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: C9.25fst
Fits: Celestron 9.25" (23.5 cm) f/10 SCT versions with "Trifid" Fastar secondary housing
Knobs: Black plastic, 9.5 mm (3/8") diameter
Threads: Stainless steel
Notes:
1. These knobs fit the Celestron 9.25" f/10 SCT with a Fastar secondary, which has black Phillips factory collimation screws that are recessed into the secondary housing. These versions may or may not have EdgeHD optics.
2. Knobs include a set of long spacers so they clear the rotary cover.
3. The factory dust cover will fit normally with Bob's Knobs installed.
4. The rotary secondary cover must remain open when the knobs are installed. The cover is cosmetic only and will not affect operation of the telescope.
