Any opinion regarding Coulter Optics (Murnaghan?) 8"f/4 mirror?
It`s bought -95-97 I think.
Want to replace my Cave mirror f/4,5 (-73) which is awfull above 100X. (No Alika Herring signature on it;-)
I have also decided to replace the original Cave 2,14" secondary with a Newport Glass secondary (1/10 wave)

Not knowing your level of expertise,
have you had the Cave mirror tested on the bench?Coulter optics were all over the place figure wise and an f4 is a real bear to figure cleanly. It most likely won't be any better than your Cave.
