North America Nebula, 1,700 light-years away.

Sky-Watcher Esprit 80mm, Player One Poseidon M pro camera, Sky-Watcher EQ6Rpro mount. Primaluce Lab Esatto, Arco. Antlia 3nm SHO filters. Shot at the Texas Star Party, April 2025.

Total integration 11hr 20m

this is a picture i've been wanting to shoot for years.

i knew from the photographer's ephemeris that yesterday, april 28th, the full moon would rise very close to poseidon's temple at sounion. i'd been waiting for a month for this day to come, and was thrilled that anthony ayiomamitis was planning a capture as well... so i joined him and his friends across the bay for a shot.

we were almost 2 kilometers away, the sky was clear and it was a bit windy.

anthony was set up ahead of time, already focused with his monster 'scope. as the moon started to appear, these guys started running back and forth with their cameras and telescopes to get a better position.

and i followed!

it's one of the funniest things i've ever seen.

i saw some of the others' shots which were just wonderful... i'll link to them here when i see them online.

EDIT: this by chris kotsiopoulos.

i can't say i'm satisfied with mine -- despite anthony lending me one of his lenses (500mm f/8) and giving me advice, the focal length was too short, as was the exposure. i should've increased the ISO. i used canon's digital photo professional to increase the exposure (i always shoot in RAW), then i reduced noise and cropped slightly to improve the composition. it's not a nice, crisp shot, i know, but i'm still happy that i captured this moment: the moon amidst the columns -- and in the middle, you can see the altar!

i do intend to learn more so as to eventually take one i'm pleased with. i think next month will be another good opportunity.

and i need a telescope!

this image is on the map.

Ic434

IC 434 is an emission nebula visible in the constellation of Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.

This is an H II region that extends south of Alnitak, on the southwestern edge of the large Orion B cloud; it has a very elongated shape in a north-south direction and receives the ionizing wind directly from the star σ Orionis, a bright member of the large Orion OB1 association.

The nebula reaches 70' in length and is easily shown in long exposure photos or CCD images, although its thickness is only a few arc minutes.

The temperature of the region was measured using various methodologies and exploiting various radiation ratios, initially obtaining values ​​between 8000 K and 7600 K;

subsequently this value was reduced to 3360 K and even less depending on the map taken as reference. A study on electronic temperature conducted in 1992 instead provided a value more similar to the previous ones, which is around 6000 K.

Messier 16 – M16

Constelación en que se encuentra: Serpens

Distancia: 7.000 años luz

De SkySafari:

Messier 16 (#M16) es una nebulosa ubicada en la constelación Serpens. Corresponde a una región de formación de nuevas estrellas. En la imagen también se ve el cúmulo NGC 661, descubierto en 1745. M16 fue incluida por Charles Messier en su catálogo en 1764.

En 1995 el telescopio espacial Hubble tomó la imagen más famosa de esta nebulosa, conocida como los Pilares de la creación. Los pilares se ven en el centro de la imagen.

Estudios de 2007 realizados con el telescopio espacial Spitzer han sugerido evidencia de que los pilares fueron destruidos hace unos 6.000 años por la explosión de una supernova. Si se tiene en cuenta que estaban a 7.000 años luz, su nueva forma posterior a la destrucción, solo será visible desde la tierra dentro de un milenio.

NGC 6727

An extremely intriguing area of the night sky. NGC 6727 is a combination of dark, reflection and emission nebula, with designations IC4812, NGC 6726 and NGC6729, along with the globular cluster NGC 6723 in the constellation Corona Australis that is approximately 500 light years distant. The extended field shows several regions of faint Ha-emission as well as several small reflection nebula. Of particular note is the beautiful semi-circular Ha-emission peppered with some faint wisps of reflection nebula (not OIII), excited rather than illuminated by the nearby star and demonstrating quite profoundly that hydrogen is a major constituent of the surrounding dust. Also to be seen is a relatively "large" spiral galaxy at the bottom of the nebula (Designation: PGC-62700, 250.000.00 light years distant). The Region NGC 6727 is actually the tip of a considerably larger dust cloud (4 panel mosaic) extended for quite away beyond the right hand edge of the single image. OIII and SII emissions are particularly present in the bright core of the system. A wonderful target and certainly not the last time I will be paying a visit.

The data was collected by myself using a remote rented system in Australia (Martin Pugh)

NGC 6188 / NGC 6193 / NGC 6164 / NGC 6165

In the heart of the southern skies, nestled within the constellation Ara, approximately 4000 light-year from Earth, lies a celestial story of life and death played out in the glowing embrace of the nebulae NGC 6188 and NGC 6164, illuminated by the brilliant stars of the open cluster NGC 6193. NGC 6188 stretches as a veil of stardust, where newborn stars emerge from towering pillars of dark gas, sculpted by the intense winds of their luminous companions in NGC 6193, into figures commonly known as the “Fighting Dragons”. Together the “Dragons” overlook the symmetrical lobes of the “Dragon’s Eye“, NGC 6164 and NGC 6165, which surround the massive O-Type star HD 148937. This star, in an advanced stage of its life has ejected material, that it now illuminates, with a further delicate outer viel of Oxygen (blue) being clearly visible. Together the region shows many aspects of the Vita Cealestis.

Here's a pretty field of galaxies. In the middle is M100, about 166,000 light-years in diameter. Yes, going at the speed of light, it would take you 166,000 years to cross it. And, the light that came from that galaxy, which then hit my camera's sensor last week left that galaxy 55 million years ago.

M1 The Crab Nebula in Sulphur Hydrogen Oxygen and Helium. Imaged remotely from Spain with the 16in Dall-Kirham and Player One Poseidon M-pro . Exposures were 60x 120 in S2, 50x 120s in Ha, 50x120s in O3 and 50x 300s in He2

I really like the addition of the Helium, it brings something very different compared to the "usual" SHO palette that we are so used to with M1.

Although all of the elements show very different structure to each other the He2 seems to have a more diffused look about it.

Avec Julien Dufour et Christophe Vergnes

Astrobin : astrob.in/452ptn/0/

Situé au cœur de la constellation du cygne ce champ est d’une grande richesse en structures et objets.

On peut y observer des nébuleuses brillantes comme LBN223, plusieurs nébuleuses sombres comme B434, l’amas ouvert ic1311 et même la petite nébuleuse planétaire Patchick6.

La très forte présence de signal Ha & Oiii donne à ce champ une teinte magenta assez inhabituelle.

L’image, réalisée sur 2 mois, compte environ 23h d’intégration.

The Crab Nebula (M1) has a pulsar in its center that is at the origin of these filamentary structures. With its sweet name PSR B0531+21, the Crab Pulsar has a magnitude of 16 and is thus visible on long exposure times.

In addition, it has a frequency of about 34ms with two distinct pulsations in this period. It is therefore possible to detect its pulsations via the Lucky Imaging method thanks to shorter exposure times.

But here a first challenge appears. The pulsar is visually close to another star, which implies that it is necessary not only to resolve it temporarily but also spatially. In other words, very short exposure times and a large diameter were required.

One of the drawbacks of this technique was that it was necessary to find at least two stars clearly visible on the raw images in the field in order to perform the alignment and therefore all the processing. I therefore had to take images with a fairly large size in order to find two stars visible on 5ms exposures, generating about 2TB of data to process.

Then comes the longest part which consists in sorting all the images according to their position in the pulsar period in order to stack them together. I wrote a small python script to sort the 471000 images based on their timestamp. It took about 1 month of non-stop process for sorting, aligning and stacking.

This was by far the most complex and longest project I have done so far and I am proud to present the following animations.

On each of the stacks, we can barely see the nebulosity, so I mixed the original starless with a Halpha starless made with a 150/750 telescope for aesthetics (50/50).

Collaboration between myself and Ahmed Wegdan. Inspired by Tim Schaeffer and the Deep Sky Collective's dedication to capturing elusive celestial objects, and their collaborative approach and attention to detail that have pushed the boundaries of what amateur astronomers can achieve. Fueled by inspiration and a passion for astronomy we set our goals on one of the harder and lesser imaged known celestial objects; Sh2-155 was a perfect candidate.

Armed with a rich Egyptian astronomical heritage, Pyramids Obelisks, and Thousands of camels I embarked on a journey into the depth of time ..... uhm wait what? ... darn you Chat GPT, bad AI..

The overall plan was for Ahmed to image in NB from Bortle 4-5 while I capture sort of a broadband-ish data using the Antlia-Quad filter from my home.

We quickly revised the plan and decided that I should capture my data using a dual narrowband filter instead.

Our rigs were perfectly matched, His fra600 with a reducer and a 2600mc pro and my Fra400 with a Poseidon M have almost identical Image scales and FOV, which made stacking much easier.

We live to learn, and learn we did, there is always something new to try, or some way you can improve and producing this image can be easily described as a learning experience.

The amount of data that we threw away, would otherwise make a decent image, but we were not going for decent, we were aiming for great. We each went through each sub multiple times and stacked multiple times over and over until we were finally satisfied that the data was improving with every new addition.

We must have come up with at least 29 drafts, using several techniques. Alaas we, had to produce a final version, so we agreed to combine multiple reversions together to get the best of ALL worlds. I think the result will speak for itself. Our final image, characterized by its exceptional detail and overall aesthetic, is a testament to our efforts.

The data was acquired over the course of 41 days from 2 different locations. A Whopping total of 170 hours. We then microscopically discarded a ton of data, to make sure we have the best of the best, at the end the final integration time was about 84 hours, composed of:

30h 40m dual narrowband (Ha/OIII)

24h 45m of OIII

12h 20m of SII

13h 50m of Ha

3h 4m of Luminance

1h 48m of Red

1h of Blue

1h of Green

We hope this image not only showcases the beauty of SH2-155 but also reflects our passion and dedication that was poured into its creation.

The Cats Eye Nebula in RGB Ha and O3. Imaged remotely from Spain with the 16in Dall-Kirkham and the Player One Poseidon M-pro...I am really liking this new camera so much cleaner than the previous ZWO with far superior cooling.

Exposure times were 60x 60s in each RGB filters, 240x 60s each in O3 and H-alpha.

Imaged at 1x1 then software binned to 2x2 Processed in Pixinsight and Photoshop.

Thanks for looking

Peter Shah

Additional Info

Anyone who has imaged this one knows how difficult it is to pull out the core detail. Looking the stunning high res-HST image was very useful for reference making it easier to see similarities in the core structure.... I wanted to see if I was able to pull out those beautiful spokes, but honestly I think I was kidding myself to think I could do it with a modest 16in ground based scope. However If I squint my eyes to the point where they are virtually closed and believe like a kid at Christmas sometimes I think there is evidence of them being there!!!

The concentric rings or shells and the knotted jets however are a different story they are quite clearly shown, more visible in the O3 data, virtually nothing in the Ha and only a hint in the RGB. I did take some Helium data but it really didn't bring much to the party so I excluded it from the final image. You have to roll the dice once in a while!
