Thanks for the input folks! What is the general feeling about University Optics' mirror cell for the 13.1" Coulter Mirror? Enough Support for a mirror that size (is it 1" thick? I don't remember). When I made my 13" dob with coulter mirror, I did purchase a University Optics mirror cell, I had to do a bit of drilling to get the mirror to clamp nice in the cell, other than that I am pleased. Holds well and would do it again if I had another 13" Mark Shelton Indian Hill Middle School Tech Ed.
