Removal of the Primary and Secondary Mirrors from the McMath Telescope.

On July 14, 2002, a group of Lowbrows met at Peach Mountain Observatory. Both the primary and secondary mirrors were removed and then transported to Chicago where the mirrors were then recoated. Due to the size (and weight) of the McMath telescope, this was a rather complex operation. The following photographs show some of the stages.

After the primary was removed, the telescope would no longer be balanced. Therefore ropes must be attached to the telescope before hand. Chris Sarnecki is seen on the right.

After the primary mirror was removed, it was placed in a box so it could be transported. The wall is painted white, the door is blue, and there is a red block near the door that supports the fire extinguisher. The mirror reflected these colors leading to the image above. Note, if you turn the image upside down, it resembles the blue, white and red of the french flag.
