We haven't gone anywhere- just working on mirrors and haven't had time to post anything new to the website.
Allen made an
href=http://www.telescopelab.com/images/early_2008/SPAC_Lab_04-2008.htm>updated image page from the last few months for your enjoyment.
From James Lerch...
There is a new place to get coatings:
href=http://www.opticalmechanics.com/reflective_coatings/about.html>Optical Mechanics They charge $10/inch with complete overcoatings. Very professional and quick turnaround time. If you don't mind going without the overcoating James will still aluminize your mirror for $5/inch but he now recommends Optical Mechanics.
From Ralph:
We just had two more mirrors finished.
Herb Conner 10" f/6
Pete S 8" f/4.5 for club scope |

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????
