Bob’s Knobs Celestron 9.25″ Metric Collimation Screws

Now there is no more tools needed to make collimation adjustments to your EdgeHD 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: Celestron 9.25-inch (23.5 cm) f/10 EdgeHD with factory collimation screws, with or without Fastar compatible secondary. 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. Some telescope versions have a small plastic cover over the factory collimation screws. This cover must be removed and set aside when Bob’s Knobs are installed. The cover is cosmetic only and will not affect operation of the scope. Bob’s Knobs Product Number: C925FST
