  Charlie is leaving for the clear skys of New Mexico
Charlie who is pictured
of Charlie polishing his 20inch mirror has moved to New Mexico. He'll have to contend with snow
drifts in the winter but at least he'll have some very good viewing. We'll miss you

  Ginger completes an 8 inch Mirror
Ginger Tiling has finished figuring her 8 inch mirror. It has an f/ratio of f/5.6 and was completed
on October 28th. Congratulations.

  The first ever mother-daughter team is making a 10 inch mirror
Megan sets up the mirror for testing with Robo.

  2007 Raffle Mirror is finished.
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
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.

  Completed Mirrors For October
Allen 12.5 inch annual refiguring
Tom Spano 14.25 inch Black BVC Glass
Joe Colontonio 10 inch (used a special mesh for his pitch lap)

  New Mirror Graduate Steve Kane
Congratulations to Steve Kane who completed a 10inch f/5.6 mirror that tested better than
1/5 wave.

  How to paint the inside of a tube

Paul demonstrates a device he made out of plumbing parts that allows the easy spray painting of
the inside of tubes.

  Two Mirror Graduates
Well done to Art Ross who completed a 10inch f/5 mirror and Richard Garner who
finished a 10inch f/6.2

  2005 Orange Blossom Special with John Dobson
John inspects Ralph's and Allens work. It was fun to discuss the finer points of mirror grinding
with one of the masters.
