Product Info
Manufacturer Description
Collimate your Catadioptric or Newtonian reflector style telescopes without tools!
It's easy...just grab a Bob's Knob collimation thumbscrew and turn. You can even do it while looking through the eyepiece on most scopes. These thumbscrews are also much easier to use with gloves on. And perhaps most importantly, you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.
Part: SWpri
Fits: SkyWatcher (5", 6", 8", 10") Newtonian telescopes.
Primary collimation
Knobs: Black plastic, 16 mm (5/8") diameter
Threads: Stainless steel
Primary Lock
Knobs: Black plastic, 16 mm (5/8") diameter
Threads: Stainless steel
Notes:
1. The telescope optical tube assembly will clear the Dobsonian rocker box with
primary knobs installed.
2. Knobs with shorter screws and spacers replace the factory flathead Phillips
collimation screws. Knobs with longer screws replace the factory set-style
(grub) locking screws.
3. 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.
4. Protect the locking knobs from damage, and do not support the OTA using the
locking knobs as feet.
