The 90 inch Bok Telescope

I've been on Kitt Peak the whole year (ok, tonight's the 4th of 4 nights...).  The last 2 nights I have been observing with the Steward Observatories 90 inch Bok telescope.  Tonight was not a very useful night as thin cirrus was present even at the start and it only got thicker as the night progressed.  Finally, we paused our observing and I took the opportunity to take some images of the telescope still pointed on the sky at our last target.  This image was taken with my 10mm f/2.8 fisheye on my Canon 70D with an exposure of 30 seconds at f/5.6, ISO 6400.  I painted the scene with my LED flashlight.
