Colorful sunset on Kitt Peak

This fisheye view looking south from the Steward Observatory 90 inch Bok Telescope was taken after the sun had set but while the sky was still brightly lit.  This HDR combine is of 5 images taken with my 10mm lens set to f/8 and the camera at ISO 400.  The exposures were at 1 stop intervals from 1/180 seconds to 1/10 seconds.

This view of the setting sun shows a pretty sunset - unless you're planning to use one of the large telescopes on Kitt Peak like we were - namely the Steward Observatory 90 inch Bok Telescope.  Luckily, it cleared enough later to be a productive night.  This is an HDR combine of 5 images at 1 stop intervals of exposure from 1/2000 seconds to 1/125 seconds with my 24mm lens at f/8 and my 70D set to ISO 400.
