Off, Again, to Mt. Wilson July 17, 2015....

I'm off to Mt. Wilson, this time, for an evening of tours tour and
viewing through the 100" -- July 17, 2015. By far, the largest telescope
I've had the pleasure of looking through.

The 100" looks like this photo, these days. A nice "heavenly blue"!!

During observing hours, red light is illuminates the dome.
