Here is something you don't see very often. The lights on inside the dome of the Hale Telescope at night.
I have always liked this shot because of the mix between moonlight (illuminating the dome), starlight (can you spot Orion and Taurus?) and the interior lights. It is the only photo that I have taken ever to appear on the cover of a phone book
This picture was taken in the fall of 2004 during some engineering time. The lights were on while some new equipment was being prepared for use later that night.
I have uploaded this photo at a higher resolution than I normally do. Click on the image to see it in a much larger size.
