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.

 | ||||||||||||||||||||
| These are Mike's finished 10 inch and 12 inch blanks that still need to be edged and diametered. The top image shows the 3D printed pattern that they are made from. The bottom image shows that they are pre-slumped to a rough ROC. There is also an older video on Youtube that shows his entire process of making the light-weight blanks, from design and 3D printing, to plaster casting, to glass casting, to slumping and final edge finishing at https://youtu.be/hjcqsBKYUOE Mike recently posted a video on Youtube of him cutting a bunch of mirror blanks out of a thick glass tabletop. You might find it interesting. Here's the link: https://youtu.be/t0teStWs7W4 |

3D Printed Telrad Dew Shield 2021-01-04 |
||||||||||||||||||||
 | ||||||||||||||||||||
| Using an Ender 5 3D printer and a file from Thingiverse I printed a Telrad dew shield. The 16 inch Maxx has a blue focuser so I used blue plastic for the dew shield. It's a snug fit and the cutout for the Telrad dimmer could be a bit larger towards the front. It's time to tweak the model a bit. |
