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.


Allen Maroney
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.

Lenny Remetta


Keevy McAlavy


Bruce Kazcmarik


James Lerch built our robo foucault tester and in house aluminizing chamber as well as a laser interferometry testing setup.


Ron Jones AKA the figurer is about the best mirror maker this side of the mississippi. You can see things in his 8 inch mirror that would impress a takahashi devotee.

Where the 19th Century Art of Mirror Making Meets the 21st Century
 
The Saint Petersburg Mirror Lab is a small band of dedicated mirror grinders and telescope makers living in the Tampa Bay area of Florida. We offer a mirror making class for interested persons. We strive to create the best mirrors our home brew technology can muster. This includes robotic foucault testing and laser interferometry.  
 

  Dario and Devin;'s scope gets first (day)Light

The scope focused beautifully on the 1/2 mile away target and shortly after the Moon.

components to the tube.

  It's a Wrap!
2017-04-07
The painted wrap is on the tube and it's a thing of beauty. Nice work Devin!

  The dob wrap is almost ready
2017-04-07
The transformation of the blank wrap to a masterpiece over about two hours was amazing. It will be
on the 10in dob soon.

  Devin starts painting his telescope wrap
2017-04-07
This started off as a plain sheet of plastic and a few cans of spray paint.

Ron Jones received a well deserved John Dobson award for exceptional public service in astronomy.
This included public outreach, teaching mirror grinding and telescope making and astronomy mentoring
as well as making more than a dozen telescopes. This is Ron (left) receiving his award with the
Telescope Lab's founder, Paul McNabb, Congratulations Ron!

  Rough Grinding a Honeycomb Mirror Blank
2016-11-10
Mike Davis has begun rough grinding another of his home made, honeycomb-back, light weight, mirror
blanks. Here he is using a couple of stacked barbell wights for the tool and 60 mesh silicon carbide
grit.

  Unusual Condiment Tray
2016-11-04
At the SPAC October picnic we used a 16 inch mirror as the condiment tray. It was recently started
with 60 grit and had about 80 thousandths of an inch of depth on it.

  3D Printed Focuser
2016-09-23
This is Tom Spano's 3D printed Crayford focuser. The white area was printed and it is internally
using a honeycombed design for strength.

  Paul with his finished dew heater controller
2015-09-03
Paul took a different approach and mounted the dew heater controller board from the lid of an Otter
box. This came out really nice. Great work Paul! Now all we need is a little dry air and clear
skies.
