Recently fledged blue tit [Cyanistes caeruleus]
This little guy was calling out to his mother to feed him. Here, the mother bird is passing just over his head to feed one of his siblings. He is very excited and begins to vibrate his wings...apparently, a visual stimulus to the parent, but one of the cutest, most adorable things I have ever seen.

A feeling for composition is a great asset. I think it is very much a matter of instinct. It can perhaps be developed, but I doubt if it can be learned. To achieve his best work, the young photographer must discover what really excites him visually. He must discover his own world :-)

Hey ! Ca faisait un moment que je n'avais pas posté un peu d'astro. Mais c'est normal, cet été j'ai accumulé pas mal de données que je commence à peine à traiter. Là, c'est un projet de taille moyenne : près de 13h sur la même cible avec des poses "longues" de 6 minutes. Cette cible, je l'ai choisie parce qu'elle est chouette et aussi parce que j'avais besoin de tester des choses (matériel, poses longues, nouveau process de traitement) sur une cible plutôt lumineuse avant de faire de même sur un projet beaucoup plus gros que je dois encore traiter (chhhht ! surprise !).
Bref, là, c'est la région du cygne comprise entre Sadr et Eta cygni (qui n'apparait pas sur la photo car j'ai fait une petite erreur et j'ai dû éliminer de petites régions de la photo).
De façon générale, les couleurs proviennent des gaz interstellaires éclairés (reflexion) ou excités (emission) par les étoiles environnantes. Les gaz environnants, rouges, sont ceux de l'immense nébuleuse d'hydrogène (raie de l'Hydrogène alpha) de la région du cygne. Les couleurs bleues proviennent des raies de l'Oxygène III et de l'Hydrogène beta.
Au milieu, on distingue sans peine la nébuleuse du croissant (NGC 6888 / Caldwell 27). Distante de 5000 années lumières environ, elle est produite par une étoile dite de Wolf-Rayet. Cette étoile emet des vents solaires rapides qui exercent une pression radiative sur la matière éjectée par cette même étoile et produite il y a longtemps lorsqu'elle était plus jeune de quelques centaines de milliers d'années. Elle forme une sorte de bulle dite "bulle de Wolf-Rayet". La lumière de la bulle de matière est due à son ionisation par la lumière intense de son étoile centrale. Sa couleur rouge provient de l'hydrogène (bande alpha) tandis que sa couleur bleue vient de sa richesse en azote et carbone.
A droite, on voit une sorte de chapeau rouge avec un peu de bleu dedans : la nébuleuse de la tulipe (SH2-101), une nébuleuse en émission distante de 8777 AL.
La tâche rouge presque ronde bien marquée en haut de l'image, à côté de l'étoile brillante 36 cygni, c'est Sharpless 104 (SH2-104), une nébuleuse distante d'environ 13000 AL.
Entre SH2-1010 à droite et SH2-104 à en haut à gauche, on a au premier tiers depuis la tulipe un amas ouvert, NGC 6871, et au 2nd tiers depuis la tulipe (1er tiers depuis SH2-104), un arc bleu bien net vraisemblablement d'Oxygène III. Là, j'ai du chercher pour avoir des infos, en particulier sur ResearchGate (je suis chercheur après tout ;). Cet arc, c'est la coquille de WR 134 / WR 135. Elle est associée aux étoiles Wolf-Rayet WR 134 et WR 135. Elle est le plus souvent appelée simplement « WR 134 shell » ou « WR 134 nebula » dans le milieu amateur. Ce qui est remarquable est que ce n’est pratiquement pas une nébuleuse H-alpha classique. Le croissant est très fortement dominé par l'OIII, ce qui explique exactement son aspect turquoise sur le traitement. Les observations montrent des filaments OIII situés surtout d’un côté de WR 134, légèrement en avant des filaments H-alpha : c’est typique d’un front de choc produit lorsque le vent extrêmement rapide d’une Wolf-Rayet rencontre le milieu interstellaire. Les observations en bande étroite donnent une taille du croissant brillant d’environ 15′ (la moitié de la pleine lune), avec une structure beaucoup plus étendue et beaucoup plus faible autour. Et il y a une subtilité assez intéressante : l’attribution à WR 134 n’est pas complètement tranchée. WR 135 se trouve seulement à une quinzaine de minutes d’arc de WR 134. Une étude cinématique en H-alpha, HI 21 cm et CO publiée par Sitnik & Lozinskaya en 2009 conclut que la grande bulle HI de la région est probablement liée à WR 135 plutôt qu’à WR 134, tandis que des mouvements d’expansion du gaz ionisé, jusqu’à environ 50–80 km/s, sont observés autour des deux étoiles. D'après les auteurs, il est donc plus rigoureux d’étiqueter cette région « WR 134/135 shell – OIII», même si « WR 134 shell » reste l’usage courant.
Il y a beaucoup d'autres structures, notamment les nébuleuses brillantes (qui sont plus ou moins toutes liées), les LBN (Lynds Bright Nebulae), et les nébuleuses sombres, les LDN (Lynds Dark Nebulae).
Immédiatement à droite à la pointe de la tulipe se trouve le microquasar Cyg X-1. La zone environnante possède un véritable front de choc H-alpha / OIII avec une vitesse de choc d'au moins ~100 km/s.
L'étoile 34 Cygni, surnommée par Christiaan Huygens le revenant de Swan, a été pensée pendant longtemps comme une nova à cause d'éruptions régulières. Cependant, cette étoile distante de 5300 AL est vraisemblablement plutôt une variable bleue lumineuse (LBV). Ce sont des étoiles rares qui ne se forment que dans des régions d'intense formation d'étoiles.
Concernant le setup, j'ai utilisé un Canon 6D défiltré partiellement par IR-Photomax, une petite lunette de chez SvBony, la SV555, un astrographe APO 54/243 de 5 lentilles en 3 groupes, un filtre SVBony SV220 (dual band : OIII + H-Alpha à 7nm), un système autofocus Zwo EAF. Le tout était monté sur monture Skywatcher AZ-EQ5 et autoguidé par une lunette Kepler 50/162 + camera Zwo Asi 120 mm + Zwo AsiAir Mini.
J'ai fait 142 poses de 6 min, n'en conservant que 128, soit 12h48 de cumul sur 3 nuits du 27 au 30/07/26. A cela s'ajoutent 30 flats par session (90 flats), 30 darks de 6 min par session (90 darks), 35 offsets.
Le traitement a été fait sous Siril 1.4 + les scripts Veralux, Cosmic Clarity, SyQon Prism Mini + Gimp.

Hey! It had been a while since I last posted some astro stuff. But that’s normal: this summer I accumulated quite a lot of data that I’m only just starting to process. This one is a medium-sized project: nearly 13 hours on the same target, with “long” 6-minute exposures. I chose this target because it’s cool, and also because I needed to test a few things (equipment, long exposures, new processing workflow) on a fairly bright target before doing the same on a much bigger project that I still have to process (shhh! surprise!).
Anyway, this is the region of Cygnus between Sadr and Eta Cygni (which does not appear in the photo because I made a small mistake and had to crop out small regions of the image).
In general, the colors come from interstellar gases illuminated (reflection) or excited (emission) by the surrounding stars. The surrounding red gases are those of the immense hydrogen nebula (Hydrogen-alpha line) in the Cygnus region. The blue colors come from the Oxygen III and Hydrogen-beta lines.
In the middle, the Crescent Nebula (NGC 6888 / Caldwell 27) is easy to make out. Located about 5,000 light-years away, it is produced by a so-called Wolf-Rayet star. This star emits fast stellar winds that exert radiation pressure on material ejected by the same star and produced long ago, when it was a few hundred thousand years younger. It forms a kind of bubble known as a “Wolf-Rayet bubble.” The light from the bubble of matter is due to its ionization by the intense light of its central star. Its red color comes from hydrogen (alpha band), while its blue color comes from its richness in nitrogen and carbon.
On the right, you can see a sort of red hat with a little blue inside it: the Tulip Nebula (SH2-101), an emission nebula located 8,777 light-years away.
The well-defined, almost round red patch at the top of the image, next to the bright star 36 Cygni, is Sharpless 104 (SH2-104), a nebula located about 13,000 light-years away.
Between SH2-1010 on the right and SH2-104 at the upper left, one third of the way from the Tulip is an open cluster, NGC 6871, and two thirds of the way from the Tulip (one third of the way from SH2-104), there is a very distinct blue arc, most likely Oxygen III. I had to do some searching to find information about this, particularly on ResearchGate (I am a researcher, after all ;). This arc is the shell of WR 134 / WR 135. It is associated with the Wolf-Rayet stars WR 134 and WR 135. It is most often simply called the “WR 134 shell” or “WR 134 nebula” in the amateur astronomy community. What is remarkable is that it is hardly a classic H-alpha nebula at all. The crescent is very strongly dominated by OIII, which explains exactly its turquoise appearance in the processing. Observations show OIII filaments located mainly on one side of WR 134, slightly ahead of the H-alpha filaments: this is typical of a shock front produced when the extremely fast wind of a Wolf-Rayet star encounters the interstellar medium. Narrowband observations give the bright crescent a size of about 15′ (half the full Moon), with a much more extended and much fainter structure around it. And there is a rather interesting subtlety: the attribution to WR 134 is not completely settled. WR 135 lies only about fifteen arcminutes from WR 134. A kinematic study in H-alpha, HI 21 cm and CO published by Sitnik & Lozinskaya in 2009 concludes that the large HI bubble in the region is probably associated with WR 135 rather than WR 134, while expansion motions of the ionized gas, reaching about 50–80 km/s, are observed around both stars. According to the authors, it is therefore more accurate to label this region “WR 134/135 shell – OIII,” even though “WR 134 shell” remains the commonly used name.
There are many other structures, particularly the bright nebulae (which are more or less all related), the LBNs (Lynds Bright Nebulae), and the dark nebulae, the LDNs (Lynds Dark Nebulae).
Immediately to the right of the tip of the Tulip lies the microquasar Cyg X-1. The surrounding region has a genuine H-alpha / OIII shock front with a shock velocity of at least ~100 km/s.
The star 34 Cygni, nicknamed the “Revenant of the Swan” by Christiaan Huygens, was long thought to be a nova because of its regular eruptions. However, this star, located 5,300 light-years away, is more likely a luminous blue variable (LBV). These are rare stars that form only in regions of intense star formation.
As for the setup, I used a Canon 6D partially modified by IR-Photomax, a small refractor from SvBony, the SV555, a 54/243 five-element APO astrograph with 5 lenses in 3 groups, an SVBony SV220 filter (dual band: OIII + H-Alpha at 7 nm), and a ZWO EAF autofocus system. Everything was mounted on a Skywatcher AZ-EQ5 mount and autoguided using a Kepler 50/162 guidescope + ZWO ASI 120 mm camera + ZWO ASIAir Mini.
I took 142 6-minute exposures, keeping only 128 of them, for a total integration time of 12h48 over 3 nights from 27 to 30/07/26. In addition to this, I took 30 flats per session (90 flats), 30 6-minute darks per session (90 darks), and 35 bias frames.
Processing was done with Siril 1.4 + the Veralux, Cosmic Clarity, SyQon Prism Mini scripts + GIMP.

One Rail Australia locos GWB102/ALF18 with Adelaide to Darwin 6AD1 intermodal service in tow, drop down through the curves on the other side of Wirrappa on Saturday 12 March 2022.
Taken four minutes after the previous upload of this train, I was able to drop the ISO from 4000 to 1600. Composition was a battle - do I include the whole curve to the left or make the glint off the locos the centerpiece?

An LED exciter-lamp retrofit and power supply I made for my Kalart-Victor 70- and 75-series projectors. I fabricated a holder/heat sink to mount a high-intensity LED onto and mounted the assembly onto to a plastic disc. I then mounted the assembly into a sound drum unit from a parts projector, using the drum's end cap to hold it in place through holes drilled in the disc for the purpose, to avoid modifying the drum.
The power supply was made from a power supply module, case, and other parts purchased through electronics parts suppliers. I modified the case, installed the parts, and wired everything up.
Those vintage Kalart-Victors are solid, quiet-running machines, their major weakness being a lot of 60-Hertz (or 50Hz for export models) hum in the sound. Unlike other projector makes using DC-powered lamps, the exciter lamps in these machines were AC-powered; thick filaments in the lamps, intended to minimize hum, did not completely squelch the noise. I originally envisioned replacing the original lamp with some kind of internal retrofit, untill I had an LED light-bulb moment. With this gadget, I just remove the old-school exciter lamp and slip this retrofit into place and kiss the exciter lamp hum goodbye.

This is yet another image from telescope live. Although the total exposure time was a little over 45 minutes, the fact that Orion is so bright meant that the snr was still quite high. I’ve been iterating through versions of this image to figure out the best method of HDRing the core, and I feel like I’ve been settling on a pretty solid method using MMT. The detail in the core that I managed to pull out is really interesting to look at, so I highly recommend looking at the full PNG or the cropped views down below.
Few astronomical sights excite the imagination like the nearby stellar nursery known as the Orion Nebula. The Nebula’s glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud. Many of the filamentary structures visible in the featured image are actually shock waves – fronts where fast moving material encounters slow moving gas. The Orion Nebula spans about 40 light years and is located about 1500 light years away in the same spiral arm of our Galaxy as the Sun. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion. The featured image, taken last month, shows a two-hour exposure of the nebula in three colors. The whole Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years.
