Polishing & Figuring

Plenty of work going on with Polishing & Figuring, as students work to complete their mirrors.

	2010-11 Stellafane Mirror Class Session 6 held on 2011-Mar-05 Polishing & Figuring Well, you can't figure a mirror by staring at it, but we tried! Rick, Dave & Michael stare at the surface figure printout from Michael's mirror, while Ken seems to be looking off in the distance, perhaps looking for inspiration on what stroke to use :-)

Testing

Testing is the key to making a good mirror; you need to know what your surface looks like so you can zero in on a good figure.
