Re: [ATM] Weird Foucault readings



The sure check is to go and put the rest of the telescope together and do
some star testing.  Remember that the glass itself reflects about 4% of the
light that hits it so you can indeed test with bare glass.  I have split the
Double Double with an uncoated 6" mirror so you have an idea of how much
light really is getting through.
