Bob's Knobs Celestron 8" f/10 Metric Stainless Steel Knobs

These collimation knobs, made of silver stainless steel to prevent corrosion in moisture-heavy areas, from Bob's Knobs will fit most Celestron 8" (20cm) f/10 SCTs madein 2005 or later. They must have black Phillips factory collimation screw that have metric threads. This includes SkyWatcher SCT and non-EdgeHD Fastar (will not fit a Fastar with EdgeHD optics). They measure 12mm (1/2") in diameter.

Make sure that the knob threads match the factory screw threads before installing the knobs. You will not need the white spacers if the factory screw threads are 10mm long. The factory dust cover will also fit normally once the knobs have been installed.
