FYI, Eric finished his mirror today. It tested 1/6th wave or better on all axes tested. This
frees up a table if anyone wanted to work on a mirror???? RC

Charile.

The 2007 OBS Rafflescope Mirror was completed. On robo foucault it tested out to 1/15th wave. Of
course we now have to build the scope to hold it.

  Hazel Gehlsen newest Mirror Lab graduate
2006-06-03
Congratulations to Hazel Gehlsen who completed an 8 inch f/6 mirror that tested better
than 1/9 wave! Hazel is also the first woman to complete a mirror in the lab. She did such a
good job on her 8 inch we'd thought we'd get her to help out on an 18 inch as well.

Allen 12.5 inch annual refiguring
Tom Spano 14.25 inch Black BVC Glass
