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.

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.

Orion is setting earlier every day now. Time to post another image of my favorite winter constellation, before the "Orion Season" draws to an end.
I captured this 'deep' exposure in early January, when it was still possible see Orion rising.
The night before, I was partially fogged out and even though it cleared again later in the night, I missed the rise if Orion.
I therefore decided to hike to a slightly higher spot the next night and face the cold one more time. Shortly after sunset, the fog started to form again, but thanks to my higher vantage point, the fog top stayed some 200m below my position, enabling my to successfully capture my planned composition.
The low fog not only added a special mood to the foreground, it also blocked a good part of the light pollution and thus enabled me to capture one of my most detailed Orion widefields to date, with a popping Barnard's Loop and an almost 3 dimensional Witchhead Nebula.
Sometimes, landscape astrophotograohers are walking a thin line. A few meters of hight difference or a slight difference in temperature or air pressure can be all that separates a successful shooting from a total failure.

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.

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.

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 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.

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.

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.
English below
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.
☄️ 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..

First of all, Merry Christmas to all astro folks and friends out there.
This post is about my maiden voyage with the AG14 astrograph (Recently acquired Orion Optics large Newt)
After quite some time spent on a learning to colimate the the beast using the Catseye system and other miscellaneous odds and ends required for basic setup, such as, the need for an additional counterweight. The clouds finally cleared last night and I was able to run some test shots with the new Astrograph. This image is made of a stack 30 un-calibrated 1800 sec bin x 2 subs.

This was a trial with the MeLE Nuc to see if things where right I had three nights to "play" with the whole set up. The Nuc sits under the Skywatcker ED80 so 5 long 3 m cables gone going to the laptop they all stay up on the top of the scope.
Night one did not work out at all could not get plate solve to work properly could hardly see the stars. After some two hours I gave up went to bed.
Night two I bumped plate solve exposure by more than double the time finally plate solve worked. So I thought I would try some thing to check if the system worked. On taking the very first photo it would not down load and I lost the camera. The usb cable that was supplied with the camera died. My only option was to bundle up my normal 3m cable and connect up to the camera and the Nuc and try a fix the whole lot to the scope. The whole thing looked like it was normally what I was use to seeing.
Night three I had to remove the dead cable and wrap the 3m one around the guide scope. I decided to do a real test set up the system to start on it own 6:45Pm. I sat in side the computer room and watched the sequence start flawless totally on its own. This is the result of those two nights some more 1m cables on there way to lessen the weight of cables. Plate solve has gone back to its normal 10 sec exposure time.

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 ️.

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.

🌀 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.

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.

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.

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.

Orion Nebula / Nebulosa de Orión (M42, Messier 42, NGC 1976)
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.

Volcanic turmoil, radiating out from the propeller nebular . DWB-111 Propeller Nebula is an emission nebula in the constellation Cygnus
This is the next installment of my 2016 Cygnus exploration. This image is made up of two panels and has an integration of approximately 50 hours of photography.
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!
Explanation: Interstellar dust clouds and bright nebulae abound in the fertile constellation of Orion. One of the brightest, M78, on center in this colorful telescopic view, covering an area north of Orion's belt. At a distance of about 1,500 light-years, the bluish nebula itself is about 5 light-years across. Its blue tint is due to dust preferentially reflecting the blue light of hot, young stars in the region. Dark dust lanes and other nebulae can easily be traced through this gorgeous skyscape. The scene also includes the remarkable McNeil's Nebula -- a newly recognized nebula associated with the formation of a sun-like star, and the telltale reddish glow of many Herbig- Haro objects, energetic jets from stars in the process of formation.

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.

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.

M 3 is found in the constellation Canes Venatici and is one of the three brightest globular clusters in the northern sky.
Discovered by Charles Messier in 1764 and later by William Herschel in 1784.
I chose this cluster because when the moon is bright (99%), you need a bright image to be able see through the Moon glow in the sky. We have been having really poor weather in southern Spain and this was a small opportunity to take an image in between the clouds. Unfortunately the humidity was at 100% for the entire session making for slightly blurred stars, but I though it would be a challenge to see what I could make of just 2.5 hours of data under extreme conditions.
A single night of imaging in June 2023 from my home in Gérgal, Spain.
