SKYWATCHER MAKSUTOV-NEWTONIAN

We offer knobs for the SkyWatcher MN-190 Maksutov-Newtonian primary and secondary. Select the type of knobs for your telescope from the list below.

A. Knobs for SkyWatcher MN190 Mak-Newt Primary

Part: SWMNpri
Fits: SkyWatcher MN190 Maksutov-Newtonian telescopes.

Primary collimation
  • Knobs: Black plastic, 16 mm (5/8”) diameter
  • Threads: Stainless steel
Primary Lock
  • Knobs: Red plastic, 16 mm (5/8”) diameter
  • Threads: Stainless steel
Notes:
  1. Knobs with shorter screws and spacers replace the factory Phillips collimation screws. Knobs with longer screws replace the factory set-style (grub) locking screws.
  2. Since the factory collimation and locking screws are close together, knobs must be staggered in height. The locking knobs protrude further than the collimation knobs, and they are now red in color.
  3. Protect the locking knobs from damage, and do not support the OTA using the locking knobs as feet.

B. Knobs for SkyWatcher MN190 Mak-Newt Secondary

Part: SWMNsec
Fits: SkyWatcher MN190 Maksutov-Newtonian telescopes.

Knobs: Black plastic, 13 mm (1/2”) diameter
Threads: Stainless steel

Notes:
  1. Our secondary knobs are mounted on long screws to clear the deep secondary lip.
  2. The small cover over the secondary collimation screws must be removed and set aside when Bob’s Knobs are installed. This cover is cosmetic only and does not affect operation of the scope.
