Its time……

Every two years (give or take, depending on the weather), the mirror is removed from the Hale Telescope, striped off and given a new coating.

This is one of the better YouTube videos I have seen on the process.
The other place to see the action is the Palomar webcam.
I am pretty sure that Susan will be taking photos (and video I hope) of the process this time around (Scott is giving a talk in Corning (and looking at their library for information on the pouring of the two blanks) so he cant take photos this year)).
Look for a link when they get that processed.
The dome floor is closed to everyone except Palomar staff working on the mirror.
As a result, there are no docent tours this weekend, there might be one of us in the visitors gallery to answer questions…..
