Founder

Paul McNabb founded the mirror lab in 1997 in order to create the best amateur telecopes possible. Inch for inch our mirrors surpass store bought or commercial grade scopes.

Lab Members

Ralph Craig is a lab instructor and has made mirrors from 6 inches to his recently completed 16 inch f5 mirror.

has completed three mirrors in the lab between 8 and 18 inches. Allen is also buiding a second robo foucault tester based on James design.


Mike Davis
casts his own mirror blanks.


Irv Nadelhaft


Charlie Mullen ground the mirrors for two years worth of rafflescopes but now has moved on the clear skys of New Mexico.

  New 16 and 18 inchers Debut at OBS 2010
2010-02-21
Ralph Craig and his 16inch f/5 Dob at the 2010 Orange Blossom Special (OBS) Star Party on 2-10-2010.
This was first light for this telescope, which was completed about a day before the star party
began. Ralph made the 16" mirror for this telescope at the OBS Optical Lab. Allen Maroney and
his 18inch f/4.89 dob during first light on 2-6-2010. Allen made the 18" mirror for this
telescope at the SPAC Optical Lab.

  We're still Here. Photos for 2009
2009-04-12
Lynn, Irv and Allen are all finishing up telescope projects. href=http://www.telescopelab.com/images/OpticalLab_2009/SPAC_Lab_2009a.htm>Here are some recent
pictures.

  Early 2008 Lab Update
2008-04-30
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

Jim Hunter finished his 12.5" mirror last weekend. I think it is a little under f/6. Came in at
1/8 wave. RC

  Joe starts work on his second mirror
2007-04-29
Joe is starting work on his second mirror using a fused quartz 14 inch blank. Here is a picture of
his first telescope made at the lab. It's a 10 inch f/6.

  Eric Finishes his second mirror a 12.5 inch
2007-04-02
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

  Website Update
2007-02-25
The Mirror Lab website has been updated. There are still lots of things to be done with the website
but the majority of pages have been updated. We've added a new feature href=index.php?page=sagitta>a sagitta to focal length calculator.
