Re-aluminizing the 24″ Perkin Telescope Mirror
Periodically, telescopes need to have their mirrors cleaned and coated with a new layer of shiny aluminum. Here are some photos of the removal of the 24″ mirror and preparation to ship it off for re-aluminizing on May 9th, 2013.

Astronomy professor Seth Redfield and Bruce Strickland from the Wes science machine shop move the lift into place for lowering the mirror cell.
Dave Strickland from the science machine shop aligns the lift. The mirror cell rests on metal cylinders as it is lowered from the telescope.
