Milky Way and a Fisheye Lens

I have taken countless photographs of the Milky Way using anything from ultrawide to telephoto lenses. But I have never taken a photograph of the Milky Way with a fisheye lens until now.

I like the result because it shows a large part of the Milky Way from south of the Galactic Center northward almost–but not quite–to Cassiopeia. Cygnus can be seen in the center.

As a bonus there is some banded airglow along the eastern horizon.

SpaceX/Falcon 9 De-Orbit Burn–III

Here are a few more SpaceX Falcon 9 deorbit burns observed over Arizona during the latter half of May.

SpaceX has launched frequently during this time period and many of the flights pass over the southwest United States and Arizona. The timing of the deorbit burn is fortuitous as it occurs just as the 2nd stage of the rocket appears above the western horizon and continues until it is near the zenith. This results in very favorable conditions for taking photographs and video of the event.

I have used both ultra-wide angle and fisheye lenses and really like the result from the latter as it is able to capture the lake reflections as well as the entire burn even as it passes overhead. One time I used a short telephoto (80mm); I may try this again.

Some of the images use 30-second exposures while others use a very short 2-second exposure which is useful for creating time-lapse video.

It’s interesting how all the image and videos show a burn that ends as it approaches the zenith followed by a splash of color as it moves overhead and leaving a circular red patch in the sky. It’s possible that the red is from the chemical reaction of the exhaust gases with the ionized air in the ionosphere. This red coloring of the ionosphere has been noted before with launches ascending into orbit so it is possible that the same chemical reaction takes place on descent.

The Great Aurora Storm of May10-13, 2024

The beginning of a strong substorm of actiivity. Some of the best and brightest colors occurred at this time.

It has been called the Great Aurora Storm of 2024 and it occurred on May 10–13 with the peak occurring on May 10–11. It was seen across high, middle, and even low latitudes and it was the strongest geomagnetic storm in decades. From the NASA science site:

May 2024 has already proven to be a particularly stormy month for our Sun. During the first full week of May, a barrage of large solar flares and coronal mass ejections (CMEs) launched clouds of charged particles and magnetic fields toward Earth, creating the strongest solar storm to reach Earth in two decades — and possibly one of the strongest displays of auroras on record in the past 500 years.

At its most intense the event was classified as a G5-class geomagnetic storm (Kp = 9).

We were in Colorado at the time visiting family and I only carried a Sony RX10, a camera with a 24–200mm zoom at constant f/2.8 aperture. It’s a good camera but doing long exposures at high ISO at night is not its strong point. Well, you’ve probably heard the saying: “the best camera is the one you have with you.”

Looking to the south as the aurora reached and passed the zenith. The rapid motion in the aurora was fantastic.

So I used what I had with me. The results were mixed. Some of the images are noisy at high ISO settings. Some of the long-exposure images show tripod shake resulting in streaky stars. And so on.

There have been some amazing photographs published on social media sites–including a shot that I have been trying to get for the past few years of increasing auroral activity.

Ah, well. We still haven’t hit the solar max which is expected between late 2024 and early 2026 so there will be other opportunities.

So here are some photographs taken from our location in northeast Colorado.

SpaceX/Falcon 9 De-Orbit Burn

I have posted several images here of the launch of SpaceX/Falcon 9 rockets from Vandenberg Space Force Base in California. These are easy to see during morning and evening twilight hours. They are less easy to see at night and quite difficult (but not impossible) to see during the day.

Until recently, I had never seen nor photographed a de-orbit burn on the second stage in preparation for atmospheric reentry. A few photographs have shown up from time to time—the most recent from a launch just a few weeks ago. It turns out that yesterday’s launch (12 April) was very similar: launch from Florida in the early evening, deploy Starlink satellites while over the Pacific Ocean, and then initiate a de-orbit burn as it crosses the west coast and moves across the southwest.

With this information I made a guess at what time the Falcon 9 second stage would move over Arizona and start the burn. I was only off by a few minutes so it was a good guess.

I shot with a wide-angle lens to ensure that my field of view was wide enough to capture the event (it was, until it moved overhead). We could see a small point of light that was both the cluster of 23 Starlink satellites and the second stage booster. Suddenly, it brightened significantly signaling the start of the burn. It was very bright as it moved overhead. At this point, I was not able to photograph it anymore. And that’s too bad because that’s when it got really interesting. For about 20–30 seconds it was like a puff of glowing gas moving across the sky. Really amazing! It ended quickly as the booster moved into Earth’s shadow and the light show was over.

I will probably do things differently if I get another chance. Maybe shoot video? Telephoto lens? Shorter exposures? All or none of the above?

Comets, Sunspots, and Zodiacal Light

There have been few opportunities for capturing night sky objects owing to clouds and the presence of the Moon. That doesn’t stop me from trying.

Clouds, a bright waxing Moon, and some distant light pollution made it difficult to capture this comet. This was taken at the base of Arizona Snowbowl ski area at 2830 m; the elevation helps to get above some of the atmospheric haze.

Sunspots AR3615 and AR3614

Several large sunspots are visible on the face of the Sun (27 March 2024).

While setting up to photograph a launch at Vandenberg SFB (which was scrubbed), I fired off a few test shots of the zodiacal light. In review, I noticed that I also captured Comet 12P/Pons-Brooks. Small–very small–when shot with a 24mm wide-angle lens.

Now, the Moon is out of the way and the forecast indicates a few clear nights so maybe I’ll get another change to shoot some images of the comet.
