Since we had the eclipse yesterday - it reminded me of this photo-set I took.
Several years back I did some work at an interesting "Natural Observatory" jobsite designed by James Turrell. Basically, it is an installation built inside a extinct volcano that uses Earth's alignment to view certain celestial events / objects. The elliptical opening (which is a perfect circle in the viewing chamber due to the angle of the keyhole shaped tunnel) is the "window" and there is a several hundred yard perfectly aligned keyhole shaped tunnel and a precision optic ground by U of A that projects the cosmos onto a multi-ton block of polished marble in the "viewing room" underground. The staircase is cast bronze. I snapped a few quick pics there with the camera I had at the time (Sony Nex 3 & kit lens.)
