Bob's Knobs Collimation Knobs for Skywatcher 190mm Mak-Newtonian Secondary - MN190SEC


Bob's Knobs Skywatcher 190mm Mak Newtonian
Collimation Knobs for the Secondary

This set of Bob's Knobs secondary collimation knobs is designed for the SkyWatcher MN190 Maksutov-Newtonian telescope. The knobs are made from a black plastic that is 13 mm (1/2") in diameter. The threads are stainless steel.

  • To clear the deep secondary lip, Bob's Knobs secondary knobs are mounted on long screws
  • When the knobs are installed, the secondary collimation screws must be removed and set aside. No worries though, the cover is cosmetic only and will not affect the functionality of the scope
