Bob's Knobs voor Celestron 8 inch (20 cm) F/10 SCT bouwjaar 2005 en later met metrische zwarte Philips collimatieschroeven (sommige CPC 800 modellen) .
Bob's Knobs - Celestron 8 inch (20 cm) F/10 SCT metrisch:
- Set van drie Bob's Knobs collimatieschroeven;
- Knoppen: zwart staal, 12 mm (1/2 inch) diameter;
- Schroefdraad: zwart staal.
These knobs will fit only 2005 and later C8 models that have black Phillips factory collimation screws. All C8 models made prior to 2005 and all post-2005 models with silver factory collimation screws require C8 standard knobs. Check that our screw threads match the factory screw threads before installing.
The factory dust cover will fit normally with Bob's Knobs installed.
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.
