For Sale
Bob's Knobs for Celestron CPC-1100.
For those who like to collimate.

Personally, I never needed to collimate my CPC1100, thus these are Brand New and have never been installed.
These sell new for around $29 Plus postage in Australia.

For Sale at $17 (includes postage within Australia)

IIS Review:
You will find the Bobs Knobs easy to use in the dark as they are easy to feel rather than messing around with an allen key. Also trying to use an allen key in the dark whilst not bumping your scope around is a pain in the bum.. Bobs knobs will make you collimation very simple and painless..

Only tip with collimation is little adjustments (very small).
And when putting in the Bobs knobs, only do one know at a time so the secondary mirror stays attached. If you remove all the screws at once the Secondary may fall off onto the primary mirror..
