The conditions were ideal for imaging the Sun on May 29th 2023, 100 km north of Venice, Italy.
In those precious 14 minutes the atmosphere didn't play any tricks on the Sun light that travelled to my telescope and I was able to collect 20 x 5000 frames high quality videos of AR13315 and put together this animation:

Story:
In this panoramic shot captured on the Stokksnes peninsula we can see in the sky a lower green/yellow arc of the aurora borealis over Vestrahorn mountain, a larger and more diffuse arc in red/pink tones and the arc of the Milky Way crowning this amazing night view from Iceland.
We also highlight some elements of the night sky visible in the image, such as: the planet Mars, the Andromeda galaxy, the North America nebula and the stars Vega, Deneb, Capella and Menkalinan.
This image is a single-exposure panoramic, when the sky and terrain are captured at the same instant. To make this image, 16 captures were made, divided into 2 lines of 8.

Mille fleurs de l'Eden by Marion Kabac, sur Flickr

"I broke the mirror, I gone through the wave of an inverted world, and I gathered the thousand flowers of Eden."
Once upon a springtime, the starry sky was reflected in the mirror waters of lake, like thousand water lilies flowers. The idea came to me to create a nightscape with the lake alone, not the sky itself.
The foreground - grass and water - was in complete darkness, so a 30 seconds exposure was necessary. I chose to wear a white dress, so I could light up the scene. The lying-down posture makes it possible for me to stay perfectly still for the long exposure.

From: California, USA

Using two different telescope and filter combinations I was able to capture the ISS as it transits the solar surface in high detail. Using white light to capture the ISS detail, and more importantly to have a shutter speed fast enough to freeze the ISS given its speed of 59.7'/s. Along with a hydrogen alpha double stacked telescope configuration I'm able to capture the Sun's chromosphere to highlight some beautiful detail of our beautiful star.

Vela Molecular Ridge

The Vela Molecular Ridge are interstellar clouds covering the north western side of the constellation of Vela and the eastern side of Puppis. From left to right we have Gum 17, Gum 15 and Gum 14. Part of the gas in the clouds are ionized by the ultraviolet radiation coming from massive stars associated with the complex, constituting H II regions of great extent. At the lower right we have some filaments wich are part of the Vela Supernova Remnant.

THE JEWEL BOX

Also known as the Kappa Crucis Cluster or Caldwell 94. NGC 4755 is a brigth open cluster in the constellation Crux. Originally discovered by French astronomer Nicolas Louis de Lacaille in 1751–1752. This cluster was later named the Jewel Box by John Herschel when he described its telescopic appearance as "...a superb piece of fancy jewellery". It is easily visible to the naked eye as a hazy star some 1.0° southeast of the first-magnitude star Mimosa (Beta Crucis)

Story:
Vestrahorn Mountain, located in Iceland, is a breathtaking natural wonder. With its imposing black rock ridges and black sand beach, it captivates visitors with its unique beauty. The stark contrast between the dark mountain peaks and the black sand creates a visually striking scene. Vestrahorn is a popular destination for nature lovers and photographers seeking to capture the magnificence of this fascinating landscape, offering a truly memorable experience.
The Aurora Borealis, also known as the Northern Lights, is a mesmerizing celestial phenomenon that graces the night skies in polar regions. This dazzling display of lights is a result of interactions between the Earth's magnetic field and charged particles from the sun. One of the most enchanting aspects of the Aurora Borealis is its vibrant array of colors. The dancing lights can appear in hues of green, blue, red, yellow, and even purple. The green color, the most common, comes from oxygen molecules approximately 60 miles above the Earth. The different colors are produced by variations in altitude and the type of gas particles involved in the collision. Each color adds its own magical touch to the spectacle, painting the night sky with an ethereal and ever-changing palette. Witnessing the vivid colors of the Aurora Borealis is a truly awe-inspiring experience that leaves a lasting impression on all who have the privilege to see it.

Circumhorizontal arc over Modica

I am thrilled to share with you a collection of photographs showcasing the wondrous phenomenon of the circumhorizontal arc gracing the panoramic view of Modica. These images beautifully merge scientific intrigue with the inherent beauty of this charming city.
The circumhorizontal arc, affectionately known as the "smile of the sky," forms an arc resembling a radiant grin above Modica. This celestial phenomenon, resulting from the intricate science of light diffraction, adds an extra layer of enchantment to Modica's allure.
In these photographs, the circumhorizontal arc unveils itself as a celestial masterpiece. Its vibrant hues, ranging from intense blues to soft pastels, blend harmoniously with Modica's architectural wonders and rich heritage. It is as though nature collaborates with the city, creating a breathtaking fusion of art and science.
As sunlight dances through ice crystals within cirrostratus clouds, the ethereal arc suspends itself above the zenith, establishing a celestial connection between the heavens and the earthly splendor of Modica. The arc's graceful curve complements the city's historic skyline, accentuating its architectural treasures. It is as if nature pays homage to Modica's cultural significance, UNESCO world heritage.

Summer Milky Way Rising Above Mono Lake California


My Tour To The South West USA to the most darkest places california
one of the Most Darkest Skies in the world is in Mono Lake with outstanding
sky quality metering magnitude scale of 21.99!
keep in mind that a number of 22.00 represents the least luminance—in other words, the least light pollution in the world.

Mono Lake Sand Tufa is a saline soda lake in Mono County, California, formed at least 760,000 years ago.Mono Lake Tufa State Natural Reserve is located near Yosemite National Park within Mono County, in eastern California the tufa,. Tufa is a highly porous, sedimentary rock (limestone) composed of calcium carbonate, CaCO3. It is formed by biological and chemical precipitation of Calcite or aragonite from cold, supersaturated surface or ground waters All tufa at Mono Lake forms underwater. Beneath Mono Lake, calcium-rich freshwater springs seep up from the lake bottom and mix with lake water rich in carbonates , a tufa tower will grow. Tufa towers can grow to heights of over 30 feet underwater.


i managed to capture AirGlow in mono lake, Airglow Is normallyey green and red and yellow, commonly visible in Bortle 1 Dark sky i was lucky to capture it in an amazing green airglow in a dark night in the new moon of may 2023

O and I
Copyright: György Soponyai

If we look up and follow the path of the Sun's position, usually we can draw a letter "C" to the sky. However there are locations on the Earth (the Polar Regions and the Equator) where sometimes you can draw other letters than "C" by using the same process.

The left picture -- depicting a letter "O" -- was taken atop Storsteinen mountain near Tromsø, Norway in June, 2019. The city lies 350 kilometers North of the Northern Polar Circle where the Sun does not set between 20th May and 22nd July. Standing at a mountaintop 24 hours for observing and capturing the Midnight Sun was not easy and comfortable but I guess it was worth it.. The foreground photo was taken at local midnight (00:45).

The right picture -- a letter "I" -- was taken three days before Spring Equinox in 2023 from Singapore. This small city-state lies in the proximity of the Equator, where celestial objects rise and set vertically, and where the Sun climbs to the Zenith on the days of Spring/Autum Equinox. (On this photo the Sun climbed "only" to 89° instead of 90° but I did not see my shadow)

The "dots" of the solar disk were taken with the help of a solar eclipse watching filter in every 20 minutes.

Image Description:
The Pelican Nebula lies 1800 lightyears away located in the constellation of Cygnus. The nebula gets its name from its resemblance to the pelican, with its long "neck", and rounded "head", extending from a bright "eye" region. This object is an emission nebula full of ionizing gases and dust that make it very bright. It has a very active mix of star formation and gas clouds that are constantly evolving.

Basic Image Capture Details:
- 7 hours of exposure across two nights
- Ha, O3, and S2 narrowband filters used
- Processed in PixInsight

Enjoy!

M90 and IC 3583 (Arp 76)

M90 (also known as NGC 4569) is a spiral galaxy that is part of the Virgo cluster. It is sometimes referred to as an anemic galaxy because of a dearth of star formation in its spiral arms. This is related to the stripping away of interstellar gas and material (ram pressure stripping) from interactions with the intracluster medium. A January 2016 paper by Boselli, Cuillandre, Fossati, et.al. using the MegaCam at the Canadian-French-Hawaii Telescope describes the presence of “spectacular tails” of diffuse ionized gas extending from the disc of the galaxy (available at: https://arxiv.org/pdf/1601.04978.pdf).

M90 is one of the few galaxies that exhibit a blue-shifted spectrum indicating a net motion in our direction within the Virgo cluster. M90 is about 59 million light-years away from Earth.

Irregular galaxy IC 3583 is visible to the right of M90 in this image. IC 3583 is about 30 million light-years away and may be gravitationally interacting with M90. Together the pair is listed in Halton Arp’s Atlas of Peculiar Galaxies as Arp 76. Many other galaxies are also visible in the image.

I hope you like the image!
