Bob's Knobs voor Celestron 11 inch (28 cm) F/10 SCT (metalen en carbon buis) met vlakke secundaire spiegelhouder en standaard 6-32 inch collimatieschroeven. Past NIET op Celestron CPC 1100 telescopen.

Specification:

Bob's Knobs - Celestron 11 inch (28 cm) F/10 SCT standaard:

  • Set van drie Bob's Knobs collimatieschroeven;
  • Knoppen: zwart plastic, 16 mm (5/8 inch) diameter;
  • Schroefdraad: zwart geanodiseerd aluminium legering.

Extra info:

Make sure the knob threads match the factory screw threads before installing the knobs.

The factory dust cover will fit normally with Bob's Knobs installed.

Most Celestron 11 inch (28 cm) SCTs made prior to 2006 have the flat secondary housing with standard 6-32 collimation screw threads. If your SCT has the Faster option, order  knobs for the "Trifid" Fastar secondary housing instead. Do not use knobs for the Trifid Faster secondary on the flat secondary. The screws on these knobs are too long.

The CPC 1100 SCT requires knobs with metric threads. The CPC 1100 secondary can be identified by a factory-installed plastic cap over the collimation screws. Do not use these knobs on the CPC 1100.

These knobs will also fit the Orion 11" f/10 SCT by Celestron.
