Here is my last submission for APOD.

The Crescent Nebula (NGC 6888, Caldwell 27, Sh2-1105) is an emission nebula in the Cygnus, about 5000 light-years away from Earth.

This Nebula composed with Alpha-Hydrogen and Oxygen (the blue bubble around the Nebula) is born from a central Wolf-Rayet star that pushes the hydrogen and oxygen atoms outward.
The WR star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years.

In the bottom left there is a Planetary Nebula called The Soap Bubble Nebula.
This star is destined to become a slowly cooling white dwarf like the Sun.

I wanted to get the natural colors by mixing Ha/Oiii and RVB datas and give the best "real render" of this sky area.

Pink Moon

Post by ChrisKotsiopoulos » Sun Apr 17, 2022 12:07 am

It was so beautiful to watch that I nearly missed the swan that was slowly passing by at the right time. The Moon's pink colour, suitable for the occasion (as this is the Pink Moon) was unintentional.

A french church haloed by the Milky Way
https://www.flickr.com/photos/julienlooten/
Copyright: Julien Looten The bulb (or « center ») of the Milky Way is now visible in the northern hemisphere, around 4am in France. To make this photograph, I had to be brave and patient: wake up at 3:00 am, more than an hour of driving in the dark, and 3 hours of session.... I had to be motivated, and be sure of the weather...

But the objective is fulfilled, the conditions were perfect (little artificial light, and a very pure sky). The Sainte-Presentine church in Frontenac (Gironde) is a place full of history (one hour from Bordeaux). The site was occupied by the Romans in ancient times, and a church was built in the 12th century. A Templar tomb is located here. Lost in the middle of the French vineyards, this place is a perfect spot for the astrophotography and history enthusiast.

In this photograph, the church is surrounded by a frosted meadow (-4.5°C), and appears to be haloed by the arch of the Milky Way. On the left, we can see, the constellation Cassiopeia - In the centre the constellation Cygnus and many red nebulae - And on the right, the bulge of our galaxy and Rho Ophiuchi.

This image is a panorama of 16 photographs taken with a Samyang 14mm and a Canon 6d Astrodon (modified for astrophotography). It was taken on 3 April 2022. Thank you in advance.

Cosmic Fireworks | Coma Galaxy Cluster

Composite image created by Garrick Walles (c)

ImageAnnotated | Coma Galaxy Cluster Composite by MessierX, on Flickr

ImageCosmic Fireworks | Coma Galaxy Cluster Composite by MessierX, on Flickr


Also known as Abell 1656, the Coma cluster of galaxies lies more than 330 million light-years away and is dominated by the two major giant elliptic galaxies NGC4874 and NGC4889. Galaxy clusters such as these are the largest structures in the Universe held together by gravity.

The Coma cluster is large and spans more than 2 degrees in the sky. This corresponds to an angular size of four full moons. The motivation for this project was to create a wide-field view of the Coma cluster that incorporated X-ray data from the Chandra Observatory to give a better perspective of its true size and the interactions that take place within the central region. This image spans 1.71 deg by 1.24 deg and is centred on the two main elliptical galaxies. The X-ray emission region (calculated from the plate-solved image) spans about 21arcmin (2 million light-years).

This composite wide-field of view image was created using my data (wide field, 71mm William Optics GT APO, 400mm focal length, London, UK) together with image data from the Chandra X-Ray Observatory, the XMM-Newton (ESA) the Sloan Digital Survey and the Hubble Space Telescope (HST)1,2. The three main components of this image consist of hot gas (responsible for the X-Ray emission), individual galaxies and dark matter.

The Chandra X-Ray data shown in pink represent the newly discovered long arms of hot gas discovered within the Coma cluster3,4. The extended long arm features shown span at least 0.5 million light-years and has provided some insight into how the Coma cluster has grown through a series of accretions and mergers. It is estimated that these arms are about 300 million years old.

The entire structure is permeated by hot gas and these regions are shown in the blue and red hues in the image. These regions of hot gas were captured by XMM Newton's European Photo Imaging Camera (EPIC)5,6,7.

D100
Incorporated into this image is the long gas tail of the spiral galaxy D1009. The image is very faint due to the large field of view, The image insert shows where D100 has been inserted into the main image. The current model indicates that this Hα tail is a result of Ram Pressure stripping as D100 moves through the medium of hot gas within the galaxy cluster. The narrowness of the tail has been attributed to the influence of magnetic fields. It is an interesting exercise to imagine this tail being extended further to the right in the image insert.

Triptych : full moonrise behind the ruins of the abbey of Mont-Saint-Eloi (North of France).
https://www.flickr.com/photos/julienlooten/
Copyright: Julien Looten
This photograph is guaranteed without special effects/editing. I prefer to mention it, unfortunately, we see more and more of it, and it tends to discredit those who never do it. This photo, or rather these 3 photos, required a lot of preparation and precision. I spent several hours looking for a place (next to Arras, in Pas-de-Calais) that I could see from afar, and oriented East/South-East. I ended up choosing the emblematic ruins of Mont-Saint-Eloi.

The challenge was for the Moon to rise right behind the monument... Not easy, even with the calculation software we have today. I arrived on site 2 hours before moonrise, the challenge being to specify the position of the camera according to the orientation, inclination and altitude of the site.

To take these photos, I used a 1000 mm focal length telescope, and a 6d canon. I was about 3.5 km away from the monument. I had no right to be a few degrees wrong otherwise I would have had to put away all the equipment, redo 300-400m by car, and reinstall everything…. In the end, I had a margin of error of about 30-50 meters, so I carried the telescope by hand to move it….. It was sporty…

As the Moon rose (it rises very quickly), I moved the telescope a few meters to stay in line, and to ensure that the Moon remained directly behind the monument. This is why the photos are not strictly the same. The moon was very bright, and I had to do HDR, that is to say, I took 3 photos with different exposures to avoid overexposures and underexposures.
Thank you in advance! :)

Panoramic photograph showing the show of colors in the skies of Iceland at dawn on 03/31/22.
The aurora borealis forecast websites and apps indicated KP 7 index since the beginning of the night of 03/30/22, which in fact did not occur. In the beginning of the night the aurora borealis was very weak and only on the horizon line, which ended up discouraging some people in my group, who returned to the hotel. I and 3 other students were firm and confident that the predicted show would happen sometime in the morning. At around 3 am, suddenly, the sky exploded in shades of green, red, violet, blue... The long-awaited spectacle of the northern lights finally took place. Unfortunately, at this point we were in a generic area, with no interesting subjects to compose the images. That's why I made this image composed of two panoramics taken at different times, with a few days of difference between them.
The foreground was taken at night in Skógafoss, Iceland.

The Firefall event in Yosemite Valley each February has become quite popular, often drawing large crowds to witness Horsetail Fall resembling a stream of lava at sunset. People will be heard cheering and shouting as they view such a beautiful spectacle. Less commonly, this event can also occur in October if there is water in the falls as the sun passes through the same azimuth. Much less known is that a similar phenomenon can occur when a full or near full moon passes through that same azimuth as the sun. This is a picture I took of the moonlit Firefall on 15 April 2022 at 4:43am. You can see the moon on the left of the frame in the trees. My friend and I did give a few cheers, it was such an emotional experience. It was beautiful, and clearly visible to the naked eye, despite the clouds. I think we were the only ones there.

Dendera Temple Stellar Alignment
Hathor Temple at Denderah (26.14 N, 32.68 E )
The Hathor temple or denderah temple is an amazing temple , it is considered to be a complete temple because it contains a whole ancient Egyptian knowledge until the Era of the building circa 54 BC by Greco-Roman empires, also it contains astronomical and astrological signs and included the famous Denderah zodiac, which is now in the Louvre museum in Paris.

The main axis of The temple is on an azimuth of 18º 7’ , the alignment was to the Ursa Major stars. the star Alkaid (eta UMa) the tail of Ursa major disappearing briefly at its lowest descent before re-appearing again, around 54 BC (the date of building ) this reappearance would have been very close to 18 degrees and therefore this is the most likely orientation for the temple.

Note that at the time of the building Polaris wasn’t the celestial pole Star.the celestial pole was a point in the middle distance between polaris and k Draconis stars .

I collected the data of the temple 4 years ago (2018) and reprocess it with old and updated data for the sky .

In this photo we try to catch the alignment of Ursa Major with the main axis of the temple along the Eastern wall of the temple which oriented to the Ursa Major constellation Rising at 18 Degrees at the time of the building but it shifted to be around 35 Degrees nowadays.

Settings : (Blend )
Temple : 1/4 Sec, f8, ISO 800, @18mm
Sky (Big dipper ):25 sec, Iso 1600, f2.8 @14 mm



To the rear of the Hathor temple is a small temple dedicated to Isis. This is aligned to the rising of Sirius at the time of the temple’s foundation.
So the second photo is for the front (facade) of the temple (Dendera) north wall with the southeast sky where the Sirius is rising and Orion is over the temple .

Settings : (Blend )
Temple : 1/4 Sec, f5.6, ISO 400, @18mm
Sky (Orion and Sirius ):25 sec, Iso 1600, f2.8 @14 mm

To take this photo you need to enter the temple after working hours so needs permissions and special opening , it may costs around 1000 $ (but it was for free for the groups who attend a conference there )

Here is the combination of the two photos for the front with Orion and siruis and eastern wall oriented to Ursa Major :

Hyades

Hyades - one of the largest open clusters in our sky, creating a characteristic pattern with the guest star Aldebaran. The whole thing is slightly obscured by dust clouds in Taurus, which, by scattering the light of the surrounding stars, make up a fantastic composition, big enough to become the subject of the wide filed frame.
Effect of last year's autumn trip to the Bieszczady Mountains (eastern Carpathans / Poland). The whole thing was captured with a 135mm Samyang and a modified Nikon D610.

Airplane flying past active sunspot complex AR2993-94

While doing lucky-imaging of the Sun in white light an airplane happened to be perfectly placed close to the active sunspot complex during a few milliseconds which was captured in one of my sequences of 3000 images. This is a selected frame of that exact moment, which also happened to have really good seeing.

Crossing Geminids

🌍 What an hard work. It's a 360° pano of Geminids meteor shower during night peak of 13-14 December. My D850 camera broken during the meteor shots, leaving me alone and freezing during the night, with this amazing work suspended. Here you can see the few meteors caught.
It's a composite, but stars, meteors and foreground were scientifically respected using dedicated software.
Sky's and foreground's panos was shoot with my new Nikon Z7II.
The shot has a huge resolution, like 2,50*1,10 meters ca.
Hope you like understanding sacrifice and time wasted.
Thanks to Federica for my selfie shot.
