COLLIMATE YOUR SCHMIDT-CASSEGRAIN STYLE OR NEWTONIAN STYLE TELESCOPE WITHOUT TOOLS
Itís easy . . . just grab a Bob's Knob collimation thumbscrew and turn. You can even do it while looking through the eyepiece on most scopes. And 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.
Fits: Celestron 6Ē (15 cm) f/10 SCT versions (C6-A-XLT, C6-GT, C6-S, C6-SE, C6-SGT, others)
Knobs: Black oxide steel (black) or stainless steel (silver), 12 mm (1/2Ē) diameterThreads: Black oxide or stainless steel
Notes:The factory dust cover will usually fit properly with Bobís Knobs installed. However, some very early versions of this design have very little clearance between the factory dust cover and the secondary housing. To make room for the knobs, contact us for a free set of spacers that attach to the ring around the corrector plate to move the dust cover slightly away from the secondary assembly. These spacers are not needed for most versions of this telescope.All versions of the Celestron C6 SCT have collimation screws with metric threads.
