Photographer Spends Evening on Freezing Mountain to Seize Uncommon Triple Galaxy Arch

Few folks get to see the total splendor of the Milky Way Galaxy arch — even fewer get to see the summer season and winter arms in the identical night time.

Intrepid photographer Angel Fux needed to meticulously plan her journey to the highest of Dent d’Hérens on the border of Italy and Switzerland — a summit slightly below 14,000 toes excessive close to the Matterhorn — the place she would spend the night time in temperatures approaching minus 28 levels Celsius (minus 18 levels Fahrenheit).

A double Milky Way Galaxy arch is barely seen to folks on Earth for a brief time frame every year, across the equinox.

“I first discovered the phenomenon two or three years ago, and from the moment I understood what it was, I knew I wanted to photograph it,” Fux tells PetaPixel.

“I attempted it for the first time last year from around 3,000 meters [9,800 feet], and the image received a lot of attention. I have since noticed more and more photographers attempting it, which I find genuinely exciting.”

But to get a greater photograph, Fux wanted darker skies, and that meant going greater. The Dent d’Hérens was the proper vantage level, but it surely’s a summit that even probably the most severe of climbers could not try.

“Photographers do not go there, certainly not in winter, certainly not at night,” Fux, who lives within the Alps, writes on her blog. “The gear required for astrophotography and the gear required for alpine climbing are simply incompatible in most situations.”

Fux enlisted the assistance of mountain information Richard Lehner. Together, they hatched a plan to get a helicopter raise to the highest of the mountain.

Along along with her astro-modified Nikon Z6 II, Nikkor Z 20mm f/1.8, and Benro Polaris star tracker, Fux needed to carry a sleeping bag rated for sleeping in minus 30 levels Celsius (minus 22 Fahrenheit), three-layer mountaineering boots with attachable crampons, and many heat clothes.

“We also had a rope and harness system prepared because once on the summit, I had to be connected at all times when outside the tent,” provides Fux. “Because the cornices surrounding the area made any unroped movement genuinely dangerous.”

There was a severe probability that the helicopter won’t be capable to make it up the mountain for his or her return journey. The severity of the journey made Fux hesitant about telling household and pals about her plans.

“When I showed my parents where we would be landing and spending the night, it looked like what it was — high mountaineering — and they went into a fairly stressed mode, asking why on earth I had to go to a place like that for an image,” she says.

“My answer is usually that if something moves me that deeply, and the risk is manageable, then why not pursue it?”

None of this was theater. It was the minimal required to make that night time survivable.

Fux went early to Gornergrat to acclimate and observe along with her tools. It was there she found an issue along with her digicam.

“It shot an entire hour and a half sequence and recorded nothing,” she says. “The images existed on the display but not on the card. Apparently, this is a known issue with mirrorless cameras in extreme cold, but I had never experienced it before.”

“Turns out that switching the camera off and on again helps,” she provides. “But it also means checking your images regularly to make sure you’re not missing any shots.”

Finally, on March 19, Fux and her information Richard, alongside along with his son Arnaud, flew to the summit of Dent d’Hérens.

“The moment the helicopter left, and the sound faded, something settled in,” she writes. “There was no going back until morning at best.”

Celestial Surprise

In the primary half of the night time, the winter arch appeared. In the second half, the summer season arch got here out. Out of the 2, the summer season arch is the better-known one, because it comprises the galactic heart and is densely populated.

But as Fux reviewed the pictures, she observed a 3rd arch, which didn’t belong to the Milky Way Galaxy.

“It was a faint oval arch extending in the direction opposite to the Sun, crossing the frame in a subtle but unmistakable gradient,” she says.

“This is called the Gegenschein, or counterglow, which is a diffuse brightening of the night sky caused by sunlight backscattering off interplanetary dust, directly opposite the Sun’s position.”

“It is extremely faint and rarely captured in photography. It was there, visible even in the unprocessed files, which told me immediately that the final image would contain more than I had planned for,” she provides.

The double arch had turn into the triple arch. And after safely returning to a extra smart altitude, she recovered from her efforts, and commenced to edit.

40 Hours and 300 Gigabytes

Fux says on her weblog that it was the longest time she had ever spent modifying a single picture — 40 hours.

“This time I worked entirely with FITS files, a format used in scientific astronomy that stores raw light data with a much higher bit depth and dynamic range than standard RAW files opened directly in Photoshop,” she explains.

“While Photoshop works in 16-bit, FITS files preserve the full precision of your sensor data, which means more information survives the stacking process.”

“To get there, I stacked each panorama panel in PixInsight, a professional astronomical imaging software, then stitched the FITS panoramas in AstroPixel Processor, the only software that can currently mosaic FITS frames, before returning to PixInsight for calibration and final sky processing,” she continues.

Fux says the method was gruelling: the primary 10 hours had been spent simply taking a look at numbers, histograms, calibration scripts, and features of code — no pictures

“For someone who is accustomed to seeing what they are working on, this was genuinely disorienting,” she provides.

The closing picture comprises 260 particular person exposures: 17 panels for the winter arch and 16 for the summer season arch, every panel being a stack of 4 tracked frames at 40 seconds, supplemented with further H-alpha information captured via a 12nm clip-in filter, plus 32 panorama photographs taken at nautical twilight. That’s a complete mission dimension of roughly 300 gigabytes.

It’s a novel view of the Alps and a celestial phenomenon that has by no means been captured on this actual manner earlier than. It’s additionally a view that’s quick disappearing as synthetic mild continues to pollute the skies.

“In Europe, if you want truly the darkest skies possible and an unobstructed 360-degree horizon, you have to go up — light pollution is everywhere at lower elevations,” she says.

And as for her fearful dad and mom?

“When I came back and shared the final image a few days later, their reaction completely changed,” she says. “They told me they wanted to be the first to get a large print of it. So I think it answered the question for them.”
