I had some concerns with the weather but the skies did clear and which allowed to capture the ISS transiting the Sun while being at a range of 551 km, thus allowing for good image scale as well.

Further details at https://www.perseus.gr/Astro-Sat-Trans-2023-10-01.htm.

The Elephant's Trunk Nebula, part of the larger IC1396 complex located in the constellation Cepheus roughly 2,400 light years away.

Mosaic of M8 and M20.

- The Messier 8 (NGC 6523) or Lagoon Nebula is the star of the scene, one of the best star-forming regions in the sky, and is faintly visible to the naked eye. It is a gigantic glowing cloud of interstellar gas, divided by a dark band of dust, containing a cluster of young stars (NGC 6530) that have formed from it. This attractive Messier object lies at a distance of approximately 4500 light-years and lies at the heart of the Sagittarius-Carina spiral arm of our galaxy.

- The Trifid Nebula, located above and named for its three-lobed appearance, is another of the most famous objects in the sky and lies about 2° northwest of M8. This object is an unusual combination of an open star cluster, an emission nebula, a reflection nebula, and a dark nebula that divides the emission nebula into three parts. M20 is estimated to be about 5200 light-years away, at the other end of the same nebulosity complex as M8. Star formation is no longer occurring in the vicinity of the central cluster, because its intense radiation has expelled the gas and dust from which new stars form.

- The mosaic I am sending you is composed of 2 images taken during 12 nights this summer from my backyard in a city with Bortle 6. There have been a total of 60 shots of 300" for each panel, so each panel has 5 hours of integration. I hope you like it!

This wide field view of part of Sagittarius, shows the Lagoon nebula (M8) and Trifid Nebula (M20) as erupting ionization areas embedded in a rich field of molecular clouds. There are many other seldom imaged interesting structures within the surrounding area such as filaments and other areas of nebulosity partially obscured by dust clouds.It's thought that despite the apparent promimity, M8 and M20 arise from different molecular clouds
M8 is about 5,000 light-years away, and roughly 110 x 50 light-years in size , it's huge and the second brightest nebula that you can see with the naked eye. The Lagoon Nebula is first an emmision nebula, composed primarily of hydrogen. The blue glow within is reflection nebulosity from the many young energetic stars within iradiating the gas and particularly the massive star Herschel 36. It’s also a place where new stars are born. The open star cluster– NGC 6530 – made of hot, blue stars just a few million years old lies in this region. In addition to these young stars, there are also many dark Bok globules (dark nebulae) of condensing gas and dust. These are precursors to becoming proptostars, and ultimately fully-fledged stars like those already formed nearby.
M20 is similar in that it is both an emmision and reflection nebula, and has energetic massive stars within. It's distance has proved difficult to measure and estimates range from 4.3 to 9K LY
IC4685 ( shown to the right upper in this image) is an often overlooked reflection nebula and perepheral to it are even more interesting such objects IC 1274 and IC468, this stuff should really have a name

Double Sun Transit
During a transit of the ISS on the Sun at a very low height above the horizon (8.5°), I was also able to capture in the same footage, after about 12s of the ISS exit, a second transit :a Boeing 737-800 landing at the nearby Milan Malpensa airport.
In the same image there is an object at 2.6 km, one at 1,586 km and one at 150,000,000 km.

French belfry in front of the moon
https://www.flickr.com/photos/julienlooten/

The Sun of the Golden Lion, crowning the summit of the Belfry of Arras (France), meets the Moon...

First and foremost, it's essential to stress that this image is entirely authentic, free from any manipulation, trickery or intervention by artificial intelligence.

This photo has been on my mind since I started photography... I'm not going to hide it, it was a challenge, even a nightmare.

I shot several moonrises over emblematic monuments in the Hauts-de-France region (northern France), such as Laon Cathedral and Mont Saint Eloi. What these monuments had in common was their elevated position, making them visible from afar. The Arras Belfry, on the other hand, is nestled in a bowl, surrounded by buildings and vegetation, making it almost invisible from a distance. In the Middle Ages, the belfry had military functions: the bell rang the opening and closing of the town gates and the building was used as a prison.

Every full moon was an opportunity for me to search desperately for the perfect vantage point to capture the Belfry with the moon rising perfectly behind it. I'll spare you the hours spent calculating the various astronomical positions (time, altitude, orientation, phase of the moon, etc.), the miles travelled along barely passable paths in search of the perfect angle, as well as the vagaries of the weather (clouds on the horizon, humidity, etc.)... real challenges to overcome…

Finally, after many strenuous attempts, the long-awaited moment arrived. About 4 km from the Belfry, between Achicourt and Dainville, the Moon, illuminated at 83%, rose precisely at 9.05pm (03/10/2023), standing perfectly behind the Belfry. At this crucial moment, I had no room for error... I had my eyes riveted both on the moon (a magnificent sight to the naked eye) and on the camera mounted on the telescope...

The lion is the emblem of the town of Arras, and at the top of the belfry a golden lion was installed at the request of Louis XIV (the great sun king), hence the sun in the lion's hand. This coincides perfectly with the moon. Listed as a UNESCO World Heritage Site, the belfry was voted France's favourite monument in 2015.

I hope you like the result.

Story

Orion And aurora season is starting , september this is the best time of the year to capture them both in one frame i used a Filter for Ha and Regular Clear Filter For RGB then Blend both integration to a single image with out moving the tripod. to capture both of them in the same time is a challenging task,
The goal was to capture orion and aurora in the same time
this is the second year i'm guiding astrophotography tour in iceland chasing orion and aurora to capture the northern light wonder with celestial deep space objects near solar maximum period to get an amazing display of celestial phenomena of orion Rising next to Aurora Dancing Lights

I've been chasing this photo for over a decade. I was fortunate enough to make it a reality yesterday! The shot was taken from Patroklos, a small historically significant, uninhabited island located to the west of the Temple.
There was no transport available and the private boats were unavailable after sunset so I decided to get there by kayak boat. After an hour of paddling and one more hour of climbing the rough terrain, I was in place for the shot.
5.300 meters away, I could barely see the Temple. At 19:25 local time, the Moon started emerging from behind the hill and slowly aligning with the Temple. What a moment! As I was shouting out of excitement, I saw a fishing boat in short range. I believe they were looking at the same spectacle or perhaps they were looking at me wondering what I was doing in the middle of nowhere!

According to my astronomy app, the Moon's altitude in the first photo was 1/3 of a degree.
The infamous olive tree next to the Temple is not present in the photo. Don't worry. It's still there! It is just not visible from this angle.

Hi friends. Here is my masterpiece. This might be the best image I have ever taken and might be one of the most detailed images I have ever seen of this galaxy. It has 10 times the data of my previous image of this galaxy. In the full image, you can see hundreds of nebulae, countless globular clusters, and even individual stars in the Andromeda Galaxy. The best 28 hours of data was selected to create this image. I was using an 8" f3.9 reflector and an ASI294MM in Bin 1 mode to get this image. I used intensive dithering and drizzle X2 (after considerable testing compared to not drizzling). Full image is 183 megapixels and shows unbelievable detail. Very happy with how it turned out.

I used Astronomik LRGBHa filters and a Skywatcher EQ6R mount.

The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective.

The Moon keeps one hemisphere of itself facing the Earth, due to tidal locking. This simple picture is only approximately true: over time, slightly more than half (about 59% in total) of the Moon's surface is seen from Earth due to libration.

Lunar libration arises from three changes in perspective due to: the non-circular and inclined orbit, called optical libration; the finite size of the Earth, called parallax; and the orientation of the Moon in space, called physical libration. It permits an observer to see slightly different hemispheres of the surface at different times.

The Helix Nebula, NGC 7293 or God's Eye Nebula is a planetary nebula in the constellation Aquarius, about 680 light years away. It is one of the planetary nebulae closest to Earth and was discovered by Karl Ludwig Harding before 1824. Its appearance is very similar to the Ring Nebula (M57) and its physical characteristics are similar to those of the Dumbbell Nebula (M27)

This nebula is an example of a planetary nebula formed by a Sun-like star in the final stages of its life. The gases expelled by the star appear from our perspective as if we were seeing a propeller from above, which is where its name comes from. The remaining star is a white dwarf. The age of the nebula, based on its expansion rate, is estimated at approximately 10,600 years.
