Milky Way and Aurora

 

 

While camping near the Colorado Wyoming Border on the night of May 27, 2017 I was treated to a spectacular Auroral display.   During the day there was some magnetic activity and Sporadic E around 9 PM.  At times a shimmering blue curtain of light could be seen as high as 40 degrees above the Northern horizon. 

This image is a 12 frame mosaic taken with a modified Canon 6D camera and 24mm Rokinon lens at f/2.  Each exposure was 15 seconds long at ISO 1600.
