Dark Sky

10 Replies

My father passed away last week at age 88. This essay I finished early last year is largely about him.

Dark Sky

I

On a clear, moonless night, 7,000 feet high on the Colorado Plateau, I stand in my backyard in Torrey, Utah looking at the heavens. When I shift my gaze to the ground, I realize I can see my shadow.  I move my arm about to see if a shadow is really what I am seeing. The shadow moves. The night seems inky dark. There is no artificial light anywhere.  I laugh under my breath. How could there be a shadow? The only light is coming from the summer Milky Way arcing overhead.

I don’t believe there are many people who have seen their shadow by starlight and that is a shame. In most of the country and much of the world people live in places where the skyglow caused by errant urban light makes it impossible to see the Milky Way. When I was born there were slightly fewer than 3 billion people on the planet. Now there are almost 8 billion and it shows in the sky. Satellite photos of the earth at night taken over the past decades show the expansion of light creeping like a fungus growing in a petri dish. As Joni Mitchell sang in my youth,  Don’t it always seem to go, that you don’t know what you’ve got till it’s gone. That dark sky over my head in Torrey is becoming a lost resource. Another vanishing piece of wildness.

My father has been an avid amateur astronomer and astro-photographer since the early 1980’s. The technology of telescopes was improving fast in those days, prices were starting to come down, and Dad was an early adapter of the new technologies. In 1986 when Halley’s comet was making its once every 75 year rounds past Earth, Dad invited a buddy and me to join him in the dark skies of southern Utah to take a look through his telescope. We went to Canyonlands, south of Moab. Standing outside his motorhome the night was thick with dark, the Milky Way swept overhead, and Halley’s hung in the middle of the south sky with its tail pointing up and away to the northwest. The view through the telescope did not disappoint and my buddy and I laughed as we tried and failed to keep the comet in the telescope’s crosshairs. I could see the attraction to Dad’s hobby but I was busy with a budding family and career and did not see the telescope again until 20 years later. By then Dad had reconverted in a fundamental way to religion and there was a growing distance between us. “I still have that old telescope, the orange tube C8,” he told me. “You can take it if you want to.” That was all the instruction I got, but I took him up on the offer.

Trifid Nebula, Star Factory

6 Replies

The Trifid Nebula is one of the most popular objects to be viewed and photographed by amateurs like me, but if you are in mid North America you have to be quick, it isn’t up for long. In mid-August it doesn’t get fully dark where my observatory is in Torrey, Utah until 10 PM. At that time the nebula is due south, right at the meridian, and at its highest point in the sky for the night at a low 26 degrees altitude (90 degrees is straight up). Boulder Mountain is south of Torrey and it is as dark as it gets in that direction, so it is a good place and time to photograph the object. But by 1 AM the Trifid is getting below 20 degrees altitude, getting close to the mountain and running into too much atmospheric interference near the horizon. The trick is to get some moonless, cloudless nights at these few critical hours. Mid-August worked out this year.

Deadbeat cowboys, faith, racism, dark money – and hope

From my new companion blog, The No Bull Sheet

Inter-Tribal-Logo-Brown-on-white-300x300_0316-e1459542189197Here in the West it is cowboys and Indians again. Or still. I believe the battle will soon turn against the cowboys.

Cliven Bundy and his deadbeat cowboy clan remain free, still owing the United States over $1 million in federal conviction fines and grazing fees, and still illegally trespassing their cows on desiccated public land. Trump came to Utah in December and signed away some two million acres of national monuments, the largest rollback of federal land protection in the nation’s history. Utah has lost the lucrative Outdoor Retailer convention.  As our politicians disgracefully cheer, Gallup reports that 61% of Mormons approved of Trump in 2017.

I am trying to figure out what gives. Continue reading →

Bridges in the dark

Salt Lake City | Torrey, February 2017

Last August I received a call from my 83 year old mother. “Your father wants to speak with you,” she told me. It is like that with Dad and me, not a lot of direct communication.  I told Mom I would come over the next day after dinner. When the time came I was surprised to see my wife, Kirsten, grab her purse and head for the door with me. My father has a reputation for being difficult and there are rarely volunteers to join me in seeing him. Dad is in his mid-eighties and as his oldest offspring I am to be the executor of his will. I thought he might want to talk about some details or arrangements, but when we all sat down around the table together, including Kirsten and Mom, he asked me if I wanted his observatory. I thought he was asking if I coveted his belongings, which I surely do not. But in my own advancing years I may have gained adequate wisdom so that when Kirsten kicked me under the table I ceased my objections and turned to see her silently mouth, eyebrows raised, “This is an honor.”

Black Eye Galaxy (M64)

Black Eye Galaxy (M64)

I am able to get close enough to the heavens to take photos of deep sky objects from my driveway on the Colorado Plateau because I am standing on the shoulders of giants. This subtle jewel of a galaxy first picked up it’s nick name in February 1787 when William Herschel wrote in his observing notes, “A very remarkable object, mE. [much elongated], about 12′ long, 4′ or 5′ broad, contains one lucid spot like a star with a small black arch under it, so that it gives one the idea of what is called a black eye, arising from fighting.” Continue reading →

The Whale and the Hockey Stick

“Star gazing is 50 percent vision and 50 percent imagination,” says my favorite astronomer, Chet Raymo. And maybe another 50 percent knowledge. The more you know, the more you can see. On a clear dark night in Salt Lake City, or Chicago, or Boston you can maybe see 50 stars, probably more like 25. The sky is washed out by light pollution and it is the sky most of us see if ever we look up. But we evolved under the stars of pollution free skies and on a clear dark night high on the Colorado Plateau there are still thousands of stars visible. Here the light of the Milky Way can be enough to cast a shadow. All the same, the stars we can see are a tiny fraction of the 100 billion in the galaxy. On nights like these the scene above seems to reach down to shake my sleeping natural soul awake and beg my mind to look up and see, to stand and see with imagination.

Horsehead Nebula, Torrey 2/17/2015

Horsehead Nebula, Torrey, February 17, 2015

Horsehead Nebula, Torrey, February 17, 2015

The Horsehead Nebula is part of the vast Orion Nebula complex. Just below the first star in Orion’s belt the head itself is actually a dust cloud obscuring the bright red nebula behind it. This dark molecular cloud is about 1500 light years away.

It was pretty much a perfect night for viewing in Torrey. 35 degrees and wind mostly calm. Later there seemed to be some high thin clouds but for most of the time I was out the sky was black, the Milky Way was prominent, the stars were so bright that even with no moon I could see my shadow, and Orion ruled. It was the kind of night where there are so many stars it is hard to pick out the constellations. 35 degrees is not quite cold enough that I wear insulated pants, but I do have on thick hiking boots, a puffy down parka I bought in maybe 1976 with the hood up over a ski hat, a headlamp set to red light, and finger-less fishing gloves. I still get a little chilly.

I usually set up to the east of my home in Torrey in the driveway in order to stay out of the prevailing westerly winds. The house is 2 stories high there and is an effective wind break but also gets in the way of viewing. I didn’t quite have 2 hours left to shoot after I set up before the belt wheeled behind the roof.

Rosette Nebula

Rosette Nebula, Torrey, 2/16/2015

Rosette Nebula, Torrey, 2/16/2015

This is my first deep sky object capture in a while and the first after modifying my camera to accept more red in the Ha wavelength. This cosmic rose is about 5,000 light years away near Orion in Monoceros. The red is nebula matter (hydrogen?) that is heated up by the hot stars in the center of the Rosette which formed from the same matter. I love the feedback loop here, sort of like we mortals becoming conscious. The stars form from the cosmic matter and then shine back on it, making it beautiful. The stardust that is we humans becomes conscious and looks out on the heavens, becoming the cosmos aware of itself, and is beautiful.

I tried to get this picture Sunday night but got blanked out by a strange, stuck cloud. A rare failure in the forecast by the amazing Mr. A. Danko at ClearDarkSky.com.  As part of the weird weather we are having (very weird, exactly as predicted by the global warming models), the jet stream is distorted and was blasting down with much turbulence in the upper atmosphere out of due north and created a standing lenticular cloud exactly in the way of where I needed to observe.  Monday night was much better although it did not clear up until after dusk. Good of it. In fact, Monday night was great, clear and calm, but a surprisingly cold 24 degrees. For the first time the laptop PC I was using to run the exposures quit on me at the end of the session, apparently from cold, and would not start back up. I took it inside for half an hour, fired it up, and was able to go back out and get the rest of the compensating sub frames (darks, flats and bias).

This exposure is what the hobbyists call “first light.” I recently sent my Canon Rebel T1i off to Gary Honis for his full spectrum modification which replaces the internal stock infrared filter with a special clear glass filter. Many nebula have a red wavelength called hydrogen-alpha that is filtered out by the stock camera filter. I chose the Rosette as my first object to gather some of that red I was missing. In fact, in an attempt years ago to acquire the Rosette with my stock Canon 10D, I either missed the thing altogether, something that is entirely possible, or all the red was filtered out.

I shot through the guide-scope and guided with the normal telescope, the reverse of what is normal. The guide-scope is a relatively simple and inexpensive telescope that is not meant for astrophotography. The stars are much fatter and distorted than they would be and the little blue circles around the stars are from the various color wavelengths not converging all in the same place. Still, as long as you aren’t experienced at such efforts, the end result is purty.

This exposure is 2 hours and 32 minutes comprised of 4 minute subs and using 8 each of darks, flats and bias frames.

Light on the Colorado Plateau

Kirsten in Capitol Reef NP

My wife, Kirsten Allen, and I are fortunate to live, at least part time, in Torrey, Utah in the north central part of the Colorado Plateau. Here there are both the beautiful landscape and very dark, light pollution free skies.  On the “Astrophotos” tab above you can see the deep sky object photos I have gathered taking advantage of these high, dry, dark sky conditions. I also plan to add photos I have taken during the day (mostly) of the inspiring landscape on the Plateau. I have a small start on the “Landscape” tab above.
