Collimation Thumbscrews for NexStar8-GPS,
C8, C8 Deluxe Fastar and U-2000
This set of three thumbscrews replaces the phillips type
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.
If your existing secondary holder is textured (as shown here)
and has "8" in the center, these #CSN8 are the correct
Not for 8SE! If the secondary holder is less textured and has
"8/203" in the center, Metric collimation screws are here!
Prices include shipping in the USA!
