90 inch in moonlight
Here's another image from last months observing run on the 90 inch Bok Telescope. The Moon shines in the upper left and Cassiopeia is visible through the aperture of the dome just below center. This image was taken with my 10mm fisheye lens with an exposure of 30 seconds at f/2.8, ISO 400.
