Another project I've been working on, this one is part of the Orion complex, including the Orion, Running Man, Horse head, and Flame nebulae. These things have been extremely fun to put together and as I said with the last one, I love the context it gives when compared to a terrestrial objects. This is all shot at 300mm. Foreground is obviously shot separately from the sky.

The Iris Nebula is a bright reflection nebula in the constellation Cepheus. It resides about 1,300 light-years away from earth and is six light-years across. Technical Info:

The Butterfly nebula (IC1318) is located in the constellation of Cygnus. The whole region is huge... Here you can only see IC1318b (upper area of nebulosity) and IC1318c (the lower area). IC1318b and c constitute a single giant HII cloud bisected by a thick obscuring dust lane known as LDN 889 which is shown in the middle of the frame.

The bright star to the top right is a class F8 star known as Sadr or Gamma Cygni. Its true location is only 750 light years away and not related to the nebulosity which is much more distant at 5000 light years.

This is a 6 pane mono mosaic. It has been stitched together using Astro Pixel Processor, whch created a seamless mosaic.

Sh2-155 was first noted as a galactic emission nebula in 1959 in the extended second edition of the Sharpless catalogue.

The name "Cave Nebula" was coined for this object by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth.

Sh2-155 is a diffuse nebula in the constellation Cepheus, approximately 2,400 light-years away from Earth.

IC 443 also known as the Jellyfish Nebula is a supernova remnant (SNR) in the constellation of Gemini. Its distance is approximately 5,000 light years from Earth and a diameter of 70 light years. This image has been processed in the style of the Hubble pallete using two narrow band 3nm filters of Ha and Oiii. This helps to separate the two gasses from each other.

I wasn't quite happy with how the original version of this image turned out, so I decided to start all over with it using a new tool called BlurXTerminator, which works to deconvolve astro images using AI that has been fed data from the Hubble and James Webb telescopes for reference models (this is super interesting because these telescopes shoot from outside our atmosphere and therefore have a clearer view of the stars without the distortions of our atmosphere - among other things) - it's crazy such a thing exists. Anyway, I also processed the image using a Hubble palette, instead of the Ha / Oiii palette, which results in a more pleasing coloration (in my opinion). Anyway, here's the new version!

This is the Elephant Trunk Nebula setting behind Scott mountain here in East Tennessee. The scene is shot entirely at 300mm and is astronomically accurate.

I was starting to do the Witches head but the camera would not focus not matter what I did. My thought was where the stars too Faint. so I turned to Orion with it big bright star.

I did get focus but it turned out the program kept asking me to increase the step size . It turned out it was the very opposite I had to make the steps smaller to the perfect curve.

I had planned to do this as a one shot for both which i still will be doing Plus a 50mm shot of the whole area and the Huge Bernard's Loop of the Whole Orion Area.

This is 148 shot 2 min long all night long then the next night I had to take shorter shots 60 sec , 30sec and 15 sec to over come the blown out core of Orion.

☄️ La comète ZTF au 135mm !

.

🙏 J’ai eu la chance de pouvoir la photographier alors que la Lune n’était pas encore trop forte et lorsqu’elle était proche de sa luminosité maximale, le 29 Janvier 2023. Après avoir parcouru 200km pour trouver une météo plus favorable, j’ai pu poser 2 setups ici, dans l’Aisne, et imager environ 4 heures. Une nuit très rude à rester éveiller jusqu’à 5h du matin par -5 °C.

.

🌠 On peut remarquer très aisément les 3 différentes queues de la comète : la queue de gaz ionisée est la plus longue et la plus détaillée ici. Elle parcourt plusieurs dizaines de millions de kilomètres de long et recouvre près des 2/3 de mon capteur full frame ! La deuxième, plus diffuse, se situe sur le même plan que la première. Elle contient énormément de poussières qui s'échappent du corps de la comète. On la nomme souvent la “chevelure”. Enfin, la troisième, souvent nommée l’”anti-queue”, est opposée aux 2 autres et permet de connaître le direction dans laquelle la comète file. C’est également un résidu de poussière que la comète a laissé derrière elle. La couleur verte qui émane du cœur de la comète est dûe aux interactions chimiques qui se passent entre le Soleil et elle. La couleur verte à proprement dit, n’existe nulle part ailleurs dans l’univers à part aux travers du noyau des comètes.

.

Photographier une comète pendant plusieurs heures est un vrai défi car elle bouge très vite, vous n’avez donc pas droit à l’erreur. L’image que je vous présente ici contient donc quelques défauts car le “dithering” est presque impossible ce qui induit du bruit numérique. Je suis très content d’avoir pu obtenir de tels détails sur cette comète, c’est très rare de voir la queue aussi développée au 135mm ! Et quelle ne fût pas ma surprise en découvrant sur une image, une étoile filante passant juste à côté de la comète ! Une chance inouïe d’avoir pu capturer ça, mettant en perspective un petit gravillon passant à quelques dizaines de kilomètres au-dessus du sol et une comète à des dizaines de millions de kilomètres de nous..

Explanation: At the down right, large spiral galaxy NGC 1055 joins spiral Messier 77 in this sharp cosmic view toward the aquatic constellation Cetus. The narrowed, dusty appearance of edge-on spiral NGC 1055 contrasts nicely with the face-on view of M77's bright nucleus and spiral arms. Both over 100,000 light-years across, the pair are dominant members of a small galaxy group about 60 million light-years away. At that estimated distance, M77 is one of the most remote objects in Charles Messier's catalog and is separated from fellow island universe NGC 1055 by at least 500,000 light-years. The field of view is about the size of the full Moon on the sky and includes colorful foreground Milky Way stars (with diffraction spikes) along with more distant background galaxies.

Some weeks ago I published a “widefield” of the Andromeda Galaxy but then decided to take another rendition of it, this time with a smaller FOV and focusing in bringing out the hydrogen clouds (the pink spots) and the dust clouds (the brown filaments) close to the nucleus, which is not so common to see.

In the end I enjoyed it so much that took a crop and also publish as a separated image.

I hope you enjoy.

Tout d'abord, bonne année 2023 à tous 😁 ! On commence enfin l'année avec cette première publication qui aura su se faire attendre (traitement galère entre airglow, brume, nuages et givre ).

.

✨ La pluie d’étoiles filantes des “Géminides” est la plus prolifique de l’année avec environ 150 météores/heure lors de son pic d’activité ! Le problème, c’est que ce pic arrive au milieu du mois de Décembre et la météo est souvent mauvaise à cette période. Cet hiver ne fait pas exception. On compte les nuits dégagées de ces 2 derniers mois sur les doigts d'une main 😪. C'est très frustrant de faire de l'Astro en France et encore plus dans ch'Nord ️.

Nella costellazione del Cefeo si trova l'ammasso aperto IC1396 circondato da una nebulosa ad emissione che fa parte di un'ampio sistema di nubi molecolari HII. Spicca la nebulosa oscura vdB 142 chiamata Proboscide d'elefante.

Ho combinato riprese effettuate con filtri differenti e ho provato a fonderle insieme, ho trovato il risultato gradevole e le informazioni maggiormente complete rispetto alle sigole riprese. Esposizioni da 10 minuti per ciascun filtro, 114 con il filtro broadband SV260, 61 con il dualband Antlia ALP-T 5 nm (Ha e O3) e 16 con il L-Synergy Optolong dualband 7nm (S2 e O3).

Per catturare le stelle è stata aggiunta circa un’ora di integrazione in pose da 60 secondi con filtro broadband SV260.

Il tutto è stato ripreso con un telescopio Newton 150/600 dotato di correttore Tecnosky 0.95x, camera Tecnosky Vision 571C e montatura EQ6-R Pro, elaborazione in PixInsight.

In the constellation Cepheus lies the open cluster IC1396, surrounded by an emission nebula that is part of a large system of HII molecular clouds. The dark nebula vdB 142, known as the Elephant's Trunk, stands out.

I combined images taken with different filters and tried merging them. I found the result pleasing and the information more complete than the individual images. 10-minute exposures were taken for each filter: 114 with the broadband SV260 filter, 61 with the dualband Antlia ALP-T 5nm (Ha and O3), and 16 with the dualband L-Synergy Optolong 7nm (S2 and O3).

To capture the stars, about an hour of integration was added in 60-second exposures with the broadband SV260 filter.

The whole thing was captured with a 150/600 Newtonian telescope equipped with a Tecnosky 0.95x corrector, a Tecnosky Vision 571C camera and an EQ6-R Pro mount, processed in PixInsight.

🌀 M81 & M82 // Galaxies de Bode et du Cigare

.

✅ Tout premier test du télescope avec la caméra refroidie et les premiers résultats sont encourageants ! C’est d’ailleurs également ma toute première mosaïque du ciel profond (2 tuiles). Malgré un échantillonnage juste, le niveau de détail atteint est tout de même assez bluffant. J’ai pu profiter de la qualité du ciel nocturne de notre spot favori avec @otsugaphoto pour essayer d’avoir rapidement du signal. Néanmoins le faible temps de pose induit encore beaucoup de bruit et je ne peux pas tirer les détails au maximum comme j'aimerai. Il y a par exemple les IFN qui apparaissent au traitement si je tire fort sur les curseurs mais je préfère ne pas détériorer la qualité de l'image.

.

🌌 M81 est une galaxie spirale-barrée située qui fut découverte par Johann Elert Bode en 1774. La répartition de la masse de la galaxie n’est pas homogène en raison de l’effet de marée dû à la proximité (~ 150 000 AL) d’une autre galaxie moins massive.

.

M82, la galaxie du Cigare, est une galaxie irrégulière située dans la constellation de la Grande Ourse. Avec M81, ces deux galaxies forment avec d’autres un groupe de galaxies proche du nôtre. M82 représente le prototype d’une galaxie irrégulière. Son noyau, qui semble avoir énormément souffert d’un rapprochement avec M81 il y a quelques centaines de millions d’années, se trouve dans une phase de violente activité stellaire et présente de remarquables raies sombres. Il s’agit d’une galaxie à sursaut de formation d’étoiles. De grandes quantités de matières sont éjectées à environ 1 000 km/s de la galaxie. On suppose que ces éjections sont dues à l’explosion de supernovas.

.

This is a bit of an odd ball as it does not follow anthing like I have done before. I found this Dark looking structure on Stellarium but it was not named so could not select it by writing the name. I was able to use the cool feature in Nina Select it in Stellarium and it brings it into Nina as a target. The star is HIP 54413 at least I knew that part from Stellarium This is two nights worth of shots and about 6 goes at trying to edit this which is so different to how I have done all the others.

I think this is pushing the limits of the ED 80 with all this very light dusty part of the sky. The mount performed flawlessly so really happy with the two upgrades.

Premier post de cette nouvelle année. J'en profite pour vous souhaiter une excellente santé, du bonheur dans vos vies mais aussi une montagne de merveilleux clichés !

.

Quoi de mieux qu'une photo de ma Champagne natale pour commencer 2022 🍇 ?! Voici une image que j'avais teaser il y'a plusieurs mois déjà, elle a été prise au printemps dernier au moulin de Verzenay. Ayant assez peu l'occasion de faire de l'Astro dans la Marne, je voulais marquer le coup en essayant de réaliser mon premier "deepscape", un astro-paysage au téléobjectif en ayant au moins une nébuleuse du ciel profond.

.

La fin du printemps était une période idéale pour réaliser un deepscape ici. La Voie Lactée se lève très horizontalement et la région du Cygne se trouve à l'Est juste au dessus du coteau ou se trouve le moulin, parfait pour une prise de vue en contre-plongée. C'est aussi le moment de la floraison des vignes, les feuilles sont d'un vert pétant et on devine timidement les premiers raisins.

.

Au 135mm, je n'avais pas l'ensemble du paysage ou alors pas assez de ciel. J'ai alors réalisé un panorama de 4 photos verticales. Quatre pour le sol sans suivi et quatre pour le ciel avec suivi. Pour contrer la pollution lumineuse de Reims qui se trouve 20km dans mon dos, j'ai utilisé le filtre Nisi Natural Night. Vous pouvez distinguer facilement la nébuleuse de l'Amérique du Nord à gauche et la nébuleuse du papillon (Sadr) à droite. Ce sont des cibles assez facile avec un APN défiltré car très lumineuses.

IC2177 is a region of nebulosity that spans about 240 light-years along the border between the constellations Monoceros and Canis Major, at a distance of about 3,800 light-years from Earth.

This is not the first time I have shot at the same targets with both the color and mono cameras, but it is the first time I have used both data sets for a single image. The color camera data was used as the Luminance channel, along with the Halpha data, and for the final result I used an LRGB approach.

If you've seen my feed, you know I've been working on deepspace landscapes like this basically all winter. This is my most recent effort. The foreground is an old fire tower and observation deck. In the sky, from left to right, is the M38 star cluster, the tad pole nebula (the blueish object), and then the flame nebula just above. I thought the idea of the flame nebula and a fire tower was poetic in a way.

My goal with this series has been to illustrate just how big these objects in the night sky are, by showing them near terrestrial objects. Ah if only our eyes could see this!

The Rosette nebula is one of my favorite targets. The shape and detail make it one of the most interesting deep sky objects in the northern hemisphere. Located in the constellation Monoceros, it also contain the open cluster NGC 2244. This cluster provides the solar radiation that is exciting the surrounding gas and causing the striking glow.

Second and last attempt in 2021 to shoot the M42 nebula, in this time with the same unmodified Sony A7M3 camera and Sony FE 100-400 GM lens, but I use the tracker Skytwatcher AZ-GTI in EQ Mode and QHY guided camera with 60mm tube to increase exposure times.

The location and the weather conditions were ideal, but everything began to go wrong when I did not carry the AC50s Powerbank with me to power the laptop, badly enough that I always carry another portable Powerbank for the tracker, this except the day. During the session, the Sony A7M3 did not admit to connecting any of the 2 Mini-USB cables that it carried for the remote shutter camera control, so I finally decided to launch the shots with the wireless remote control and keeping track of the exposure time.

Despite all this, for a 54 min. total exposure time, quite a few details of this magnificent nebula have been captured with this equipment. It is definitely worth the effort to use guided mount and tracking, there is a brutal difference in the results obtained compared to using only a tripod and low exposure times.

I will continue in future sessions trying to capture more light by increasing the number of shots and exposure.

Segundo y último intento en 2021 de captar a M42, en esta ocasión con la misma cámara no modificada Sony A7M3 y el objetivo Sony FE 100-400 GM, pero utilizo la montura guiada Skytwatcher AZ-GTI EQ Mode y una cámara de seguimiento QHY con tubo de 60mm para aumentar los tiempos de exposición.

La nueva ubicación y las condiciones meteorológicas fueron las idóneas, pero todo se empezó a torcer cuando no lleve conmigo el Powerbank AC50s para alimentar el portátil, manos mal que siempre llevo para la montura otro Powerbank portable, esto salvo el día. Durante la sesión, la Sony A7M3 no admitió conectar ninguno de los 2 cables Mini-USB que llevaba para el auto disparador, por lo que finalmente decidí lanzar las tomas con el mando a distancia y llevando la cuenta del tiempo de exposición.

A pesar de todo ello, para ser una toma de 54 min. de tiempo total de exposición, se han captado bastantes detalles de esta magnífica nebulosa con este equipo.

Definitivamente merece el esfuerzo utilizar montura guiada y seguimiento, hay una diferencia brutal en los resultados obtenidos con respecto a utilizar trípode fijo y bajos tiempos de exposición.

Seguiré en futuras sesiones intentando captar más luz aumentando el número de tomas y exposición.

The Spaghetti Nebula is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. The nebulous area has an almost spherical shell and a filamentary structure. It is believed that the stellar explosion left behind a rapidly spinning neutron star known as a pulsar in the nebula core, emitting a strong radio signal. Sh2-240 is approximately 3,000 light-years from earth.

The Whirlpool Galaxy is one of the most spectacular sights when observing the night sky. Located at about 31 million years from us, it is a grand design spiral galaxy interacting with another one, in a slow dance by which both will merge within several million years. As a result of this, tidal streams of stars are swirling around, here seen as the faint light patch around. The Whirlpool Galaxy has lots of star formation areas - the bluish areas reveal the presence of young and hot stars.

We haven't had a lot of clear skies during the "COVID days", however when we have had some I've tried to take advantage of it. In the mean time though, I've been working on some older images like this one. I captured the pictures that make up this image last year in Arizona, and then recently re-processed them and am SUPER happy with the result. The night sky is just so intriguing!

This deep-space image showcases two stunning nebulae in the constellation Auriga: the Tadpoles Nebula (IC 410) at the top center, and the Flaming Star Nebula (IC 405) toward the lower left.

IC 410, the Tadpoles Nebula, is an emission nebula located about 12,000 light-years from Earth. It surrounds the young star cluster NGC 1893, whose massive, energetic stars light up and shape the surrounding gas. The 'tadpoles' that give the nebula its nickname are dense streams of dust and gas about 10 lightyears long. They are assumed to be sites of star formation.

IC 405, the Flaming Star Nebula, lies in the lower left portion of the image. This beautiful mix of emission and reflection nebula is about 1,500 light-years away and is illuminated by the hot, massive star AE Aurigae. Its flowing, flame-like filaments of gas and dust give the nebula its name and striking appearance.

Set against a dense star field, this image uses narrowband imaging techniques to highlight different elements: hydrogen, oxygen, and sulfur. The result reveals both the structure and composition of these rich star-forming regions.

This image is a HSO combination to simulate a view similar to the color balance of the human vision.

Sembrerà incredibile!!! Eppure ho "inseguito" questa nebulosa, nota come Nebulosa Testa di Pesce

e catalogata con le sigle NGC896 o IC 1795, dal 9 dicembre 2025 fino al 14 gennaio di quest'anno per ben 5 notti. Raramente il meteo nella mia zona è stato così avverso: spesso nuvoloso o coperto, pioggia e persino il ciclone Harry, che ha recato molti danni soprattutto nelle coste orientali della Sicilia , Calabria e Sardegna.

Ho racimolato comunque più di 23 ore di integrazione anche se durante le prime 3 sessioni la qualità del cielo era mediocre e con la luna il 09/12 al 76%, il 10/12 al 66% e il 28/12 al 58%. E per questo motivo volevo integrare ulteriormente ma ormai la costellazione di Cassiopea è troppo bassa.

Ad ogni modo in questa occasione ho potuto utilizzare 3 filtri multi banda stretta (oltre all'Optolong L-eNhance anche l'SVBony SV220 Ha+OIII e l'SV220 SII+OIII, avuti in prestito dal mio amico Vincenzo Randazzo che ringrazio). Ho potuto fare così un test di comparazione:

-L-eNhance e SV220 Ha+O3 sono abbastanza simili anche se l'SVBony sembra avere una risposta migliore per l'Ha;

- SV220 SII+OIII invece mi ha sorpreso per la sua buona risposta sull'OIII.

E così ho combinato 279 frames ed elaborato il Masterlight con l'intento di estrapolare non solo più dettagli possibile ma anche di equilibrarla cromaticamente. Forse si potrebbe fare di meglio ma speriamo in una prossima volta.

It may seem incredible!!! Yet I "chased" this nebula, known as Fish Head Nebula and cataloged with the acronyms NGC896 or IC 1795, from December 9, 2025, until January 14 of this year for a full 5 nights. Rarely has the weather in my area been so adverse: often cloudy or overcast, rain, and even Cyclone Harry, which caused a lot of damage, especially on the eastern coasts of Sicily, Calabria, and Sardinia.

I still managed to collect more than 23 hours of integration, even though during the first three sessions the sky quality was mediocre, with the moon at 76% on December 9th, 66% on December 10th, and 58% on December 28th. For this reason, I wanted to integrate further, but the Cassiopeia constellation is now too low.

In any case, on this occasion I was able to use three narrowband filters (in addition to the Optolong L-eNhance, also the SVBony SV220 Ha+OIII and the SV220 SII+OIII, borrowed from my friend Vincenzo Randazzo, whom I thank). I was thus able to perform a comparison test:

- L-eNhance and the SV220 Ha+O3 are quite similar, although the SVBony seems to have a better response for Ha;

- The SV220 SII+OIII surprised me with its good response for OIII.

So I combined 279 frames and processed the Masterlight with the aim of not only extracting as much detail as possible but also balancing it chromatically. Perhaps it could be done better, but let's hope for another time.

✌️ "V" zodiacal et arche hivernale ✨.

Au-revoir à Orion et son ciel d'hiver qui nous quittent en ce mois d'Avril. On se retrouve en Octobre pour de nouvelles astrophotos . Je n'ai malheureusement pas pu trop en profiter d'une part à cause de la météo et d'autre part à cause d'un autre projet photo qui me prend beaucoup de temps 👀.

.

🆑 Ici, c'est un peu mon Chili à moi 😂. Probablement un des meilleurs ciels de notre région (disons plutôt le moins pire). Il me faut environ 1h15 de route de la maison pour profiter de ce ciel assez correct. Situé au fin fond du Pas-de-Calais, cet endroit est classé dans une zone Bortle 4 (proche Bortle 3). La meilleure valeur de la qualité de ciel que j'ai pu mesurer ici au SQM (Sky Quality Meter) est de 21.47. Le maximum étant 22.00, il correspond aux endroits sur Terre où le ciel est le plus pur, sans aucune pollution lumineuse. Cette différence entre les 2 valeurs paraît minime mais elle est en fait énorme et la différence sur la pureté du ciel l'est tout autant.

.

🔭 Alors certes je n'ai pas la puissance des télescopes du désert chilien mais j'essaye de me débrouiller avec mon Newton 250/1000 . C'est un petit parallèle avec les moyens du bord comparé aux énormes observatoires qui sont là-bas. On voit beaucoup d'arches galactiques au-dessus des immenses coupoles, je voulais mettre à mon tour en valeur la bête . J'avais cette compo en tête du backstage : un "V" formé sous l'arche de la Voie Lactée. La cible ce soir-là était la galaxie M51, le post arrive bientôt. On peut observer de gauche à droite : le complexe d'Orion, la Voie Lactée, la lumière zodiacale, la galaxie d'Andromède et bien d'autres nébuleuses en H-alpha.

La Nebulosa Grotta (Sh2-155 o C9) è una splendida nebulosa a emissione situata nella costellazione di Cefeo, a circa 2400 anni luce di distanza dalla Terra.

Per questa immagine ho utilizzato filtri interferenziali dualband, che mi hanno permesso di realizzare una composizione in Hubble Palette: il rosso è assegnato allo zolfo ionizzato (S II), il verde all’idrogeno alfa (H α) e il blu all’ossigeno doppiamente ionizzato (O III).

Le pose guidate da 600 secondi sono state:

67 scatti con filtro Antlia ALP-T 5 nm, per H α e O III;

87 scatti con filtro Optolong L-Synergy 7nm, per S II e O III.

Per le stelle, 1 ora di integrazione in pose da 60 secondi con filtro broadband SV260.

The Cave Nebula (Sh2-155 or C9) is a splendid emission nebula located in the constellation Cepheus, about 2,400 light-years away from Earth.

For this image, I used dual-band interference filters, which allowed me to create a composition in the Hubble Palette: red is assigned to ionized sulfur (S II), green to alpha hydrogen (H α), and blue to doubly ionized oxygen (O III).

The 600-second guided exposures were:

67 shots with the Antlia ALP-T 5 nm filter, for H α and O III;

87 shots with the Optolong L-Synergy 7 nm filter, for S II and O III.

For the stars, 1 hour of integration in 60-second exposures with the SV260 broadband filter.

Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes stand out in this colorful skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and red,blue and green filters. The atomic emission is powered by energetic radiation from the central hot stars. Their powerful winds and radiation sculpt and erode the denser pillar shapes and clear out a characteristic cavity light-years across the center of the natal cloud. Stars could still be forming inside the pillars by gravitational collapse but as the pillars are eroded away, any forming stars will ultimately be cutoff from their reservoir of star stuff. This field of view spans over 40 light-years at the estimated distance of NGC 7822 [Text adapted from APOD]
