Thanks Guy,
I will take more pics tonight and pay more attention to where I am. 
I am using a 133 lpi grating (correction to those I have told 150)
and I *assume* I was inside ROC, I like it there.
Those were my first shots ever and I was just happy to capture
anything.  I was not measuring, I was just snapping pics, I knew
there was no way I was polished yet, so why bother.  I just wanted
some pics 'for the archives'.  The shape has changed slightly since
then and looks to me like there's a hill forming in the very center
of the inner sphere, just to make things more intersting  8^)

Now, some clarification questions if you don't mind:

What do you mean?

What is this Rouge you speak of?  Is this recommended?  Do you use
it?  Will it bring peace to my life?

Like a typical decorative bulb, those ones that look twisted? 
Something like 20 or 30 watts?

Also, would you recommend I get an 85 lpi grating or am I beyond
that?
Would it be helpful on future mirrors?

Thanks,
Bill
