Descrizione prodotto

Purtroppo, questa descrizione non è stato tradotto in italiano, in modo da trovare a questo punto una descrizione inglese.

Bob's Knobs: Collimate your Schmidt-Cassegrain or Newton-Telescope without tools! It's easy! Just grab a Bob's Knob collimation thumbscrew and turn. You can even do it while looking through the eyepiece on most scopes. And you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

Three knobs for the Celestron 5” Schmidt-Cassegrain secondary.

Fits: Celestron 5” f/10 SCT (C5, NexStar 5SE, Omni 127) with black Phillips factory collimation screws (see the picture above). These screws have metric threads. Will not fit scopes with silver factory collimation screws.

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.
