Kwang, Jeff and I ventured to Wupatki and enjoyed some of the darkest most transparent skies in a long while. The Moon, Venus and Mars were dazzling, almost like light 'pollution' because of the clarity. I shot them with a 200 mm telephoto. After moonset we saw incredibly detailed winter Milky Way and of course ever-dominant Orion. I shot it with a 40 mm wide angle lens and the Canon 6D. Great night!.

Down in Sedona a photo like this would be titled "Mothership Over the Peaks"

On 10 May, the forecast of a G5 magnetic storm was promising to produce Auroras in the southern parts of the United States. I read the last time such conditions existed this far south were over 20 years ago. I had to try imaging them. I never expected to see Auroras in Arizona but went out into my driveway and waited for my eyes to dark adapt. I could see what looked like a bright skyglow to the north with faint bands of light fading in and out but having no visible color to the unaided eye. My first couple of photographic images confirmed deep reds. This image, taken on the first night, was captured with a Canon Rebel T5i, 18-55mm lens at f/3.5 and ISO 200. You can see deep red ionized gases glowing with some vertical banding. I especially like it for the meteorite in the lower right corner going up through Cygnus and pointing to the bright star Vega in Lyra. Subsequent imaging attempts at Wupatki National Park and at home over the following two nights produced images of only a faint red glow with no banding.
