My question as well. Is it a C6? That unique (to me) sliding secondary/focuser makes for some interesting collimation procedures, but it can be done--after all these years I finally feel like mine is now properly collimated. Best images I've ever had with it. I found it beneficial to use an Orion laser collimator in addition to the sight and Cheshire tubes. I don't think the C6 mirror is spherical, though. Might be wrong.
6in f/5 secondary
