Set of 3 knurled collimation screws for the secondary mirror of the Celestron Schmidt-Cassegrain 9.25" with Fastar system — fast, tool-free collimation

Precise collimation without a screwdriver

Bob's Knobs SCT 9.25" Fastar are knurled collimation screws specifically designed for the secondary mirror of the Celestron C9.25 with Fastar/HyperStar system. They replace the original Phillips screws, allowing collimation adjustment by hand without any tools, even in the dark during an observing session. The set includes 3 screws — the number required for correct secondary mirror collimation.

Bob's Knobs is the world's leading manufacturer of collimation screws for Schmidt-Cassegrain, Ritchey-Chrétien and Newtonian telescopes. The screws are manufactured to precise tolerances to ensure a perfect, repeatable fit, eliminating the risk of disturbing the tube during collimation with tools.
