Sunset Crater Volcano and its surroundings are illuminated by the light of a thin crescent Moon while the Milky Way and Great Rift descend - 12 July 2015. Bright blue Vega at upper right is blurred by a high, thin cloud along the right edge of the frame. The yellowish light at lower left comes from Flagstaff, 12 miles to the southwest.
Ribbons of green and red air glow paint the night sky over Bonito Lava flow at Sunset Crater National Monument, Arizona. Cassiopeia anchors the Milky Way at the center of the frame while the Andromeda Galaxy peers over the shoulder of our own galaxy just right of center. About an hour later, a rare, southerly burst of aurora illuminated this northern horizon with red and pink.
The Pleiades and Hyades crest the rim of Sunset Crater while the Milky Way hosts the bright stars of Perseus and Auriga. This image was taken along Lava Flow Trail and features the fallen snags, wild flowers, and ponderosas that decorate this stunning landscape. The image is composed of five overlapping exposures to average out noise in the sky and to provide sharp focus for both sky and foreground.
The NURO Telescope is an undergraduate research instrument administered through NAU. The view on this evening was illuminated by a nearly full moon while Ursa Minor leaps overhead. While I was making exposures, one of the researchers got in their car to leave or make a snack run and added some nice color to the scene for me.
The LONEOS Dome (Lowell Observatory Near Earth Object Survey) at Anderson Mesa no longer searches for new near-Earth objects—this work is now covered by other NEO surveys. However, the telescope is still used by the observatory to image and provide data for existing NEOs.
The Cygnus-Aquila Milky Way is dominated by the Great Rift, and the Summer Triangle, featuring the stars Vega, Altair, and Deneb (clockwise from top). This image is a stack of 3 2-minute exposures (to increase signal-to-noise ratio), and was taken just outside Sunset Crater National Monument. The camera was mounted on a SkyView Pro mount to track with the sky.
The Summer Milky way merges with evening twilight and the Flagstaff light dome as seen from just west of Sunset Crater National Monument. The view combines a stack of 3 exposures into the sky to increase signal to noise ratio.
The Summer Milky Way lingers above Lomaki Pueblo at Wupatki National Monument. The structure was built around 800 years ago and portions still stand today with windows and doorways open to the beautiful dark skies of Northern Arizona.
This is a stack of three 20-second exposures to increase signal-to-noise ratio in the sky.
