I made an expedition to northern Arizona in November of
1998. It was partly to find out what is involved in transporting photo and
telescope guiding equipment to other parts of the world. Although cumbersome (I
shipped a 90 lb crate ahead to be available when I arrived), it worked.
On the first night I found a remote site in the high desert.
The map showed what looked like paved roads to a fishing lake. Evidently the
map notations are different in Arizona; at least there were ruts where earlier
vehicles had found their way.
The lake was remarkably calm and I marvelled at the darkness
of the sky as I watched Orion rise in the east. I could hear wildlife including
coyotes, owls, and yes, ducks. But they were far away and the water remained
like a mirror. The sky glow here is not from aurora, but instead from distant
Flagstaff, a city with an ordinance to use sodium vapor street lighting. The
color is strongly yellow, but easily filtered and removed by the astronomical
observatories that are hosted by the town. My film however captures all of it.
Although Orion is spread out into an unrecognizable form, he
can be identified by the bright orange star, Betelgeuse on the left, and bright
blue star Rigel on the right. The triad of belt stars makes a catscratch-like
trail, and you may notice a distinctly red star that is even more obviously red
in its reflection. This is the famous Orion nebula, a glowing region of gas and
dust where new stars are being born.
There is a progression of techniques in taking pictures of
the night sky. The simplest is to place your camera on a tripod and open the
shutter for a while. The stars form streaks on the film as the Earth rotates
under them, creating a startrail image. As I considered what I would need to
take more advanced astrophotos, I found that there is plenty to learn and much
opportunity for pleasing compositions even with this simple method.
I pondered how to capture that feeling I once shared with a
friend seeing the stars from zenith to horizon, then continuing beneath us as
we looked out over their reflections in an alpine lake. This became the
inspiration for my quest of the ultimate startrail picture: a full semicircle
of startrails reflected in the calm waters of a lake. I have not achieved this
goal, but the pictures in this series are some of the rewards along the way.
Kinnikinnik is the closest I came to making my target image!
The conditions were perfect: a clear dark sky, no aurora, a calm lake with no
creatures disturbing it, but my timing is off. This is my first and only time
at this site and I arrived late after a day of traveling. I was unprepared to
last the night, and after a few one and two hour trial exposures, I succumbed
to the cold and returned to my distant hotel room to recharge. I never made it
Although not successful that year, I am looking forward to
more adventures in future years. In a way, I hope I never quite find full
success in this project!
To find truly dark skies, go north. My friend John Walsh, an avid backpacker, headed to the northernmost part of our state for a fall weekend adventure. I convinced him to take my camera and film, explained how to attach chemical handwarmers to the lens to keep it from fogging over, and asked him to open the shutter for six hours when he got there. Among his other nice photos of aurora and bright stars, is this beautiful picture across a gently flowing stream, reflecting the night sky and the northern lights.
This night had brought together nearly all the elements for
my target picture: a lake far away from
city lights and radio towers, one with no cabins or roads on the north while I
had access from the south, a long night to contain a long exposure without the
lake being already frozen, a stagnant high pressure center stalling the winds
and keeping the lake surface at a mirror finish. And my schedule had allowed me to take a
night away to make the shot! All these
prerequisites had been met.
I set up my equipment and busied myself with other
activities while the camera recorded the motion of the sky. A loud KERSPLASH startled me. Who would be throwing boulders into the lake
in the middle of the night? I peered out
onto the lake to see dark shadows swimming back and forth directly in front of
my camera. Each traversal left a wake
breaking up the reflected starlight.
Occasionally a shadow would suddenly turn over end and dive, slapping
its tail onto the water surface to make the boulder-throwing sound.
I cursed the beavers.
They filled the night with constant gnawing sounds as they busied
themselves around me. About halfway
through the night I was startled again, this time by the sound of a tree
crashing to the forest floor next to me.
One more hazard to add to my list.
The picture I obtained was almost perfect, accented by the
glow of the northern lights, and the intermittent breaks in the reflected
trails as the beavers swam across the view, oblivious to my intent.
Think about lying on your back as a child watching clouds drifting past. This is the nighttime equivalent. The stars etch a trail on the film as they follow their course through the night. The different temperatures of stars show as different colors, the cooler stars glow a warm orange, the hottest stars are a bright blue.
While camping trips make great venues for photographing the
sky, sometimes it is difficult to get a full view of it. But here is an opening
in the canopy, the lodgepole pines framing the pole star. The camera was aimed
at Polaris, and the shutter opened for an hour. The flickering campfires and
lamps illuminated the boughs of the trees.
A startrail picture like this is a powerful illustration of
the Earth’s motion. The pole star shows almost no motion. The others show
longer arcs the further away, but all of them make an equal arc: a one-hour
exposure cuts 1/24th of a full circle.
I am at the end of my designated time for this
expedition. I must now return from
whence I came, to a civilization density that can host a technical conference,
and will also develop the latent images captured on my film from this remote
As I reflect on the past few days I realize that there are
more things that I would like to do. I
never did get to the Goulding Museum, or to the trading post near there (which
I was told by the traveler couple was closed on the weekend).
On this day, I manage to travel to Four Corners, a
geographic location that is only meaningful to cartographers marking the
human-made political bounds of different territories. There is certainly no physical or geographic
rartionale behind it, as the view from the constructed concrete platform
holding the National Geologic Survey brass benchmark is the same in all
It had been a late night with an unexpected adrenaline rush at the end, and so it was predictable that after finally settling down, I would sleep well into the next morning. After showering and shaving, the next order of business was to upload the photos from my digital camera and assess my success at the guided exposures from last night.
Unfortunately, my laptop did not recognize any of the raw
(.CR2) image files from the camera’s memory card! This was a setback since I was planning to
copy the images to the computer, and then reuse the memory card (I only had two
of them and the second was filling rapidly).
