Saint Petersburg Astronomy Club - Mirror Lab


We are looking for a new home
As soon as we have the new location set we will post the location and hours here.

Our 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.

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.

  Carlos Paris visitor from Ft. Myers
Carlos Paris was a visitor from the Ft. Myers area and needed help with his 6" mirror. He has
been working alone on it using an impessive home-made Foucault tester and a couple of good books.
Now he was ready to start figuring it. He finished it at the lab better than 1/9th wave during
his first visit (also 6/2).

  Steve Fredlund
Steve Fredlund started his mirror at the lab and finished it better than 1/7th wave last Saturday

  Pedro and Giovanni
Pedro and his son, Giovanni are now on the final figuring of their 10" mirror.

  Mirror Lab helps local science teacher
This 16 inch Meade Dob was donated to the local school system. George Fatolitus, center, is the
science teacher that will be using it with his students. He brought it to the Optical Lab where
we cleaned the optics, fixed some mechanical issues with the primary cell and base and then
collimated it. That's Paul McNabb at the eyepiece and Ralph Craig, right. Next Jim Hunter, who
recently finished a 16" mirror (see photo further down this page), will show Mr. Fatolitus how to
field collimate and use the scope.
