Bob's Knobs for Celestron 11" SCT with Flat Secondary


Now there is no more tools needed to make collimation adjustments to your telescope! It's easy . . . just grab a Bob's Knob and turn. You can even collimate while looking through the eyepiece on most telescopes. What's more, you'll never drop that pesky little Allen wrench or screwdriver in the grass again. Installation is a snap with included instructions, and you can undo the modification at any time.

Fits: All Celestron 11 inch (28 cm) f/10 SCT versions (metal or carbon fiber tube) with flat secondary housing. It is important that you choose the correct style Bob's Knobs for your telescope. Please note the number and type of screws on your secondary housing before ordering.

Most Celestron 11 inch (28 cm) metal-tube and a few carbon fiber tube SCTs have the flat secondary housing. Some recent metal tube and most carbon tube models require knobs for the "Trifid" Fastar secondary housing. Do not use knobs for the Trifid Faster secondary on the flat secondary. The screws on these knobs are too long.
