Need Help On Finding Astrositall Polish

Posted by Tristan Schwartz on June 5, 2000 21:08:15 UTC

I recently purchased a pair of 6 inch, f/5 pregenerated astrositall blanks. I already have most of the grit neeed fo the grinding, bt I will need 3 micron and 1.1 micron aluminum oxide to prepolish and polish the mirrors. I can`t use cerium oxide, because it is WAY too soft to attack the hard astrositall. I need help, because I haven`t found ANY sources of these two grits. Where can I find them????
