SCT Collimation Guide

[Poli_74]

Hello everyone,

I think some of you will find this guide useful. It would work for the Celestron CPC series SCT telescopes. Have tried it on my CPC 8 and it works.

Clear skies everyone.

i am not sure what everyone else does but i like to only adjust 2 of the 3 collimation screws that way i don't impact the distance from the primary to the secondary. i am not sure if this is at all relevant to SCT collimation given that the primary moves to achieve focus.
