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.

  Maiarotos Win at Stellafane
Steve Maiaroto and his grandson, Steve, entered their 8inch f/7 telescope in the 2019 Stellafane
optical and mechanical competitions. They won second place for optics in the 12.5" and under
category and honorable mention for mechanical. Steve originally ground his mirror at The Franklin
Institute in Philadelphia years ago and then repolished and figured his mirror at the SPAC optical
lab (see the 3-17-2019 photos below of how the mirror looked before and after). Congratulations

Here is the competation info that was attached to the telescope and the Stellafane emblem to show it
