Description

To-date, Star HD 148937 is believed to the be the only magnetic O-type star known to be surrounded by a nebula. At a size 40 times as massive as our own Sun, HD148937 is rare, hot and quite the spectacular artist!

What makes HD 148937 so interesting is that it is, by far, the most massive Galactic star with a detected magnetic field, and this has given rise to studies (Mahy et al. 2016) focusing on the evolutionary state of not just the star but its close bipolar ejecta nebula: NGC 6164 and NGC 6165 (known to comprise "The Dragon's Egg") and their formation as circumstellar nebulous regions. When considering this target, more time was given to OIII integration (> 28 hours) to emphasize the blue halo, the ellipsoidal wind-blown shells. As NGC 6164 & NGC 6165 are relative bright, less than 8 hours for both Ha and SII were integrated to showcase the ionized nebula's - almost a figure "8" shape - spherically symmetric Strömgren sphere.

The image presented and its data was captured over several evenings during the 20th May 2023 through to the 14th July 2023; each night taking advantage of when the moon was below the horizon. What I love most about the The Dragon's Egg is that the star HD 148937 is still in it's prime, leading researchers to believe the creation of its surrounding ionized gasses to be due to the star's high rotation rate, expelling materials during earlier high-activity phases to create the beautiful blue halos and the magnetic field driven inner egg coining its name.

Description:

The Whirlpool Galaxy, also known as Messier 51 (M51) or NGC 5194, is a spiral galaxy located in the constellation Canes Venatici. It is one of the most famous galaxies in the night sky due to its striking appearance and its interaction with a smaller companion galaxy, NGC 5195.M51 was discovered by the French astronomer Charles Messier on October 13, 1773. Messier initially described it as a "very faint nebula without stars." However, in 1845, the English astronomer Lord Rosse observed M51 with his newly constructed 72-inch telescope and was able to discern its spiral structure, making it one of the first galaxies recognized as having a spiral shape. Although a 72-Inch wide aperture sounds otherworldly to modern day amateur astronomers like myself, it is still possible, thankfully, to discern much of the structure of this majestic galaxy with a telescope as small as a 9.25 inch SCT.

2024 Solar Eclipse: Totality by Harley Grady, on Flickr

Totality and the Diamond Ring from the April 8, 2024 eclipse in Hillsboro, TX. So glad the clouds held off just enough! Was an amazing experience.

Shot on a TS Optics 90mm CF APO refractor and Fuji XH2.

April 8th, 2024 : Solar Eclipse Totality ' Earth Shine" by Harley Grady, on Flickr

April 8th, 2024 : Solar Eclipse Totality "Earth Shine". One of the interesting phenomena that can be captured during a total solar eclipse is "Earth Shine". Earth shine is the faint illumination of the new moon reflecting light from the earths surface. I wanted to try this after photographing the 2017 eclipse and because of the duration here in Hillsboro, Texas I had plenty of opportunity to get the exposures needed. This is a combination of five exposures blended together. Glad we had cleare nough skies at the @superbloomsfarm to get the shot! . Shot on a @TS Optics 90mm CF APO refractor and @fujifilmx_us XH2. Guided with a @skywatcherusa EQ6R Pro.

Photo of the eclipse taken in Flower Mound, TX. I think this is a great combination of several of the major features of a total solar eclipse, all in one single exposure: a bit of the diamond ring, bailey's beads, prominences, and coronal structure including some visible magnetic field lines! Shot through a 400 mm lens with 1.7x teleconverter, for 650 mm at f/5.

A Phoenix Rising over Lac Megantic
Today a total solar eclipse shone over a rural Quebec village that was all but destroyed 11 years ago. A run away train car started a massive explosion in the town centre that killed 47 people, turned the town to ashes, and remains the worst Canadian train disaster in our history.
A population with deep pain and trauma, ( the town still has regular loud trains passing through every few hours) came together today and watched a true miracle, the joyous event of the moon's shadow passing over us as the moon blocked the sun for 3 minutes 36 seconds.

Even though the temperature dropped at least 8 degrees Celsius, the villagers and visitors cheered, and played music and children blew soap bubbles in excitement. All were united and mesmerizer by this celestial event. I hope some were also comforted in the embrace of their community.

We met so many wonderful people, and loved every minute of this special day in a very special place.

Description:
SNR G065.3+5.7 is the remnant of a supernova located in the constellation Cygnus, near the border with Vulpecula (the Little Cygnus Veils).
- It spans an area of approximately 4.0×3.3 degrees in the sky and has a diameter of about 230 light-years.
- The shell is primarily composed of OIII emissions, with some H-alpha signal.
- SNR G065.3+5.7 was discovered during the study of the Milky Way in the OIII channel by Gull, Kirshner, and Parker in 1977.
- Some parts of the SNR were previously cataloged by Stewart Sharpless in his SH2 catalog as SH2-91, SH2-94, and SH2-96, but they were not recognized as part of a larger structure.
- The age of the object is estimated to be 20,000 - 25,000 years, and it is located at a distance of approximately 2600 – 3200 light-years from Earth.
- The red star near the center is the planetary nebula PK064+05.1 - Campbell’s Hydrogen Star.

The object is also known by the name G65.3+5.7

The Eye of Earth — Moon's Shadow During Total Solar Eclipse



Description:
These two photos were taken from 35,000 meters above San Antonio, Texas, using a high-altitude balloon and represent a two-year journey from conception to realization, capturing the Moon's shadow on Earth during the total solar eclipse, creating a stunning visual reminiscent of Earth's eye looking back at us. The equipment, designed and assembled by us, not only captured this moment but also safely returned, allowing us to share this unique perspective.

The Hunt for the Devil - 12P/Pons–Brooks

The Hunt for the Devil - 12P/Pons–Brooks by Ahmed Waddah, on Flickr

I travelled over 500 kilometers from Cairo to a bortle 1 location in Al Wady Al Gaded Desert in New Valley government near the White Desert to have a final chance to catch comet 12P/Pons–Brooks - Devil Comet. It's a periodic comet with an orbital period of 71 years. I set up in front of a dune just about an hour before sunset and was able to get 35 images of 30 seconds each before the Devil comet set behind the dune. Both sky and foreground images were shot from the same position using the same camera and scope , the Askar FMA 180Pro. I had a friend walk up the dune just before sunrise to get the foreground image. The final image is a composite of both sky and foreground images.

Definitely a once in a lifetime ☄

The Glory of Totality

Each step of a total eclipse has a special moment. When the moon has almost covered the entire sun, a bright glare flares out in a blinding diamond ring, at the beginning and end of totality.

In between, the last rays of light from our sun peek out though the craters and mountains of the moon (helped by the massive sun prominences this day). Those dots of red are called “Baileys Beads”

And the heart of totality, that moment when you can take off your solar glasses and see the full glory of the Corona that surrounds the sun.
Normally we cannot see the corona as the main disk of the sun is too bright. Only during totality can we see its whispy glory.

Imaged at 400MM with a D750
Very short exposures for the ring and beads, longer exposures to show the expanded corona.

On our beautiful day in Lac Megantic, Quebec, April 8th 2024.

Total Solar Eclipse and the Adirondacks

Click to view full size image

A total solar eclipse is a life changing event. Hiking 2 miles in the snow with all photography equipment just to have a view of the Adirondacks' High Peaks on April 8th, 2024 was truly a bold and wise choice. As it is seen, the composition of the Mount Van Hoevenberg and the High Peaks located in Lake Placid, NY, with the totality - also showing a bright Venus and a redish horizon, as if there was a sunset wherever one looked at - was absolutely breathtaking and made every step of the trail worth. I came all the way from Rio de Janeiro, Brazil, just to witness a total solar eclipse and take the photo I have always dreamed of.

This photo was taken with a Sony A7 II camera, a 24-240 lens at 24mm and a tripod. It is a HDR image, with photos ranging from 0,25 to 15 seconds of exposure. The location is the Balanced Rocks at Pitchoff Mountain, in Lake Placid.
