The Solar Eclipse of April 8, 2024: An HDR Revelation of the Sun's Corona from Westport, New York

The creation of High Dynamic Range (HDR) images of the solar corona is a fascinating challenge, driven by the need to capture the vast dynamic range of brightness that defines these celestial phenomena. This endeavor marries the artistic with the scientific, uncovering details and structures of the corona that a single exposure could never reveal.

 

The Solar Eclipse of April 8, 2024: An HDR Revelation of the Sun's Corona from Westport, New York

This particular HDR image of the solar corona was meticulously crafted from a series of exposures captured during the total solar eclipse on April 8, 2024. My setup for totality included a Canon Ra camera, a Canon EF200mm f/2.8L II USM Lens paired with a Canon 2x III Extender for an effective focal length of 400mm, set at F/8, ISO 200. The camera was mounted on an iOptron SkyTracker, and I utilized a laptop with the SET'n'C (Solar Eclipse Timer and Controller) for precise camera control. The range of exposure times spanned from 1/1000 to 4 seconds, encompassing 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1, 2, and 4 seconds.

During the eclipse, I successfully captured four complete series of photos at these shutter speeds, all in CR3 format. I then processed these files in a Raw editor, adjusting texture, clarity, and denoise settings before saving them as 16-bit TIFF files.

In Photoshop, I centered the photo by loading the images into layers (File > Scripts > Load Files into Stack...) and utilized the “difference” blending mode for layers, manually centering each image using the arrow keys. An average shift calculation from image to image helped address the challenge of centering overexposed images, which could not be simply aligned based on the moon alone.

To create a mean image, I converted the selected layers into a Smart Object and applied the Mean stack mode (Layer > Smart Objects > Stack Mode > Mean), then flattened the image and saved it as mean.tif. For the moon to be at the center of the image, I cropped it accordingly.

I applied a Radial Blur in Photoshop (Filter > Blur > Radial Blur) with the settings: Spin as the Blur Method, Best for Quality, and an Amount of 10, ensuring the moon was centered in the image. This blurred image was saved as blur.tif.

To subtract the blurred image from the original, I used the Apply Image command (Image > Apply Image), setting the source to blur.tif, with the blending mode set to Subtract and an offset of 128. I then compressed the dynamic range using the Levels tool (Image > Adjustments > Levels) and saved the file as subtract.tif.

Clarity Unveiled: High Pass Filtering by Subtracting Radial Blur from the Original

To multiply the mean image with the subtracted image, I once again used the Apply Image command, setting the blending mode to Multiply. The final image was saved as done.tif.

Final touches were made using Topaz Denoise, the Raw Filter editor, and other Photoshop tools to enhance the image.

The final HDR composition is not merely a visual feast but a technical triumph that reveals the complexity and elegance of the sun's atmosphere. These images are invaluable, providing insights into solar physics and the forces that shape the corona. They also offer a breathtaking visual experience that conveys the awe-inspiring beauty of solar eclipses to a global audience. Through this HDR image, the profound beauty of a transient celestial moment is captured, enriching our appreciation and understanding of the cosmos's wonders and presenting the solar corona in a captivating new light.

The comet, named "SOHO-5008", was discovered earlier that day by the vigilant eyes of amateur astronomer Worachate Boonplod. He spotted it in the images captured by the Solar and Heliospheric Observatory (SOHO) coronagraph, marking the beginning of an unexpected celestial narrative. News of the discovery spread quickly, and astronomer Karl Battams of the Naval Research Lab highlighted the potential for ground-based observations during the eclipse. "Ground-based observations of sungrazing comets are extremely rare, so this would be a great opportunity to see an eclipse comet!" Battams had remarked, setting the stage for a once-in-a-lifetime observation.

The capture of comet SOHO-5008 during the solar eclipse is a poignant reminder of the ephemeral nature of our universe. Just as the eclipse brought darkness to the day, it also brought to light a comet on its final voyage. This celestial coincidence underscores the value of staying present and prepared—for in the world of astronomy, as in life, some of the most fascinating moments are those that are unplanned and fleeting.

Baily's Beads - Total Solar Eclipse April 8, 2024

 

Baily's Beads occur just before and just after totality of a solar eclipse. As the moon moves to cover the sun completely, the rugged lunar topography allows beads of sunlight to shine through in some places and not in others. These beads of light appear to flicker around the moon's edges and are named after Francis Baily, who provided an explanation of the phenomenon in 1836.

This is beginning of Total Solar Eclipse visible from Westport, New York April 8, 2024.

Baily's beards image sequence

Image sequence of Baily's beads (diamond ring) at the second contact was captured with Canon Ra with an EF200mm f/2.8L II USM lens and a 2x III extender.  Camera was mounted on an iOptron SkyTracker and orchestrated by SET'n'C (Solar Eclipse Timer and Controller). The six exposures were all short at 1/1000, ISO 200 with camera drive set on continuous at 1 frame per second. 

The beauty of Baily's Beads lies in their rarity. Solar eclipses themselves are rare events at any given location, and the Baily's Beads effect is visible for only a few seconds during the partial phases of an eclipse.

The Baily's Beads effect is a powerful reminder of the celestial mechanics at play. It highlights the perfect alignment of the Earth, Moon, and Sun, and showcases the irregular, rugged terrain of the Moon—factors that are both scientifically fascinating and visually captivating. The sequence of images not only serves as a document of a specific astronomical event but also as an artistic representation of the dynamic, ever-changing nature of our universe.

In essence, a sequence image of Baily's Beads captivates by blending the precision of astronomy with the wonder of natural beauty. It freezes a moment of cosmic ballet, offering a glimpse into the sublime, ephemeral interplay of light and shadow, celestial bodies, and the laws of physics—a dance that, despite its brief appearance, leaves a lasting impression of the awe-inspiring universe we inhabit.

Camera set up for Annular Solar Eclipse

There are photos of Crescent-shaped shadows.

Using a kitchen colander during a solar eclipse is a fun and educational way to witness the celestial event. When you hold a colander up to the sun, its numerous small holes act as pinhole cameras, projecting multiple images of the crescent-shaped sun on any surface below, whether it's the ground or a piece of paper. The result is a pattern of miniature eclipses resembling a celestial sieve.

Crescent shadows through the holes in the colander that occur during the eclipse


As the moon begins its journey across the sun's face, the gaps between leaves on trees act as pinhole cameras, casting crescent-shaped images of the partially covered sun on the ground below. These shadow crescents mimic the sun's diminishing shape in real-time, creating a dynamic and awe-inspiring display. In addition to crescent-shaped gaps, the overall dappled pattern of light passing through the leaves forms intricate designs on the ground. The gaps between the leaves project countless images of the partially eclipsed sun, producing an artistic tapestry of sunspots.

Magdalena Astronomy Club - Interpretation of time diffraction

 Can the future interacting with the past create the present?


Astronomer Figurine in Magdalena Astronomical Lyceum

In classic Newton mechanics answer is no. It is contradict the causality principle. But in quantum mechanics situation is much more complex. 

Just read article "Double-slit time diffraction at optical frequencies" which was published in Nature Physics April 03, 2023. Photons in future and past coming through Double split in time are creating diffraction in the present, and this is not theory - it is result of experiment!


Magdalena Astronomical Society_Astronomical Lyceum

I tried to explain it. First thinking about fantasy books which I read when was young. In this book people go to the past and after that return to the present and see that present was changed. Second thinking about retrocausality. It is opposite effect when the future changes the present. But interaction of the future and the past? 

Magdalena Astronomical Club

In the same time I thinking about Astronomical Club in Magdalena. And in some moment I got how to explain time diffraction. The future is The Karl G. Jansky Very Large Array (VLA), past is history of Magdalena city, near VLA, and current is the Astronomical club.

Astronomical Lyceum

The VLA, Magdalena's history, and the Astronomical Club of Magdalena all illustrate how the future can interact with the past to create the present. 


Magdalena Astronomical Society

The VLA's cutting-edge technology builds upon the advancements of the past while paving the way for future discoveries.

The Karl G. Jansky Very Large Array (VLA)

 

These photos from my travel trip to New Mexico Very Large Array. 

The Karl G. Jansky Very Large Array (VLA) is a radio astronomy observatory located in central New Mexico, USA.


The Karl G. Jansky Very Large Array (VLA) Sign at Night

The VLA was first proposed in the 1960s as a replacement for the older National Radio Astronomy Observatory (NRAO) antennas. Construction began in 1973, and the VLA was completed in 1980. The VLA consists of 28 dish antennas that can be arranged in different configurations to observe different parts of the sky.


Radio Telescope at Night

The VLA is a powerful tool for radio astronomy, as it is capable of observing a wide range of celestial objects, including stars, galaxies, and black holes. Because the VLA observes in the radio frequency range, it can see through dust clouds and other obstructions that would be opaque to visible light telescopes. 

VLA Radio Telescope at Night

One of the most famous scientific discoveries made using the VLA was the confirmation of the existence of black holes. In 1974, astronomers using the VLA observed a radio source called Cygnus X-1, which was suspected to be a black hole. By observing the orbital motion of a companion star to Cygnus X-1, the astronomers were able to confirm that it was indeed a black hole.

Sky Reflection - Crystal Ball

In addition to the discovery of black holes, the VLA has made many other important scientific discoveries. For example, in 1998, astronomers using the VLA discovered the first radio-emitting magnetar, a type of neutron star with an extremely powerful magnetic field. The VLA has also been used to study the properties of interstellar gas and dust, as well as the formation of stars and galaxies.


VLA Sign

The Karl G. Jansky Very Large Array (VLA) was also featured prominently in the 1997 science fiction film "Contact", based on the novel by Carl Sagan. The film tells the story of a scientist named Ellie Arroway, played by Jodie Foster, who uses the VLA to search for extraterrestrial intelligence.

NRAO

In the film, Arroway and her team use the VLA to search for signals from other civilizations in the universe. The VLA's ability to detect faint radio signals from distant objects is crucial to their search, as they believe that other intelligent beings may use radio waves to communicate with one another.

Radio Telescope

"Contact" is a science fiction film that features the Karl G. Jansky Very Large Array as a key element in its plot. Although the film's depiction of the VLA is largely fictional, it did raise awareness of the observatory and its capabilities among the general public. The VLA remains a powerful tool for scientific research, and its ongoing use by astronomers and other scientists continues to expand our understanding of the universe.

VLA

I have only one day and night to make photos. Weather was not perfect. But I thing clouds give some drama to these photos.
