Milkyway core rising above valley Of The Moon in Jordan a.k.a Wadi Rum

Together with #sigma_israel exploring jordan supported by sigma offical and soon i will test the new Sony F1.4 14 mm prime!!

Story

Wadi rum is amazing place For astrophotography and i offer all astrophotographers to visit jordan that have one of the Seven Wonders of the World which is petra and not far away lays The Valley of the Moon in Jordan, also known as Wadi Rum, is a captivating desert landscape that showcases magnificent rock arches. These natural arches, sculpted by wind and water over millions of years, add a touch of wonder to the already breathtaking scenery. Among the notable arches in Wadi Rum are the Burdah Rock Bridge, Um Fruth Rock Bridge, and the Khazali Arch. Visitors can hike, climb, or take guided tours to witness the awe-inspiring beauty of these arch formations.

Wadi Rum offers a remarkable stargazing experience, particularly for those interested in observing the Milky Way. The remote location and minimal light pollution make it an ideal spot to witness the night sky in all its glory. With the vast expanse of desert as your backdrop, you can marvel at the celestial wonders above, including the Milky Way stretching across the darkness, revealing a myriad of stars, constellations, and celestial phenomena. Stargazing in Wadi Rum promises a truly enchanting and unforgettable encounter with the cosmos.

Solar prominence by Robert Parsons, on Flickr

I would like to share this spectacular Solar prominence from the 14th June 2023.
This image was captured from my backyard in Edinburgh, Scotland using a 120mm telescope fitted with a Quark chromosphere Hydrogen-alpha filter and an IMX174 camera.
The final image comes from a 3000 frame capture which was then stacked to the best 600 frames.

I have blocked out the solar disc (in the style of a coronagraph) to provide maximum contrast for the prominence.

MORE DETAILS
https://www.astrobin.com/full/s8woc8/0/

The Moon is usually seen in subtle shades of gray or yellow.
The different colors are recognized as corresponding to real differences in the chemical composition of the lunar surface.
The blue tones reveal areas rich in ilmenite, which contain iron, titanium and oxygen, mainly titanium, while the orange and purple colors show regions relatively poor in titanium and iron. The white/gray tones refer to areas with greater sun exposure.

Trifid Nebula - M20 by Ali Alobaidly, on Flickr

Trifid Nebula
https://www.astrobin.com/users/AstraPharma/

Copyright: Ali Alobaidly

Description:
The Trifid Nebula, also known as M20 or NGC 6514, is a beautiful and complex interstellar cloud located in the constellation Sagittarius. It is approximately 5,200 light years away from Earth and spans an area of about 40 light years in diameter.

The nebula is composed of a mix of gas and dust, with pink emission nebulae representing ionized hydrogen gas excited by hot, young stars and blue reflection nebulae reflecting the light of these same stars. The dark regions in the middle of the nebula are dust lanes that absorb light and make it difficult to see deeper into the cloud where new stars are forming.

In addition to its stunning visual appearance, the Trifid Nebula is also a site of active star formation. Within the nebula, there are several regions where new stars are being born - known as Bok globules - which are dense clouds of gas and dust that are collapsing under their own gravity.

With this project my focus was on learning and improving my Pixinsight stretching skills, experimenting with more sophisticated tools like arcsinh and masked stretching. I was struggling to keep the stars at bay for whatever reason and when I had them in a more desirable shape and size the contrast within the nebulosity had other plans. Using a combination of different stretching methods I came up with this!

M20 from Calar Alto Observatory (South of Spain).

Messier 20, also known as the Trifid Nebula, is a fascinating astronomical object located in the constellation Sagittarius. The Trifid Nebula gets its name from the Latin word "trifid," which means divided into three lobes or divisions. It is called so because the nebula appears to have three distinct regions separated by dark lanes of dust. These divisions are easily visible in photographs and resemble three intersecting paths or lobes.

It is a region of active star formation. It contains a cluster of young stars known as NGC 6514, which is responsible for illuminating the nebula. These newly formed stars are hot and massive, emitting intense ultraviolet radiation that causes the surrounding gas to glow.

The Trifid Nebula is a composite nebula, meaning it contains different types of nebulae within its boundaries. The pinkish-red regions are emission nebulae, consisting of ionized hydrogen gas that emits light of specific wavelengths. The blue areas are reflection nebulae, where starlight is scattered off dust particles, giving them a blue appearance. Additionally, dark nebulae are visible as intricate, dark lanes caused by dense dust obscuring the background light.

It is relatively close to us, located at a distance of approximately 5,200 light-years from Earth. It has an apparent size of about 28 arcminutes, which corresponds to an actual size of about 21 light-years across.

The Hubble Space Telescope has captured stunning images of the Trifid Nebula, revealing intricate details and structures within the nebula. These observations have provided valuable insights into the processes of star formation and the dynamics of interstellar gas clouds.

Messier 20 was first discovered by the French astronomer Charles Messier on June 5, 1764. Messier included it as the 20th entry in his famous catalog of nebulous objects. His intention in creating the catalog was to identify objects that could potentially be mistaken for comets.

Messier 20, the Trifid Nebula, continues to captivate astronomers and stargazers alike with its remarkable beauty and scientific significance as a site of ongoing star formation.

This picture was captured with a prototype telescope in Calar Alto Observatory in Almeria (Spain).

Title: Moon and Venus clockwork conjunctions !

Explanation: When two objects of the night sky have the same right ascension they are said to be in conjunction. Among the visible conjunctions, those including the crescent moon and Venus are one of the spectacular sights of our night sky. The Moon-Venus conjunction is a result of the positioning of the Moon and Venus in close proximity to each other in the sky from our perspective but in reality they are far apart. From an astronomical point of view, this is caused by the relative orbits of the Earth, Moon, and Venus around the Sun.
This season since it's approach to the Eastern elongation, planet Venus has been in a series of very close conjunctions with the crescent moon each month and resulted in positions surrounding almost every side of the crescent just like a clockwork across the sky.

Story: I had been capturing all these conjunctions every month over the past 6 months (except for March which I couldn't, due to cloudy skies so created a composite to complete the series) and decided to create a collage in a clockwork fashion.

EXIF:
Canon EOS 1300D
Samyang 135mm f/2 lens
Ioptron sky tracker
All images are single exposures of around 25-30 seconds tracked and cropped.
PS 2020 used for creating the collage and labels.

Images capturing location and dates below.

All images taken after sunset at start of astronomical twilight from Lahore and Islamabad, cities of Pakistan.

I consent for my image to be used on APOD in all of it forms.

The Dragon in Cygnus
This is the complex around Sharpless 2-114. This is an extremely faint hydrogen and dust complex not far from some of the more popular nebula in Cygnus. The unique filamentary structure appears like an ancient supernova remnant but none have ever been recorded in this area. Not much is known about this area. Current theory suggest the shapes have formed from both magnetic fields and interstellar wind from nearby hot O and B type stars.

The ringed, warped and isolated galaxy NGC 6015. KG Observatory, Julian CA.

NGC 6015 at 40 million light years distance is an isolated and warped type Sc-r galaxy. Recent studies indicate a discontinuity in the formation of the spiral arms and different rotation rates between the inner and outer arms. There is no indication of bar formation. There is a noticeable tail emanating at the top.

The tiny red objects are likely very distant galaxies.
