Thanks for the info...I had just watched John Dobson's video where they were gringding a 16" mirror with a smaller glass and anyway they had something like 9 hours into it and weren't quite there yet ! So I was amazed that I was there with only two.

The dumb question for the moment is...what is ROC ? Radius of curve ? I did the test of reflecting sunlight and found that I am right about 64" FL, so that's about F/8, I was really shooting for F/10.

I also notice that the curve definately does not reach all the way to the edge yet, but with the MOB I should get that along with increasing the FL, correct ?

So far this is a blast, and it keeps me away from the TV, which is another plus !
