Hi,

I am figuring an 8" F5.25 and not sure what to make of my test
pictures. I have been polishing for 5+ hours (not yet fully polished) but
want to start learning how to better test the mirror.

I have uploaded some pictures (thanks for the useful advice on how to make
these) of the mirror under test to
http://f1.pg.photos.yahoo.com/ph/jonathanlbishop/lst?.dir=/Foucault.

The surface looks pretty irregular to me, although I am guessing I have a
turned down edge and a hill in the middle. All the pictures are from the
same test, but I was having trouble holding the camera still (I see it will
be a good idea to mount the camera on the knifed edge.

I am using CO with micro facetting, but am planning to switch to red rouge
when the mirror is full polished.

I would appreciate anyones advice. Am I going really wrong here?

Thanks

Jon Bishop
