Although it’s fun to photograph the Full Moon, I actually prefer photographing a thin crescent Moon, usually just a day or two after the New Moon. The thin crescent is brightly lit while the remainder is softly lit by light reflected by Earth, hence known as Earthshine. It’s also known as DaVinci Glow. As well, the Moon does not overwhelm the night sky so that stars can also be in the photograph.
During late Spring and into early Summer the crescent Moon sets in the west-northwest and this makes it a good target for shooting at Upper Lake Mary. The long and narrow lake is aligned WNW–ESE so that the Moon casts a brilliant reflection that can run the length of the lake.
I’ve shot this several times over the last few years but never tire of it. All it requires is enough of a gap in the clouds for the Moon to shine and for light winds so that the lake surface is relatively smooth.
The past few weeks have offered numerous opportunities for photographing objects in the twilight and night sky.
Above is a photograph showing the planets Venus (visible near the top of the image) and Mercury (located just below the center of the image). The glow of evening twilight on the horizon is reflected in the shallow waters of Mormon Lake.
Taken later on the same evening is a photograph showing four planets and an asteroid in a single frame. This was taken with a 24mm focal length lens to capture these solar system objects (SSO). I did this as a fun test to see if a wide-angle lens was able to capture these dim and distant SSOs. From top to bottom are the asteroid Vesta, Uranus, Venus, Neptune, and Mercury.
Zoomed-in crops (below) show the dimmer objects that are in the image above.
Before leaving that night I did a final wide-angle shot of the southeastern sky which included the constellation Orion as well as a portion of the winter Milky Way.
The following night I was out again to test my recently purchased Nikon 180mm ƒ/2.8 ED AIS manual focus lens. A few previous tests have shown that star images are pretty good at an aperture of ƒ/2.8 but much better at ƒ/4. At ƒ/2.8 there is just a hint of star spikes; at ƒ/4 they are quite prominent. This is a stacked sequence of images of the Pleiades star cluster. Image stacking was done with Starry Sky Stacker; histogram stretching was done with rnc-color-stretch.
On 18 February there was a Lunar occultation of the planet Mars. I had planned to get up early and drive to a dark location but an alarm failure meant I barely had time to get up and set up the gear on the rear deck of the house to start the sequence. Luckily, Flagstaff is a Dark Sky City and it was dark enough to get the shots. This is a sequence from just a few minutes before the Moon moved in front of Mars followed by a longer sequence after it reappeared.
Finally, Comet C/2019 Y4 (ATLAS) is in the northern sky making it an easy target—except that it is still very dim with a magnitude of about +12 at the time of this image. The still image is a stack of 49 images each 120 seconds duration at ISO 1600, 180mm, and ƒ/2.8. As noted above this lens is pretty good at ƒ/2.8 but better at ƒ/4. Because the comet is so dim I wanted the maximum light gathering ability so settled for an aperture of ƒ/2.8. Also in the image is M97 (“Owl Nebula”) and M108 (“Surfboard Galaxy”). The star Merak is part of the “Big Dipper.”
Also, there is an animation—made from the same images—showing the movement of the comet over a period of just under 2 hours.
An architect today might win an award for designing Wukoki Pueblo. The corners, angles, and lines of masonry are meticulous. From its base, the eye is drawn skyward to a height that inspires awe of this ancient craftsmanship.
The architecture blends so well with the environment that the building seems to grow out of the rock, disguising where nature’s work ends and handcrafted walls begin. Today these walls stand as a silent tribute to prehistoric people.
I have visited this site many times capturing the Milky Way above it, lightning around it, and sunsets. But I’ve never had a chance to capture the rising [nearly] full Moon until yesterday. The terrain is such that the best time of the year is December when the full Moon is farthest north in the sky. At other times of the year, nearby hills obstruct a view of the Moon until it has risen high in the sky. Even in December, the distant Tloi Eechii Cliffs rise above the horizon. But in this case, they add to the drama of the rising Moon. This was taken the day before the full Moon so that the late afternoon sun could still light up the landscape and the pueblo.
The past few days have offered several opportunities for photographing objects in the sky.
Mercury (Magnitude –0.2) and Venus (Magnitude –3.9) are very low in the evening twilight right now and a bit difficult to see with the unaided eye—but a camera can do a better job at picking out the small but bright planets. The two planets are separated by about 7°.
At the same time, Jupiter (Magnitude –2.0) and the Moon made a close pass last night with about 2.5° of separation. These, of course, were much easier to see.
And, a few days ago, the International Space Station (ISS) flew in front of the Sun as seen from my house. I didn’t even have to travel—just set up the camera in the driveway. The entire flyby takes less than one second. Warning! A proper solar filter is required. I use a filter made by Kendrick Astro Instruments.
Here are two views of the Moon rising behind Cathedral Rock in Sedona. The first image shows the Moon ~95% illuminated and was taken from the meadows in Crescent Moon Picnic Area. I like how the Moon lies behind the dark pillar located in the gap between two sunlit pillars.
The second image was taken on the following night with the Moon ~98% illuminated and was captured from Pyramid Trail, a location about twice as far away as the first image. This doubling of distance results in the Moon appearing larger relative to Cathedral Rock—a nice illusion.
