Optec Sure-Lock Knobs for Celestron Edge HD
The Sure-Lock knobs from Optec are a new accessory that exists to replace the mirror support clutch covers on the Celestron Edge HD. These new knobs are fashioned from solid brass, and screw directly onto the mirror support clutch where the standard black conical lock nuts would. Due to the large diameter and knurled design these knobs both fit tighter and hold the primary mirror position more securely than the standard nuts would.
These knobs also use up less of your telescopes back focus than the standard knobs, leaving enough room to use accessories like the TCF-Leo Low Profile Focuser from Optec with an Edge HD OTA.
