90 inch and the Moon
I took this image last month when we were using the 90 inch Bok Telescope on Kitt Peak. We were waiting for the moonlit cirrus to clear out, so I set up my camera and used my LED flashlight to indirectly light up the telescope. The telescope itself is green (as you can see in some of my other photos) but the LED flashlight gives it a blue tint. This image was taken with my 10mm fisheye lens with an exposure of 30 seconds at f/2.8, ISO 400.
