IC 1396A is the Elephant's Trunk nebula, located in the constellation Cepheus. The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396, at an estimated distance of about 2,500 light years.
At the heart of the nebula lies the open star cluster Trumpler 37, where several hot, young stars (less than 100,000 years) are thought to be forming. These stars emit copious amounts of hot plasma winds and energetic particles that ionize the gas in the nebula and causing it to glow with the characteristic red light of hydrogen atoms. The winds are also sculpting the nebula creating the central cavity, but also compressing the gas in dense regions and triggering a new generation of protostars, hidden inside the dust.
At the estimated distance of the nebula, the Elephant's Trunk is about 20 light-years long.
Thanks to all for your continuous support and kind comments. I wish to all my Flickr friends a happy and relaxing summer and looking forward for your beautiful photos and stories!

As you can see with a focale of 600mm in both case, moon size is different because moon distance to the earth always change (from 356.000km to 406.000km). Here there is a difference of distance of 7.5%, so that means a difference of size of 7.5% (+/- 100pixels in this case)

Comme vous pouvez le voir avec une focale de 600 mm dans les deux cas, la taille de la lune est différente car la distance de la lune à la terre change toujours (de 356.000km à 406.000km). Ici il y a une différence de distance de 7.5%, donc ça veut dire une différence de taille de 7.5% (+/- 100pixels dans ce cas)

My most recent moonscape featuring the prominent Copernicus, Aristarchus and Gassendi craters.
The image has been shot on January 18 from my backyard in Luxembourg. The seeing conditions were pretty good.
It's a crop out of a 6 pane mosaic. For each pane I stacked 20% of about 2.000 frames.
The saturation is increased by a fair amount in order to highlight the mineral composition of the moon's surface.

The Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and is approximately 2400 light years from Earth.

Story:
Captured in the heart of the Jalapão region, this panoramic nightscape reveals the raw beauty of Brazil’s Cerrado under a pristine Bortle 1 sky. Dominating the scene is the luminous arch of the Milky Way, stretching from one horizon to the other, its core glowing with interstellar dust, emission nebulae, and countless stars. The reddish tones near the galactic center are enhanced by the use of a modified sensor, revealing prominent H-alpha regions like the Lagoon and Trifid Nebulae.
To the right, a striking column of Zodiacal Light rises—sunlight scattered by interplanetary dust—perfectly aligned with the ecliptic. Subtle green and red hues of airglow add a surreal touch to the lower sky, interacting with the warm tones of the dunes and the reflecting waters of the meandering stream. Buriti palms and native vegetation complete the composition, grounding this celestial spectacle in the unique landscape of the Brazilian savanna.
This image is not a blend but a multi-frame panorama, precisely captured to preserve the spatial relationships of both the terrestrial and astronomical elements. A technical and artistic tribute to one of the darkest skies in South America.

The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula located in the constellation Aquarius.
The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture, as well as the "Eye of Sauron".

NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. It is either a lenticular or spiral galaxy.
NGC 3718 has a warped, s-shape. This may be due to gravitational interaction between it and NGC 3729, another spiral galaxy located 150,000 light-years away.

The path of the moon was photographed throughout the night of Sept 18th to the early morning hours of Sept 19, 2021. This was a day before the infamous "full harvest moon" of 2021. A photograph above the corn field was taken near the end of the blue hour and used for the background. Using an intervalometer, the moon was photographed every 15 minutes using a Canon 80D and a Canon 8-15 mm f/4L lens @ 13 mm. (ISO 400, 3.2 sec, f/6.3 was used for each moon exposure)

The Moon, at the time of capture, was at its meridian transit but a little high above the horizon (about 25 deg). At this height, any object is affected by atmospheric absorption. The hue is often warmer and a very high definition is not achieved. Normally all the details are softer than in a zenith capture.
