In the grand tapestry of the cosmos, few events capture the human imagination quite like a solar eclipse. While the Earth dances around the Sun, and the Moon orbits our planet, there comes a moment each year when these celestial bodies align in a breathtaking display of natural wonder. This momentous occasion is none other than the annual solar eclipse, a recurring phenomenon that continues to captivate, inspire, and remind us of the profound beauty of our universe.


The annual solar eclipse is not just an astronomical event; it's a celestial spectacle that has held a special place in human history and culture for millennia. As the Moon glides across the face of the Sun, it casts a shadow upon the Earth, temporarily plunging regions into darkness and transforming the day into night. The sun's corona, a delicate, fiery halo, emerges as the star attraction. People gather in awe to witness this cosmic alignment, pondering the mysteries of the heavens and feeling a deep connection to the vastness of the universe.

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.

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.

Testing for Solar Eclipse 2017, August 21 - Tellico Plains, Tennessee

"Whenever we want to watch an eclipse of the Sun 
we set out basins filled with oil or pitch, 
because the heavy liquid is not easily disturbed 
and so preserves the images it receives."

-- Seneca (Roman, 1st century AD)


There are some some photos which I did before solar eclipse, just for testing,  Canon 60Da,  Celestron Nexstar 4SE, Coronado SolarMax II 60.

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.

Totality HRD Image v.2

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.

Total Solar Eclipse - April 8, 2024 | Westport, New York


Total Solar Eclipse - April 8, 2024 -Westport, New York

On April 8, 2024, a celestial event of spectacular proportions graced the skies: a total solar eclipse. For those of us in Westport, New York, the day held an air of anticipation, excitement, and a touch of the ethereal, as we prepared to witness day turn into night under the eclipse's path of totality.

Westport, nestled along the scenic shores of Lake Champlain, became a buzzing hub for eclipse chasers, all eager for a front-row seat to nature's grand spectacle.

Westport Golf, known for its lush fairways and stunning views, offered a picturesque setting for eclipse viewing. The expansive greens provided a clear, unobstructed view of the sky, making it an ideal location for observation. As the eclipse approached, the course was transformed into a field of curiosity and excitement, dotted with telescopes, cameras, and spectators donning their eclipse glasses.

The darkness of totality was profound yet fleeting, lasting approximately 2 minutes and 40 seconds. During this brief interlude, the surroundings were bathed in a twilight glow, a surreal moment that felt out of place yet deeply moving. The visibility of stars and planets in the midday sky, particularly Venus’s bright appearance, added a stellar touch to the spectacle.

My set up for Totality: Canon Ra, Canon EF200mm f/2.8L II USM Lens + Canon 2x III Extender = 400mm, F/8, ISO 200. The precision with which these images were captured was further ensured by the use of an iOptron SkyTracker mount, which tracked the sun's movement across the sky, eliminating potential blurring from the Earth's rotation. Moreover, the integration of the SET'n'C (Solar Eclipse Timer and Controller) provided an automated approach to timing and exposure adjustments, critical for dealing with the rapidly changing light conditions during the eclipse.

Comet C/2023 A3 (Tsuchinshan–ATLAS) visible in NYC

Comet C/2023 A3 (Tsuchinshan–ATLAS) is making its grand journey through the inner solar system, inspiring astronomers, photographers, and stargazers around the world. As part of this collective fascination, I’m excited to share my photographs I captured of this remarkable celestial visitor against the vibrant cityscape of Brooklyn, NYC.

These photos are my small contribution to the ongoing global observation of this rare comet, offering a glimpse into how even from an urban environment, the wonders of space remain accessible to those with the patience to seek them.

Nestled between Staten Island and a boat drifting across the water, the comet adds a subtle glow beneath the iconic Verrazano Bridge, demonstrating the magic that can still be found in the night sky, even amid the city’s overwhelming lights.

The next photo dives deeper into the beauty of Comet C/2023 A3, revealing details not visible in the wide-angle city shot. Captured with a Canon EF 200mm f/2.8L II USM telephoto lens, the image showcases the comet’s bright, glowing tail and even a faint anti-tail.

The anti-tail is a fascinating feature that forms due to the unique alignment between the comet, the Sun, and Earth. While the main tail streams away from the Sun, the anti-tail appears to extend in the opposite direction. This is not because the comet has two tails going in different directions, but rather due to an optical illusion caused by our perspective. The anti-tail consists of dust particles along the comet’s orbit, which, under the right angle, seem to point sunward.

These images represent not just the beauty of the comet but also the joy of participating in a global observation effort. Whether observing from a dark, rural landscape or amidst the glowing lights of a bustling city, we all have the opportunity to look up and witness the universe unfolding before us.
