Copper Moon over a Copper Mine


Copper Moon over Copper Mine

A coppery Moon rises over the Santa Rita Copper Mine. 

The March 5 Full Moon was the smallest Full Moon of 2015, the “apogee” Moon. Or call it the March mini-Moon.

I captured it rising over the vast Santa Rita Mine, east of Silver City, New Mexico, my winter home this year. The Santa Rita mine is one of the oldest continuously operating mines in western North America. I shot the scene from a viewpoint west of the city, using a 135mm telephoto lens.

The image is a composite stack of two exposures taken moments apart: a long 1-second exposure for the sky and ground (but with the Moon overexposed) and a short 1/13-second exposure for the lunar disk to retain details in the disk, like the lunar mare, marking the face of the “man in the Moon.”

The March Mini-Moon

Later in the evening I used my telescope to shoot a close-up of the apogee Moon. I shot a single exposure but processed it with exaggerated vibrance, saturation and contrast to bring out the subtle colour differences in the lunar mare. You can see that some are much bluer than others, due to the higher level of titanium in the lava flows that formed these mare.

As I explained in my previous blog, in seven months the Full Moon will be at the close perigee point in the Moon’s orbit, giving us the closest Full Moon of 2015. That’s also the night of a total eclipse of the Moon. I’ll try to shoot the Full Moon with the same telescope to create a big and small Moon comparison pair.

Rising of the Snow Moon & Jupiter


Full Snow Moon over Silver City Panorama #1

Tonight the Full Moon rose paired with Jupiter, in the colourful twilight over Silver City, New Mexico.

Using The Photographer’s Ephemeris app, I scouted out the location last night for the shoot tonight, February 3.

I drove west of Silver City to a viewpoint on Boston Hill overlooking the town east to the rising Moon.

The Full Moon of February has come to be called the “Snow Moon,” appropriate for many parts of the continent now enduring record snowfalls. But here, we enjoyed summer-like temperatures and a decided lack of snow.

The Moon rose into a clear sky accompanied by Jupiter, now 4 days before its annual opposition date. At opposition we pass between the Sun and an outer planet, in this case Jupiter. This puts Jupiter opposite the Sun, so it rises as the Sun sets.

The Full Moon also always lies opposite the Sun, so tonight the Full Moon joined Jupiter in the sky.

Full Snow Moon over Silver City Panorama #2

To capture the scene I shot several panoramas, each consisting of several segments, to take in the broad sweep of the horizon. The scene above records the pink “Belt of Venus,” created by sunlight lighting the upper atmosphere to the east in the half hour or so after sunset down here on Earth.

Full Snow Moon over Silver City Panorama #3

Once the sky got darker, Jupiter stood out better, shining to the left of the Moon.

Jupiter is now also closest to Earth and brightest for 2015. It will dominate our eastern sky for the rest of the winter and early spring, eventually shining to the south as night falls in late spring.

Moon, Mercury and Venus in Conjunction


Moon, Mercury & Venus Conjunction (Jan 21, 2015)

This was the scene on Wednesday night, as the waxing Moon formed a triangle with Mercury and Venus.

Skies cleared nicely this evening, providing a beautiful view and photogenic scene of the inner planets near the waxing Moon.

On January 21 the crescent Moon appeared with Venus (at left) and Mercury (below), and with the trio above the lights of Silver City, New Mexico.

Compare this view of reality with the graphic from my blog of a few days ago, and with a similar scene a month earlier with the Moon closer to Venus but with no Mercury.

With the Moon now returning to the sky, sighting Comet Lovejoy will become more difficult.

On Thursday night, January 22, the Moon will be higher and shine near Mars.

Happy viewing!

Venus and a Silvery Moon over Silver City


Thin Moon and Venus (Dec 22, 2014)

The thin Moon and Venus hang over the lights of Silver City, New Mexico.

Tonight, December 22, the 24-hour-old crescent Moon shone a binocular field to the right of brilliant Venus. I caught both hanging in the sky over downtown Silver City, set in stunningly clear twilight.

Venus is just beginning what promises to be a spectacular evening appearance in the western sky over the next few months, as it climbs higher.

The Moon, on its shorter cycle around the sky, is emerging into the evening sky for the end-of-year holidays. Watch it wax into a quarter Moon, then to Full, over the next two weeks. Tonight, the glow of Earthshine was prominent lighting the dark side of the Moon.

I shot this from east of the city, using a 135mm telephoto on my Canon 60Da camera.

Happy holidays to all!

Stargazing under the Milky Way


Stargazing at City of Rocks State Park

What a wonderful night for stargazing under the Milky Way and amid the rock formations of southern New Mexico.

This was the scene last night, November 22, at a monthly stargazing session hosted by the City of Rocks State Park and the local Silver City Astronomy Club. You couldn’t ask for a better night … and site.

The Milky Way swept overhead, from Sagittarius setting in the west at left, to Taurus rising in the east at right. The faint glow of Zodiacal Light sweeps up from the last glow of western twilight to the left. Some faint green bands of airglow that only the camera can capture are also visible near the horizon.

Matt is doing a laser tour, following which the group convened to the beautiful roll-off roof observatory that houses a Meade 14-inch telescope. It was a fine evening indeed.

Technical notes:

The panorama, which spans about 300° (I cropped the edges a little from the full 360°) consists of 8 segments, shot at 45° spacings, with a 15mm full-frame fish-eye lens at f/2.8, for 1 minute untracked exposures for each frame at ISO 800 with the Canon 6D. I stitched the segments in PTGui software, but processed them in Adobe Camera Raw and Photoshop.

New Mexico New Moon


New Mexico New Moon (April 30, 2014)

The thin waxing crescent Moon returned to the evening sky tonight, seen here in the deepening blue of a New Mexico evening.

I’m in Silver City, New Mexico (altitude 5900 feet) for a few days and nights, checking out places to spend next winter, under clearer and warmer skies than back home … and with rarely any snow to shovel.

This was the scene tonight, on the ranch road with one of the prime property choices – astronomers check real estate locations by day and night!

The crescent Moon is lit by Earthshine as it sits amid the deep blue twilight. The stars of Taurus show up flanking the Moon, with the Hyades at left and Pleiades at right.

This image is a high-dynamic range stack of 6 exposures from 2 to 20 seconds, to capture the ground detail without blowing out the Moon. Lights from an approaching pickup truck nicely lit the trees during the final longest exposure.

For the technically minded, I stacked the images using Photoshop CC HDR Pro, then “tone-mapped” them using Adobe Camera Raw in 32 bit mode.

Sunset from Silver City, New Mexico

The sky was hazy all day and evening, from wind-blown dust common to the area. Fierce southerly winds were whipping up dust all day, which hung in the sky all evening as well.

The sunset was a golden yellow from all the dust in the air. Once it got dark the sky lacked the ideal desert transparency, muting the zodiacal light I saw last night from the Chiricahuas.

Not every night is perfect in the high desert!
