I just purchased the Hyperstar system for my 8" Celestron SCT. When I go to unscrew the secondary knurled ring the whole secondary housing is turning. I know that you don't want this to happen. Just wondering if anyone knows a smart way to hold that thin section of the secondary housing while unscrewing the knurled ring off.? I tried rubber gloves so not to gunk up the corrector plate with my oily fingers. I can't get the knurled ring to loosen without the whole secondary housing from loosening.
Anybody with experience with this.?
