Among the most photographed deep sky object - M16 - or the mighty Eagle Nebula.

Located in the constellation Serpens, Messier 16 is an open cluster that stands out against a diffuse nebula background. If the stars of the cluster are visually accessible with a telescope, it is another story for the red draperies of the nebula which require long photo exposure times.

The color palette of this rendering was obtained by blending together two narrowband filters : H-alphy & Oiii. Processing this marvel was smooth. I very much liked it.

Clear skies,

Here is Comet E3 ZTF as seen on Jan 22, 2023 from dark sky of Death Valley, CA.
That was the week when astronomers and astrophotographers started noticing the #antitail.
Comet C/2022 Z3 ETF has stunning green head while tail is not.The secret to the green glow is in diatomic Carbon (C2) according to several research studies done around the world. Comets are made up of frozen gases, rocks and dust mainly the leftover remains from the formation of the solar system about 4.6 billion years ago. As comet nears the Sun, it heats up, ice turns into gas creating an atmosphere called Coma. Mainly carbon based molecules being bombarded by ultraviolet light from sun creates highly unstable and excited particle C2. Those particles revert to ground state by emitting a photon. For C2, that is of green color.

Pleiones Daughters by Andre Vilhena, no Flickr

Pleiones Daughters

When Atlas was punished to bear the heavens on his shoulders, his seven daughters with Pleione - Asterope, Electra, Merope, Maia, Celaeno, Taygeta, and Alcyone – started to be pursued by the hunter Orion, who had fell in love with them and their mother. In pity of their suffering, Zeus first turned them into doves and then into stars, to protect them from the Orion’s advances who, it is said, still pursues them across the sky.
Known from, at least, the Bronze Age, the Pleiades star cluster an hallmark and leitmotiv for mythologies across several civilizations and they were/are also known as Soraya (old Persia) or Subaru (Japan).
The Pleiades is an open cluster with about 1,000 stars at about 440 light years but only the brightest are visible at naked eye, even in light polluted skies; but in a dark sky and viewed through binoculars it is a truly amazing sight. They will be gravitationally bound for another 250 million and by then it will disperse in Orion’s constellation.

The Veil Nebula in Cygnus, with its intricate structures, is one of astrophotographer's preferred nebulas in the night sky and is the result of a supernova which happened between 10,000 or 20,000 years ago.

Sagittarius Cloud

Despite being in Messier catalog, the Sagittarius Star Cloud - Messier 24, is an often overlooked target for astrophotographers. However, it is a beautiful concentration of stars at about 10,000 light years from us, located in the Sagittarius arm of our galaxy. During the shooting of this photo, I had the chance of observing it with a regular binocular and it is amazing the sheer amount of stars that can be seen.

I am pleased to share with you my last processing : SH2-308 - commonly dubbed as the Dolphin-Head Nebula by astrophotographers - a HII region located near the center of the constellation Canis Major. It is thought to have formed about 70,000 years ago and the Nebula is bubble-like and surrounds a Wolf–Rayet star named EZ Canis Majoris

South Pole Shining
South Pole Shining by Tom Glenn, on Flickr

This image shows the southern limb of the Moon, captured approximately 12 hours before the moment of the Full Moon (Snow Moon). The image was captured last weekend on February 4, 2023.

The rays of Tycho are on full display, but a key point of interest in the image is that due to an advantageous libration in latitude, we are looking over the lunar South Pole while it is favorably illuminated. Interestingly, all of the proposed landing sites for the Artemis III mission are visible in the image, which is rare for an Earthbound image due to difficulties with perspective and illumination. Please see this cropped and labeled image for a few key landmarks in the region, including the South Pole itself on the rim of Shackleton. By chance, the illumination pattern in my image is almost identical (albeit foreshortened) to that observed in the rendering provided in the NASA press release.

It is not as bright as the 2020 comet, but it shows well in all fields of view. Binocular photos are taken of it, but it looks good even in a larger field of view.

The shot was taken with a 135mm telephoto lens before the last dawn of January, when it was still completely dark.

UGC 2838
Through the dust of Pleiades star cluster, is a faint galaxy. UGC 2838 is 316 million lighyears away from the Earth. I was pleasantly surprised that I was able to capture it. The imaging conditions were very challenging. Wind gusts and dust were making it very hard to have good guiding.

Comet C/2022 E3 ZTF and U2 ATLAS imaged on Feb 6th between 9:45 and 11:30 EST. Comet E3 ZTF is a stack of 85 one-minute exposures. Comet U2 ATLAS is only 10 mins of exposure to minimize blurring. I used a RASA8 telescope at f/2 with a Zwo ASI2600MC camera to capture the image. I was guiding on the comet using a Zwo AM5 mount.

A 62-hour widefield image of Orion by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/a-62-hou ... -of-orion/

The dark Horsehead Nebula and the glowing Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of the night sky’s most recognizable constellations, they appear in opposite corners of the above stunning mosaic. The familiar Horsehead nebula appears as a dark cloud, a small silhouette notched against the long red glow at the lower left. Alnitak is the easternmost star in Orion’s belt and is seen as the brightest star to the left of the Horsehead. Below Alnitak is the Flame Nebula, with clouds of bright emission and dramatic dark dust lanes. The magnificent emission region, the Orion Nebula (aka M42), lies at the upper right. Immediately to its left is a prominent reflection nebula sometimes called the Running Man. Pervasive tendrils of glowing hydrogen gas are easily traced throughout the region.

This is easily one of my most ambitious astrophotography projects to date. Given that I’m fairly limited by my dslr in terms of imaging very dim objects, I decided to dump as much time on Orion as possible to see how much dust and gas in the region I could reveal. I was struck by how much wispy H-alpha gas didn’t line up exactly with the dust in the region – it was very cool to see the differences in ionized and non-ionized gas.

LST-1 Telescope seaxrching the night sky | 135mm pano

LST-1 Telescope searching the night sky [135mm pano] by Martin Giraud

Hello ! Here is my first 135mm pano, you can see the LST-1 telescope (next to the MAGIC ones for those who know) and the GrandTeCan behind

I used to do 50mm pano but this time I wanted to try something bigger and it was not so easy. Indeed at a 135mm focale it’s quite more difficult to align your tiles correctly and mostly it’s so much longer ! It’s a 20 tiles panorama where each tile is a stack or 3 or 4 pictures a 30 seconds interval, I shot more pics but not was good enough to be in the final pano. The final pic represents 32 minutes of exposition, it sounds not so much but it took me at least 2 or 3h to shoot it.

Another difficulty here is the postprod. My camera is astromodified (it captures more red light than a normal one) and what I didn’t know is if I take pictures with the live view activated it gives huge red stains on the picture. It was a nightmare to remove those artifacts… but a good lesson learnt !

I shot this picture during an astrophotography trip in the island of La Palma in Canarias. La Palma island in Canary is a very well known location by the astrophotographers. Indeed the sky conditions are outstanding enough that it’s considered as one of the best spots of the northern hemisphere for astronomy. It’s a Volcanic island that hosts several international telescopes regrouped into a park called Roque de los Muchachos that is located on the top of the caldeira at 2400m.

If you have any feedback or suggestions I will be happy to read them

Sky : 16 tiles, each is 3 pics stacked : 30 sec | ISO-3200 | f2.8
Foreground : 4 tiles, each is 4 pics stacked : 30 sec | ISO-5000 | f2.8

The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.

The nebula has been noted to be having a shape reminiscent of a human skull, and is sometimes referred to as the "Skull Nebula."
