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.
