Collimation Thumbscrews for the Nexstar 8SE, C8-SGT,
CPC800 and other metric Celestron 8" SCTs
This set of three thumbscrews replaces the factory collimation
screws to make adjustment easier, using no tools. Easier operation
means you will be more likely to make fine collimation adjustments
that will yield optimum viewing. No more fumbling in the dark with
a tool that could slip and scratch the corrector plate. Includes
installation instructions.
Price includes shipping in the USA!
