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.

Eighty-five pound pitch lap press 2014-07-06 |
||||||||||||||||||||
 | ||||||||||||||||||||
| Sometimes the pitch lap needs a little help getting back into a shape that matches the mirror. The mesh makes nice micro channels. After removing the weights and mesh we usually press again for a few minutes flatten out any pitch lifting caused by removing the mesh. We also like to keep the polishing room between 80 and 82 degrees F. |

| Tom is in the final stages of polishing. His 8 inch mirror has a slight (~200nm) turned down edge and mirror on top with a short center over center stroke will correct that quickly. |
