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 Solar Eclipse April 8, 2024 during totality, seen from Westport, New York

Solar corona images of Total Solar Eclipse April 8, 2024 over Westport, New York


This composite image captures the ethereal beauty of the total solar eclipse on April 8, 2024, through a series of meticulously planned exposures. The photos were taken using a Canon Ra camera, renowned for its astro-imaging capabilities, paired with an EF200mm f/2.8L II USM lens and a 2x III extender, enhancing the camera’s ability to capture the fine details of the solar corona. To accommodate the wide dynamic range of the corona's light, nine different shutter speeds were utilized: 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, and 1/4 seconds, all at ISO 200.

Mounted on an iOptron SkyTracker, the setup ensured that each exposure was free from the blur that could be caused by the Earth’s rotation, providing a clear and steady view of the eclipse as it progressed. The use of a SET'n'C (Solar Eclipse Timer and Controller) allowed for precise control over the timing and execution of each exposure, crucial for capturing the fleeting moments of the eclipse with accuracy.

The final composite showcases the solar corona in unprecedented detail, from the bright light surrounding the sun to the outermost wisps of plasma stretching into space. The range of exposures reveals the corona’s complexity and the subtle nuances of its structure, creating a stunning visual representation of this awe-inspiring celestial event. This image stands as a vivid reminder of the eclipse’s grandeur, preserving the moment with clarity and detail that convey the majesty of the cosmos.

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.
