Milky Way over Yellowstone National Park Old Faithful geyser Night Sky Landscape Astrophotography Canon 60Da

Yellowstone National Park is famous for its geysers and wildlife, but after sunset it becomes one of the most remarkable dark-sky locations in the United States. On this clear October night, I photographed the Milky Way rising above Old Faithful Geyser using a Canon 60Da. The mixture of starlight, geothermal steam, and the silence of the geyser basin created an unforgettable nightscape.


The green color near the horizon is natural airglow — a faint emission from the upper atmosphere — not light from the geyser. The combination of airglow, steam, and the bright Milky Way core created an almost surreal view of Yellowstone’s night sky.

A Missing Native American Legend

There are countless legends about the Milky Way across world cultures. Every civilization described it through metaphors, animals, and stories that reflected their own worldview. Since Yellowstone was sacred land for many Native American tribes — and since many tribal stories were not shared with outsiders — very few Yellowstone-specific Milky Way legends survive today.

Last year my daughter was learning about Native American traditions, and I asked her to create a “missing” Yellowstone legend — one that connects Old Faithful, nature, and the Milky Way. 
Here is the legend she wrote:
      
                                         The geyser, crow, corn, and the Milky Way

During fall the Native Americans were harvesting corn. One day a crow came, it wanted back some of the corn it gave to the Native Americans. It kept stealing the corn until the village made noise shakers and scared the crow away. While the crow was flying away holding corn in its beak, a geyser erupted and the corn kernels flew out of the crow’s beak. The crow chased it into the sky. From this day forward the corn kernels became the stars, and the dust has become the Milky Way.

Pretty much it is very close to what you see on picture above.

Interesting Scientific Note

Recently astronomers discovered enormous “galactic geysers” near the center of the Milky Way — giant outflows of gas rising thousands of light-years above the galactic core. In a way, this science echoes the legend: geyser-like eruptions shaping the appearance of our galaxy. Different level of understanding, same beautiful imagery.



There is supervolcano night sky video on youtube. A supereruption of Yellowstone volcano will affect all word. Nobody knows when it happens. Geyser eruptions show that the Yellowstone giant volcano is still active, it just sleeping under wide and starry sky.

Halloween Astrophotography - Night, New Moon, Street-Lamp and Spider Web

This photo was not taken on Halloween, but the moment I reviewed it the scene naturally reminded me of a classic Halloween mood — a new moon behind thin clouds, a glowing street lamp, and a spider resting on its web. I captured this atmospheric moment near Yellowstone Lake Hotel while testing a new lens. The weather was not suitable for deep-sky photography, but sometimes small details create their own story.

Just after sunset, only the moon was visible in the sky while thin clouds drifted across it. The warm light of the street lamp illuminated the spider on its delicate web, giving the scene an unexpected, almost cinematic feel.

Camera Settings

  • Camera: Canon 60Da
  • Lens: Canon  EF 200mm f/2.8 L II USM Telephoto Lens
  • Exposure: 1/400 sec
  • Aperture: f/2.8
  • ISO: 3200
  • Notes: Fast shutter to preserve natural brightness of moon and lamp

About the Lens

For this image I was testing my Canon EF 200mm f/2.8L II USM, a telephoto prime lens well known for its excellent sharpness and simple optical design. Unlike zoom lenses with many internal elements, a prime lens typically offers better contrast and fewer distortions — especially useful in astrophotography where precision matters. Since most night-sky photography does not require zoom, this lens is a great match for capturing small illuminated subjects or atmospheric details.

About This Photo

Even though this was not a Halloween night, the elements came together — moonlight, thin clouds, spider, and lamp — to create a scene with a Halloween-like character. This small moment became a unique part of my Yellowstone astrophotography series.

On this quiet night in Grand Teton, I noticed an unusual dark cloud moving slowly across the Milky Way. It wasn’t a deep-space shadow, but a real Earth cloud, illuminated only by starlight.
Under urban skies near New York, clouds glow from light pollution and never appear dark — but here, without moonlight and artificial glow, the same cloud became an inky silhouette against the stars.
I waited until it drifted over the brightest part of the Milky Way, creating the illusion of a UFO-shaped shadow floating across the galaxy. Camera Canon 60Da; Wide Angle Lens EF16-35mm f/2.8L II USM; Exposure 30.0 sec; f/2.8; ISO 4000

In light-polluted areas, clouds always appear bright because they reflect city lights. But under a real dark sky, clouds can look darker than the surrounding sky — even black — because there’s no artificial light to illuminate them. When such a cloud passes over the Milky Way, it briefly hides millions of stars, forming a dramatic silhouette that looks almost supernatural.

Yellowstone Night Landscape – Geyser Eruption (Canon 60Da Astrophotography)

During this night in Yellowstone I had only a short window of clear sky, so I photographed Old Faithful during one of its nighttime eruptions. In some images (Image 1, Image 2, and Image 7) the geyser is captured at the peak of its activity, when the steam column rises very high and fills much of the frame even with a wide-angle lens. In the other photos the geyser shows its normal continuous steam, which is still bright and impressive at night but not as large as during the peak. After the strongest burst, the dew and moisture were so intense that I had to warm the lens before continuing photography.

All images were taken with the Canon 60Da and the Canon EF 16–35mm f/2.8L II USM wide-angle lens — an excellent combination for night landscapes and astrophotography thanks to its bright aperture and clean optical design.

This long-exposure black-and-white image shows how differently a camera sees the night compared to human eyes. A camera can expose for 30 seconds or more, while our eyes collect light for only a fraction of a second. The bright green airglow seen in photos appears as white or grayish clouds to the naked eye.

Reflection of Ursa Major (Big Dipper) Grand Teton Nightscape Astrophotography Canon 60Da

Night sky at Grand Teton is so dark that you can easily see reflections of the stars. Jackson Lake, Colter Bay, Grand Teton National Park – reflection of the Big Dipper (Ursa Major constellation). You can see green airglow near the horizon and “star paths” — lengthened reflections of stars caused by slightly agitated water.

As simple as possible.

Grand Teton Astrophotography Wyoming National Park

Two interesting effect are visible on this photo. If sky stars don't have big trails, reflections of stars have pretty much visible "star roads". Actually every star reflection has its own "star path" like Moon reflection has moonpath. When stars more close to horizon than "star path" of reflection is longer. Reflection stars near horizon also looks brighter because of near horizon light from starts more parallel to water surface and has bigger reflectivity.

Big Dipper (Ursa Major constellation) over Old Faithful geyser Yellowstone Wyoming Astrophotography

During my nights in Yellowstone National Park I photographed one of the most familiar northern-sky constellations — the Big Dipper, the famous asterism of Ursa Major — rising above the famous Old Faithful geyser. Even without a major eruption, the drifting steam created a beautiful and dramatic foreground for the stars.

These images were captured with the Canon 60Da, a camera designed specifically for astrophotography, paired with a Canon EF 16–35mm f/2.8L II USM wide-angle lens. This lens is excellent for nightscapes thanks to its bright aperture and clean optical design, which helps preserve star shapes and capture faint details in the sky.

In both images you can see a faint green glow near the horizon. This is not light pollution — it is airglow, a natural atmospheric emission that becomes especially visible in true dark-sky locations like Yellowstone.

Big Dipper and Old Faithful

In this first image the Big Dipper appears clearly in the middle-right part of the frame. On the left side, the geyser’s steam rises high toward the upper edge of the photo, adding movement and depth to the scene. The wide-angle composition allows both the landscape and the constellation to be captured in a single frame without distortion.

The clarity of the stars together with the drifting steam and natural airglow creates a surreal atmosphere that only a dark, quiet night in Yellowstone can offer.

The second image was taken from a greater distance, showing the geyser basin more fully. Here the entire Big Dipper stands over the geyser steam, and the wider view reveals more of the sky’s natural airglow. The combination of drifting steam, cold night air, and a pristine dark sky creates an amazing, almost magical atmosphere in the photo.

Yellowstone Milky Way



Milky Way in the Yellowstone National park is amazing. I was three days in Yellow stone, first day in Yellowstone Lake Hotel, next day in Mammoth hotel and last day in Old Faithfull hotel. First two night and days it was raining and I missed nice views which I saw in the photos of other people. Finally I was lucky near Old Faithfull Geyser. Sky is so dark that stars looks like lamps and Milky Way is really just fantastic!

Yellowstone Astrophotography

During my trip to Yellowstone National Park the weather was mostly cloudy and rainy, and for several days I thought I would not be able to photograph the night sky at all. Yellowstone is famous for dramatic weather changes, and this trip proved it. Clouds, fog, and rain covered the park almost continuously. 


Only on the very last night, shortly before midnight, the sky suddenly cleared for a couple of hours. It felt like a miracle. I rushed outside with my camera, knowing this might be my only chance. By the next morning it was raining again — so I was extremely lucky to catch this short window of perfectly clear sky.

Yellowstone is one of the darkest and most impressive places I have photographed. The quality of the sky is excellent, with very little light pollution, and the combination of geothermal features and the Milky Way creates a truly unique atmosphere. All images were taken with a Canon 60Da camera paired with the Canon EF 16–35mm f/2.8L II USM ultra-wide lens, a great setup for capturing wide night landscapes. Exposure time 30 sec; f/2.8; ISO 4000. 
One of the most surprising and beautiful elements in these photos is the foreground. Normally, it is very difficult to capture natural color and detail on the ground at night. But in this case, soft light from the nearby hotel illuminated the grass and the area around Old Faithful just enough to make it visible, without overpowering the stars. This gentle lighting worked perfectly and added a sense of depth to the landscape.

Seeing Old Faithful Geyser under the stars was unforgettable. The steam rising into the cold night air, the illuminated grass in the foreground, and the star-filled sky above created a scene that looked almost prehistoric — like the Earth a million years ago. The combination of geothermal activity and a dark, crystal-clear sky made the whole landscape feel timeless.
This short window of clear sky turned what I expected to be a completely cloudy trip into one of the most memorable astrophotography experiences I have had. Yellowstone at night is magical, and I hope these images capture a little of that feeling.

Canon 60Da Milky Way Tripod Ultra Wide Angle Astrophotography Summer Triangle

This is my first deep and detailed Milky Way photo captured with the Canon EOS 60Da. I took this image in the Catskills, Upstate New York, under much darker skies compared to Brooklyn. The 60Da’s enhanced H-alpha sensitivity and special IR-cut filter reveal far more Milky Way structure than my older Canon 40D ever could.

Using an ultra-wide-angle Canon EF 16–35mm f/2.8L II lens on a fixed tripod, the 60Da captured thousands of faint stars and intricate nebulae in a single wide field centered on the Summer Triangle (Vega, Deneb, Altair).

Constellations and Deep-Sky Objects Visible

This wide field contains an incredible number of stars — my software detected over 10,000 stars in a single frame. It covers many constellations:

  • Cygnus, Lyra, Delphinus, Lacerta, Sagitta
  • Parts of Cepheus, Equuleus, Pegasus, Draco, Aquila

Several famous deep-sky nebulae and clusters are visible, including:

  • IC 1396 – Elephant’s Trunk Nebula
  • NGC 7000 – North America Nebula
  • IC 5070 & IC 5067 – Pelican Nebula
  • IC 1318 – Gamma Cygni Nebula
  • IC 5146 – Cocoon Nebula
  • IC 1311 – Sadr Region
  • Veil Nebula (supernova remnant)
  • Dark nebulae: Triple Cave (Aquila), Le Gentil 3 (Cygnus)
  • Beginning of the Great Rift in the Milky Way
  • Open clusters: M29, NGC 6885, NGC 6940
  • Brocchi’s Cluster (Coathanger)

The daytime photo of the setup shows the full equipment used for this shot: the Canon 60Da mounted on a sturdy tripod, a remote interval timer for consistent exposures, and an anti-dew heating strip (Dew-Not) wrapped around the lens. Dew control is especially important during summer nights in the Catskills to keep the lens clear for long imaging sessions. This simple and portable setup is ideal for wide-field Milky Way photography when traveling without a star tracker.

The annotated version of the Milky Way image shows just how rich this region of the sky is. By labeling the nebulae, dark clouds, open clusters, and constellation patterns, the annotation helps visualize how much structure the Canon 60Da can capture with only a fixed tripod and a wide-angle lens. It also highlights how well the 60Da’s enhanced H-alpha sensitivity brings out emission nebulae like the North America Nebula, Pelican Nebula, Gamma Cygni region, and Cocoon Nebula.
