Milky Way and a moonlit Cathedral Rock

The Milky Way rises above Cathedral Rock which is lit by the setting crescent moon.

This is similar to an image taken last year in the same location and about the same date. As with that image, this is also a composite of two images. The first was taken of Cathedral Rock as the moon was setting in the west. An exposure of 120 seconds at ISO 400 and an aperture of f/4 was used. The second image was taken a short time later after the moon had set allowing the fainter stars in the night sky to appear. This image was 5 minutes at ISO 400 and an aperture of f/4. To prevent streaking of the stars an iOptron Sky Tracker was used. The two images were then blended together.

Objects in the Night Sky 2017 — II

The past few weeks have offered a few interesting objects in the night sky + one daytime event.

Comet 41P/Tuttle–Giacobini–Kresák has been an easily photographed comet—albeit not a very bright one—in the northern sky. The first image below was taken during the interval 2103–2153 MST 15 April 2017 and is comet-centric which shows its motion amongst the stars over that period. The second image was captured during the interval 2117–2221 MST 16 April 2017.

CB Mammatus and Snow

Last week we had a cold front race across the state that was generating showers and a few thunderstorms along the leading edge of the frontal boundary. As this front passed through Flagstaff we had some thunder and lightning while it was snowing. Thundersnow is not uncommon around here and we typically see a couple occurrences each year.

Objects in the Night Sky—2017

The past week has been bountiful for photographing objects in the night sky. These objects include Mercury, Venus, Mars, the Moon, and the Zodiacal Light.

In mid-March the planet Venus was an evening object but was dropping closer to the horizon each evening. At the same time, Mercury was rising higher each day. On 18 March 2017, they were roughly side by side and presented an interesting spectacle in the evening twilight.

The following night I returned to Kachina Wetlands but later in the evening to capture the Zodiacal Light. The Zodiacal Light is a faint, roughly triangular, diffuse white glow seen in the night sky that appears to extend up from the vicinity of the Sun along the ecliptic or zodiac.

A Return to Death Valley National Park

My first visit to Death Valley National Park was in January 2014. At that time, I noted that “…I would like to return—soon—and visit many of the other wonderful locations in Death Valley National Park…” Well, it turned out “soon” was more than three years later but we finally made a return visit.

With the significant amount of rain that has occurred across the American Southwest this winter I was hopeful that there would be another wildflower “super bloom” comparable to that which occurred in 2016. But either we were too early or it just doesn’t happen two years in a row. So we were disappointed with the scarcity of wildflowers.
