The Witch Head Nebula in Orion
You may remember I shared a picture of this beautiful area of the night sky a year ago. I recently tripled the time I spent collecting information from this little patch of dark sky before it dipped below the horizon. The witch lies in the lower right (northern hemisphere) of the constellation Orion, next to a super massive bright blue star called Rigel. The nebula glows faintly from the blue light from this star, hence it is known as a reflection nebula. It is so faint that your eyes will barely see it, even through a good telescope (maybe on a very good telescope!). These objects in the night sky are so faint, that the more images taken, the more and more it shows up in the final photograph. Rigel is 870 light years from earth, and is calculated to be anywhere from 61,500 to 363,000 times brighter than our own star!
A definite improvement on my last years 20 minute effort, this is approximately 1 hour 10 mins on this target. Still no where near enough. What frustrates me about this is I know I can do even better than this; but the target was really low on the horizon and I was contending with a moon and the image got a mild ring in if from the light of the 40% moon which I had to painstakingly remove in photoshop. I had to kill some of the background signal in order to make this work. Still, progress is progress and I'll take it.
Next year I will be back with an even deeper version of this truly fascinating area of the night sky, so stay tuned!

Aurora in the Neighbourhood
So as with every time aurora comes around, we get a lot of posting and rumbling on social media about how fake the resulting photographs are and how over edited they seem. Of course...you will find plenty of oversaturated images just like you will find with any genre of photography and part of that comes down to personal taste.
However.
If you are not seeing the colours with the storms we have had recently in Scotland (ps you need to be out when it is most active - activity constantly wanes and rises)...you either have really poor eyesight (admittedly, an uncontrollable factor in the aurora seeing equation)....and probably (the larger part of the equation), poorly night adapted eyes. Or perhaps one or the other. It takes the average 'set' forty five minutes in darkness with no lights other than starlight hitting the back of our retinas before the cells that interpret colour become most active. You might have heard about these photoreceptors in our retinas; known as rods and cones. In low light, it is the rod cells that generally give us the bulk of our vision, they immediately work hardest to let us see in the dark - but they are very poor at detecting and relaying colour information to the brain. Ever noticed how when you awake from sleep at night, that you basically see in black and white (and also a very noisy image)? This is why. Give it time, the cones become active but they are slow to awaken as they work more in higher light levels. Again, the rough time for the average eye balls is around forty five minutes in darkness. Their sensitivity goes instantly when light from artificial sources enters the eye again - for example, phones, torches, streetlights, etc.
If you have dark adapted eyes, you will see colour even with more gentle aurora activity...I promise you. I dislike posts such as I have seen the last few days for a few reasons because it implies the camera lies and our eyes are the only real test. It also implies that I am some how trying to decieve the viewership here; which of course is never my intention. Can these people posting this now see gamma rays too? Because if you take your eyes as the ultimate test they detect less than 0.05% of the electromagnetic spectrum. The camera is, instantly a great deal better at seeing than your eyes - but please give your eyes a fighting chance and don't dismiss our ability to see such things. If you understand this; you won't be disappointed at all. Let's not waste time discussing over edited pictures. We know that exists and always will, but let us not decry that you will be disappointed when aurora hunting because you saw someone post some over edited pictures.
This image, taken in the local neighbourhood shows the very 'visible to eye' Aurora on Sunday night in Scotland which was incredible. So strange to see the mystical Northern Lights over the local neighbour hood like I reside in a much more northernly latitude than I do. The previously shared picture is a better location of course, but this is stronger green colour, without the red pillars above it, previously shown. As you can see I continued to shoot some deep sky images (more coming soon if it all works out) whilst using another camera to capture the lights before leaving for the night.
I hope this has been informative! Lastly, since the moon is becoming ever larger, the chances drop of seeing or making a good picture. Though, cloud always has the final say in what we can see.
Thanks for reading,
Steve
Nel cuore della costellazione del Cigno, a circa 2.590 anni luce dalla Terra, si erge la Cygnus Wall: un’imponente scogliera di gas e polveri, lunga quasi 20 anni luce, che brilla di un rosso ardente sotto la luce delle giovani stelle calde vicine. È la parte più luminosa della Nebulosa Nord America (NGC 7000), che nella nostra prospettiva ricorda il “Golfo del Messico”.
Dalla città, con il mio SkyWatcher 200/1000 e filtro SV220, ho inseguito pazientemente i fotoni di idrogeno emessi da queste nubi, raccogliendo la loro luce fioca e antica, viaggiatrice per millenni nello spazio, per trasformarla in immagine. Un frammento di galassia che unisce la precisione della scienza alla poesia del cielo.

This one is a bit of a labour of love. A few days' ago, I took my camera outside into my back garden in Scotland and sat on it my star adventurer star tracker and aimed it up to the brightest most recognisable star cluster in our night sky - The Pleiades. With my watchful eye, the system spent four and a half hours gathering ancient photons (444 light years) into my camera. I then carefully stretched and pulled out the faint dust that surrounds this beautiful star cluster. It is no wonder ancient civilisations looked up to this and pondered their place in the cosmos. Thank you for looking.

Here is another shot at the Witch Head Nebula in Orion with Remote Telescope Live.
Original Data from Remote Telescope / Telescope Live. Processed by me, 2023.

Found right in the milky way, the Constellation of Auriga is a large bright hexagonal constellation with it's brightest star being Capella. The stars that make this constellation are 80-to around 3032 Light years from earth!
Bortle 5 Location (my backyard). 60 x 1 minute exposures, f/4. Total integration 1 hour. 20 darks, 40 flats, 40 bias frames.
Zoom in, it's hard to believe the number and stars and the details.
IC 63, also known as the Ghost Nebula or the Ghost of Cassiopeia, was formed as a molecular hydrogen cloud and dust region shaped by the radiation from the nearby star Gamma Cassiopeiae (blue star here). Located 550 light-years away in the constellation Cassiopeia, it is a strikingly powerful image hiding in the cosmos. Here we can see the red hydrogen gas which makes up this nebula.
NB:
This was shot remotely, using Telescope Live. It was edited in Siril and then Photoshop. The process took several hours.
On Saturday evening, the 1st of March 2025, the stars (and planets) aligned in a very literal sense. I have previously captured Mars and Jupiter in my residential area however Venus was too far west (and too low on the horizon) for me to do so then.
I needed a foreground that could accept a huge field of view. This field of view is approximately 220 degrees looking in a southerly direction at the cosmic spectacle that saw seven planets align in our night sky. The planets we can see clearly are Mars (top left), Jupiter (top centre) and Venus (horizon - right). You are probably wondering where the other four planets are? Uranus is a massive planet; it's only a little smaller than Saturn which is already many, many times the size of Earth, however it appears as a tiny dot in our night sky due to it's distance from us and ideally needs a telescope to view it properly. It is present here just below the blue Pleiades star cluster. The others; Neptune, Mercury and Saturn were below the horizon at this point and not imagable.
As well as the planets, this image is full of recognisable constellations, made better known to us through the faint low cloud present during shot taking, they glow bright and colourful. We can see Gemini next to Mars, Orion centrally, also Perseus with the double cluster and Pleiades, as well as Cassiopeia on the far right and others. The Andromeda Galaxy makes an appearance above the horizon on the right. (On mobile tap to see a magnified view).
I took this mosaic using a Nikon Z8 with a state of the art Tamron 35/1.4 prime lens on a Star Adventurer Star Tracker. There are 18 panels that make up the sky, each one is with the following settings: f/1.4, ISO 800 (above dual gain point), and 30s.
The foreground is a separate pano using the same field of view and lined up in post processing. The end result was a 400 megapixel image, which I downsized to 200 to make it a little more manageable. As you can imagine, this picture took many hours of work in the field and processing, so please enjoy and thank you for looking.

Ecco M27 – la celebre Nebulosa Manubrio- come non la avevo mai vista (con il mio telescopio)
In questa ripresa ad alta risoluzione appare quasi come una campanella blu sospesa nel vuoto cosmico.
I dettagli finissimi mettono in luce screziature di rosso e arancio, tracce degli strati di gas ionizzato espulsi da una stella morente.
Questa immagine racconta la poesia della fine stellare trasformata in luce e colore.
Per i più curiosi, questa nebulosa è a circa 1.360 anni luce nella costellazione della Volpetta, ed è una delle nebulose planetarie più studiate e luminose del cielo.
La sua forma complessa è il risultato di venti stellari che hanno modellato le nubi residue, arricchendole di ossigeno, idrogeno e zolfo.
Questa immagine raccoglie 70 minuti di posa attraverso il filtro SVBONY 220 e con con lo SkyWatcher 200/1000

The supermassive blue-white star Deneb lies at a distance of 2,620 light years to Earth. Deneb is the brightest star in the constellation Cygnus (the swan). Deneb's size is estimated to be slightly greater than 200 solar diameters! It is utterly gigantic compared to our star, the sun.
The way in which stars create energy is they convert hydrogen (the most abundent element in the universe) into helium. This is essentially nuclear fusion, and creates a pressure which holds the star up against the opposite force of gravity, trying to crush it back down. This star has exhausted the hydrogen in it's core and expanded to become a supergiant. It will die in a huge explosion which we will easily detect here on Earth. Sitting around this region is vast plumes of hydrogen gas (shown in red). The variation in star colour here is quite beautiful. But what I find more curious than all of this, is there are two exoplanets (planets outwith our solar system) orbiting this star, way out there in space. Just imagine what those worlds could look like. If they are anywhere near to this star they could be strange, violent places influenced by immense gravity and turmoil. If they exist far enough from the star itself, they could even harbour life.
NB - NASA have detected planets around distant stars using the Kepler space telescope. Now obviously, exoplanets do not emit light so there is no possible way to take pictures of them at this vast distance. What Kepler infact does, is monitors the amount of light emited from the star, and detects the tiny,
infinitesimal change in brightness, as the tiny exoplanet crosses between us and the star. Imagine how sensiitive it has to be to discover this.
In questa immagine a largo campo, ripresa dalla città con il mio solito setup, si svelano due oggetti celesti affascinanti e apparentemente vicini solo per prospettiva: la nebulosa a emissione NGC 7635, nota come "Bubble Nebula", e l’ammasso aperto M52.
La Bubble Nebula è una sfera di gas soffiata dalla potente azione del vento stellare di una giovane stella massiccia, che la illumina dall’interno e ne scolpisce le forme. Il contrasto tra la delicata bolla di idrogeno incandescente e le dense nubi circostanti dona alla nebulosa un aspetto tridimensionale unico.
Poco sopra, l’ammasso aperto Messier 52 raccoglie decine di giovani stelle blu, immerse nel ricco campo stellare della costellazione di Cassiopea. Sebbene visivamente vicini, i due oggetti si trovano a distanze diverse: M52 a circa 5.000 anni luce e la Bubble Nebula a circa 7.100 anni luce dalla Terra.
La foto è stata realizzata sotto un cielo cittadino, con pazienza e passione, sfruttando filtri e tecniche di elaborazione per valorizzare i dettagli e i colori di queste meraviglie celesti nonostante l’inquinamento luminoso. Un piccolo angolo di universo che racconta di stelle nascenti, vento stellare e antichi ammassi nel cuore del nostro braccio di spirale galattico.

A 10 milioni di anni luce da noi, nella costellazione della Giraffa, NGC 2403 si distingue per la sua struttura “flocculenta”: al posto delle braccia a spirale ben definite, sfoggia una miriade di nodi di formazione stellare sparsi e luminosi, che le conferiscono un aspetto granuloso e irregolare. Dalla città è un oggetto molto debole: la sua luce, già esile per via della distanza, è ancor più velata dal bagliore dell’inquinamento luminoso, eppure riesce comunque a raggiungerci dopo un viaggio cosmico iniziato quando sulla Terra non esistevano ancora gli esseri umani.
Le galassie sono isole di materia nel vuoto cosmico: splendono le une per le altre, ma restano eternamente separate, come fari lontani in un oceano senza rive.

M94, the Cats eye galaxy is a challenge to image and process as it has a very bright center and an outer ring that is very dim. The inner ring contains a lot of newly formed blue stars and the outer ring is actually a continuation of its spiral arms. This galaxy is still a mystery to astronomers as it doesn't have any dark matter which most all other galaxies have. In other words, all of its mass is accounted for in the stars.

GC 5907, also known as the Splinter Galaxy, might look at first like a simple edge-on spiral, located about 40 million light-years away in the constellation Draco.
However, long exposures reveal a faint grey cloud surrounding it: a stellar arc stretching over 150,000 light-years into space — the remains of a small satellite galaxy, torn apart and absorbed by NGC 5907 more than 4 billion years ago.
A cosmic scar, quietly telling the story of how massive galaxies like this one — and even our Milky Way — formed: by merging with smaller companions.
This image was captured over the past six months in multiple remote sessions from Spain, with a total of over 12 hours of integration.

Buenas, les comparto una sesión cortita de 4hs de integración que hice de la Nebulosa Gabriela Mistral, NGC 3324. Me encanta esta nebulosa tan característica y no tenia ninguna foto con varias horas de integracion asi que al tener que esperar hasta la 1 para tirarle a la nebulosa huevo de dragon, aproveche para tirarle y ver que salía. También se puede ver el cúmulo estelar NGC 3293. Este es un cúmulo abierto compuesto por estrellas jóvenes y calientes, muchas de ellas de tipo espectral B, que brillan con intensidad en colores azulados o blancos.
La nebulosa Gabriela Mistral recibe su nombre porque su forma, vista desde ciertas perspectivas, recuerda al perfil de la poeta chilena Gabriela Mistral. Esta semejanza inspiró su apodo, aunque su denominación oficial es NGC 3324. Se encuentra en la constelación de Carina y forma parte del complejo de nebulosas que rodea a la Nebulosa de Eta Carinae.

SH2-115 & SH2-116 – Les joyaux discrets du Cygne 🌌 🇫🇷
Située dans la constellation du Cygne, Sharpless (SH) 2-115 est une vaste nébuleuse en émission à environ 7 500 années-lumière. Ce nuage d’hydrogène ionisé brille principalement en Hα, excité par les vents stellaires puissants et la radiation d’étoiles massives jeunes. Sa structure complexe mêle zones brillantes et filaments diffus, se détachant sur un fond riche en poussières interstellaires.
En dessous, on distingue Sharpless (SH) 2-116, également connue sous le nom d’Abell 71. Longtemps considérée comme une nébuleuse planétaire, il s’agit en réalité d’une région H II, probablement en interaction avec un nuage moléculaire voisin. En palette SHO, sa teinte bleutée révèle une forte émission en O III, contrastant joliment avec les nuances cuivrées du soufre et de l’hydrogène.
