs installed.

Note2: Our primary knobs will clear the rocker box.

Note3: One of the primary mirror knobs may interfere with the cooling fan connector. The plug will fit properly between the knob flutes (photo), so leave this one knob stationary and collimate using the remaining knobs. If desired, you can leave the factory collimation screw that is next to the fan connector in place.

Note4: Primary mirror springs as supplied by the factory can sag from the weight of the mirror cell. Our replacement springs are stronger and provide adequate support to maintain primary mirror collimation. We recommend that the mirror locking screws remain in place for additional control.

Note5: Our low-profile azimuth lock knob will not interfere with the OTA as it is moved near the zenith.
