Right, I'm officially sick to death of Andromeda! This is now 16 hours of varying sub-lengths and ISO settings, and I've reached the point where my skies are going to yield no more. Quite depressing to think that 16 hours here produces the same result as perhaps an hour under dark skies - so this is my final attempt ;) (Wrong!). Better processing than the last shocking effort I think - a little more subtle, and some fainter detail evident (and some detail less evident as the contrast has been turned down a bit!)
Having spent a fortnight thinking about very little else, I can now get on with my life :)

Taken with a TMB92L, Canon T3i DSLR, and Celestron CG-4 mount. Consists of 38 light and 29 dark frames, each a 35-second exposure at ISO 800, stacked in DeepSkyStacker and processed in Photoshop.
This is the Rho Ophiuchi region shot with my Nikon D7000 and Rokinon 85mm f1.4 lens on an iOptron Skytracker mount. This is the first image I've done with the Optolong UHC filter as well, which added a tremendous amount of signal to the red channel.
I did two sets of exposures, one with the filter in and one without, each set is ISO 400 and f2.5, 2x 4 minutes, 2x 2 minutes, and 2x 1 minute exposures. Stacked with Deep Sky Stacker and edited with PixInsight and Photoshop. Shot from a Bortle 4/5 zone at Rockport Reservoir, Utah.
M22 (NGC 6656) is a rich globular cluster that is visible in the dense star fields of Sagittarius. If you took pictures of it throughout the night, you could look for RR Lyrae variables to measure the distance to it. This is the method Harlow Shapley used -- based on Henrietta Leavitt's period-luminosity analysis -- to measure the size of the Milky Way Galaxy and our position within it. The bright star at the lower right is 24 Sgr.
From 16 90s exposures preprocessed in Nebulosity, stacked and initially processed in PixInsight, with final touches in PS CS 5.1. Taken with a Celestron Edge HD at f/2.3 with Hyperstar and an Atik 314L+ color CCD.

For the first time I can remember, we had an entire week of consecutive clear nights. No option but to make the most of it. So despite it being low on the northern horizon, I pointed my smaller refractor telescope at a well-known part of Cassiopeia.
There's a lot happening in this region of space. All the rusty orange-red is Hydrogen-alpha emission nebulosity; the bright blue is Oxygen-III emission nebula. At the bottom is the well-known Lobster-Claw nebula (Sh2-157); upper left is the Bubble Nebula (Sh2-162 or NGC 7635) - a giant molecular cloud being excited and pushed away by its central star; toward the upper right is a small bright emission nebula NGC7538 in neighbouring Cepheus surrounded by the Ha haze of Sh2-161.
I accumulated a total integration of 19 hours using a mixture of Optolong L-eNhance and IDAS NBZ dual-narrowband filters for the nebulae and Neodymium for the stars (so the colours are very realistic). In the process, the image became not just about the obvious bright glowing bits but also about the subtle veins of dark nebulae running through the Bubble and the large Y-shaped expanse in the upper third.
Whilst exploring in great detail, I stumbled across a rather fuzzy looking star just above the centre of the image, left of the top "claw" - with some research, it transpires this is HH-170, the first time I've spotted a HerbigâHaro object (a tiny reflection nebula, jets of partially ionized gas interacting with more gas and dust surrounding newly formed stars).
It was sufficiently low on the northern horizon that I had to abandon shooting for an hour each night while the neighbours' house got out the way. Shooting at near-full moon through the thickest part of the atmosphere made for a lot of light pollution which took some work removing in post. I look forward to reshooting throughout the season.
Much of the work with stacking and extracting Ha and OIII channels and fixing the star shapes and colours happened in PixInsight, but the final combination was performed in Affinity Photo for a dynamic precise control of how far the OIII intersected overlapping the Ha signal, most notable in the Lobster Claw.
Dans la constellation du cygne, NGC 7000 est l’une des plus vastes nébuleuses du ciel boréal : elle représente dans le ciel une surface équivalente à plus de 4 pleine Lune (quasiment 6° au total).

This is a two panel mosaic of the remains of a supernova that occured in the constellation Cygnus. The full complex of the Veil Nebula is significantly larger than this, but this could serve as the beginning of a mosaic to get the full web of dust and energized gas.
Each panel is a stack of 5 min exposures with an Edge HD 925 at f/2.3 with Hyperstar and an Atik 314L+ one-shot color CCD camera. Images were preprocessed in Nebulosity, then registered and stacked in PixInsight. PixInsight was also used to assemeble the mosaic and for further processing. Final touches in PS CS 5.1.
This is roughly centered on the star 52 Cygni (bright star at center), whose coordinates are:

Not my favourite subject, but not a lot up there at the moment, and we had a couple of clear nights :)
Five sessions between 1-29 April 2013 - total 10 hours 38 minutes. I don't think giving the total exposure is of much help to anyone really, as the result depends on so many factors, not least the quality of your skies (pretty low in my case). But it at least demonstrates how much effort has been expended :)
And the stars are almost round :)

One of my fist short exposure learning/test Astro-images (photographed close to the city).
A deep sky wide field astro-photo of Omega Centauri (NGC 5139), a globular cluster in the constellation of Centaurus. Located at a distance of 15,800 light-years, it is the largest globular cluster in the Milky Way Galaxy (at a diameter of roughly 150 light-years).
To give an indication of distance, light travels about 10 trillion kilometers or 6 trillion miles in a year. The Omega Centauri globular cluster is estimated to contain approximately 10 million stars and a total mass equivalent to 4 million solar masses (1 solar mass is equal to the mass of the Sun, weighing in at about 2 Nonillion kilograms).
Globular Clusters were described by Carl Sagan like a "swarm of bees". In this case it is 10 Million suns in a dense cluster.

Messier 45 - Open Cluster M45, type ‘b’ in Taurus - Coordinates: RA 3h 47m 24s | Dec +24° 7′ 0″, Distance to earth: 444.2 light years, Radius: 17.5 light years, Magnitude 1.6, Constellation of Taurus, Color: hot blue. There are references to the Pleiades in the Odyssey, the Bible, and the Quran, and it is also revered in Hindu mythology. Mentioned by Homer about 750 B.C., by biblical Amos about 750 B.C., and by Hesiod about 700 B.C. The Pleiades, also known as Messier 45 (M45), are among those objects which are known since the earliest times. At least 6 member stars are visible to the naked eye. At the same time, under moderate conditions, this number increases to 9, and under clear dark skies jumps up to more than a dozen (Vehrenberg, in his Atlas of Deep Sky Splendors, mentions that in 1579, well before the invention of the telescope, astronomer Moestlin has correctly drawn 11 Pleiades stars, while Kepler quotes observations of up to 14).
The Pleiades also carry the name "Seven Sisters"; according to Greek mythology, the Pleiades are the seven daughters of the “father” Titan Atlas "mother" Oceanid Pleione: Alcyone, Asterope (a double star, also sometimes called Sterope), Electra, Maia, Merope, Taygeta and Celaeno. It was said that after Atlas was tasked to carry the heavens on his shoulders, the hunter Orion began to pursue the Pleiades. To protect them Zeus transformed them into doves, and then into constellations, to comfort their father. The constellation of Orion still pursues the Pleiades across the night sky. This pursuit is apparent in a timelapse video of these two objects.
In Japan, the Pleiades are called “Subaru", and the car company of the same name uses the Pleiades as their company logo.
The Persian name is "Soraya", after which the former Iranian empress was named. Old European (e.g., English and German) names indicate they were once compared to a "Hen with Chicks". Other cultures tell more and other lore of this naked-eye star cluster. Ancient Greek astronomers Eudoxus of Knidos (c. 403-350 BC) and Aratos of Soloi (c. 310-245 BC), in his Phainomaina (c. 270 BC), listed them as their own constellation: The Clusterers. Admiral Smyth also refers to this in his Bedford Catalog.
The Pleiades is one of the best-known star clusters in the entire sky. It is easily visible to the naked eye on Winter evenings from the Northern Hemisphere. Located in the constellation of Taurus, the Pleiades forms a tiny dipper-shaped asterism in the shoulder of the Bull.
The Pleiades nebulae are blue-colored, which indicates that they are reflection nebulae, reflecting the light of the bright stars situated near (or within) them. The brightest of these nebulae, that around Merope, was discovered on October 19, 1859, by Ernst Wilhelm Leberecht (Wilhelm) Tempel at Venice (Italy) with a 4-inch refractor; it is included in the NGC as NGC 1435. The nebulae around Alcyone, Electra, Celaeno and Taygeta were found in photographs in the later 1880s. The first Astro cameras revealed the full complexity of the Pleiades nebulae, e.g. by that of the brother's Henry in Paris and Isaac Roberts in England, between 1885 and 1888. In 1890, E.E. Barnard discovered a starlike concentration of nebulous matter very close to Merope, which found its way into the IC as IC 349. The analysis of the spectra of the Pleiades nebulae by Vesto M. Slipher in 1912 revealed their nature as reflection nebulae, as their spectra are exact copies of the spectra of the stars illuminating them.
Physically, the reflection nebula is probably part of the dust in a molecular cloud, unrelated to the Pleiades cluster, which happens to cross the cluster's way. It is not a remainder of the nebula from which the cluster once formed, as can be seen from the fact that the nebula and cluster have different radial velocities, crossing each other with a relative velocity of 6.8 mps, or 11 km/sec. Even with the naked eye and under modest conditions, the Pleiades are rather easily found, roughly 10 degrees north-west of the bright red-giant star Aldebaran (87 Alpha Tauri, mag 0.9, spectral type K5 III). This is a very appealing spectacle, especially for amateurs with less expensive equipment (actually, you can observe it with the naked eye, but even the smallest binoculars or telescopes will increase observing pleasure.

Las nebulosas son tan famosas quizá porque se identifican con formas familiares, al igual que los gatos lo son quizá porque se meten en problemas. Sin embargo, no se conoce ningún gato que pudiera crear la enorme nebulosa Pata de Gato visible en Scorpius. La Pata de Gato se encuentra a 5.500 años luz de distancia y es una nebulosa de emisión con un color rojo que proviene de la gran abundancia de átomos de hidrógeno ionizado. Conocida también como la nebulosa Zarpa de Oso o NGC 6334, contiene estrellas de casi diez veces la masa del Sol que han nacido en este lugar durante los últimos millones de años.
La imagen es una fotografía de campo profundo de la nebulosa Pata de Gato, fue capturada en los oscuros cielos del Cajon del Maipo el pasado 12/05/2019.

This image, taken over 3 nights, shows M42 along with 2 other nebulae, De Mairan’s nebula (M43) and The Running Man nebula (Sh2-279). De Mairan’s nebula is located just off to the centre left of the image, separated from M42 by dark dust lanes. The Running Man nebula can be seen towards the top of the image as an area of blue nebulosity (a reflection nebula), with the ‘Running Man’ as a silhouette in the middle.
First clear moonless night since 18 September - I feel so blessed! :)
I use the term "clear" in its loosest possible sense, as it was Guy Fawkes Night here and the smoke from bonfires and fireworks certainly didn't assist much (why do we celebrate someone NOT blowing up Parliament?!). Given the conditions, I'm quite pleased with this, but I'll give it more time if we get another clear night before it disappears :)
Always looks like a galaxy that's just got out of bed and needs combing to me :)

Through gaps in the cloud tonight I managed 27 subs of this. Never done it before so thought I should. Not much to say about it really, being a cluster (or two), but here's a bit from wiki: The Double Cluster is the common name for the "naked-eye" (huh!) open clusters NGC 869 and NGC 884, which are close together in the constellation Perseus. NGC 869 and NGC 884 both lie at a distance of 7500 light years.There are more than 300 blue-white super-giant stars in each of the clusters (but not in my picture!)

I've never used drizzle in DSS before, but I thought I'd give it a crack on this as the galaxies are so tiny. Seems to have yielded some improvement, particularly in M66 - the more interesting of the trio.

NGC 2264 a.k.a. Christmas Tree Cluster
…………………………..................................
Before going into details, the catalog number NGC 2264 does not refer to a single deep sky object, but to four, in the attached image only three can be seen, namely:
- Cone Nebula, an emission nebula that can be seen at the top of the image, being easy to find due to the shape of the nebula, the shape that gave it its name.
- The Christmas Tree Cluster, which stretches over the area between Cone Nebula and the bright star in the center.
- Fox Fur Nebula, which can be seen in the lower left, so named because of the apparent texture that this nebula has in that area.
The 4th DSO that completes the list of cosmic objects that belongs to NGC2264 and which is unfortunately missing from the attached image, is a small cluster, called Snowflake ( of course 😊)
As general information, NGC2264 is about 2700 light-years from us, in the constellation Monoceros, and was discovered by William Herschel almost 250 years ago, on December 26, 1785. Being an emission nebula, NGC2264 is formed mainly from cosmic dust and gases, hydrogen being the most common. That blue "cloud" is just a patch of cosmic dust illuminated by the central star, easily visible.

M93 (NGC 2447) is an open cluster in Puppis. It's one of the more southerly Messier objects, so there's a shorter window for when I can shoot it from my location in Long Beach. These were taken on 2023-02-15 -- a rare clear night this winter.
I used a Celestron Edge HD 925 with Hyperstar at focal length 535 mm and an Atik 414-EX monochrome camera with Optolong CCD LRGB filters to get the following exposures:
L: 181 10 s exposures
R: 41 30 s exposures

After a few cloudy and foggy nights, I finally had the opportunity to get to know my new digital telescope “ZWO Seestar S50 Smart Telescope” better and try it out with excellent visibility.
The constellation of Orion is one of the most beautiful and striking winter constellations. It contains a star-forming region and many interesting celestial objects. The most famous are probably the Horsehead Nebula and the Orion Nebula.

Tipo: Nebulosa de emissão
Distância: 5.000 anos-luz
Constelação: Cisne [1]
Estrelas massivas têm vidas curtas e espetaculares. Esta imagem revela detalhes dramáticos da Nebulosa Crescente, uma gigantesca concha gasosa criada por fortes ventos que sopram da estrela central catalogada como HD 192163 (também conhecida como WR 136). [2]
Depois de apenas 4,5 milhões de anos (um milésimo da vida do nosso Sol), a estrela HD 192163 iniciou uma corrida precipitada em direção à formação de uma catastrófica supernova. Primeiro a estrela expandiu-se enormemente para se tornar uma gigante vermelha e ejetou suas camadas externas a uma velocidade de aproximadamente 32000 km/h. Duzentos mil anos depois, tempo que equivale a um piscar de olhos na vida de uma estrela normal, a intensa radiação da camada externa exposta e quente da estrela começou a empurrar o gás para longe a velocidades superiores a 4.8 milhões de km/h! [2]
Quando este "vento estelar" de alta velocidade atingiu o vento gigante vermelho mais lento, formou-se uma densa concha. Na imagem, esta concha apresenta-se na cor vermelha. A força da colisão criou duas ondas de choque: uma que se moveu para fora da casca densa para criar a estrutura filamentar azul, e uma que se moveu para dentro para produzir uma bolha de gás emissor de raio X de milhões de graus Celsius (não é vista nos comprimentos de ondas registrados). A emissão de raios X mais brilhante está próxima da parte mais densa do reservatório de gás comprimido, indicando que o gás quente está evaporando a matéria da casca. A estrela massiva HD 192183 que produziu a nebulosa aparece como o ponto brilhante no centro da imagem. [2]
A estrela HD 192163 provavelmente explodirá como uma supernova em cerca de cem mil anos. Imagens assim permitem aos astrônomos determinar a massa, energia e composição da camada gasosa ao redor desta estrela pré-supernova. Uma compreensão de tais ambientes fornece dados importantes para interpretar observações de supernovas e seus remanescentes. [2]

Name: NGC 6888, Caldwell 27, Sharpless 105
Type: Emission Nebula
Distance: 5,000 light-years
Constellation: Cygnus [1]
Massive stars lead short, spectacular lives. This image reveals dramatic details of the Crescent Nebula, a giant gaseous shell created by powerful winds blowing from the massive star HD 192163 (a.k.a. WR 136, the star is in the center of image). [2]
After only 4.5 million years (one-thousandth the age of the Sun), HD 192163 began its headlong rush toward a supernova catastrophe. First it expanded enormously to become a red giant and ejected its outer layers at about 20,000 miles per hour. Two hundred thousand years later - a blink of the eye in the life of a normal star - the intense radiation from the exposed hot, inner layer of the star began pushing gas away at speeds in excess of 3 million miles per hour! [2]
When this high speed "stellar wind" rammed into the slower red giant wind, a dense shell was formed. In the image, a portion of the shell is shown in red. The force of the collision created two shock waves: one that moved outward from the dense shell to create the blue filamentary structure, and one that moved inward to produce a bubble of million degree Celsius X-ray emitting gas (not viewed on the spectrum eletromagnetic registered). The brightest X-ray emission is near the densest part of the compressed shell of gas, indicating that the hot gas is evaporating matter from the shell. The massive star HD 192183 that has produced the nebula appears as the bright dot at the center of the image. [2]
HD 192163 will likely explode as a supernova in about a hundred thousand years. This image enables astronomers to determine the mass, energy, and composition of the gaseous shell around this pre-supernova star. An understanding of such environments provides important data for interpreting observations of supernovas and their remnants. [2]

"Piggybacking" my camera to the optical tube assembly of my refractor telescope while the scope is set to follow the movement of the night sky allows the camera to record long periods of time in the night sky without creating star trails. It was something i wanted to try for awhile however never attempted. This weekend i packed up my astronomy equipment along with my camera gear in the car and headed for the mountains to darker skies. My goal was to practice deep sky imaging while gazing which required my astronomy tools. My arsenal is modest most would say, an Orion 120mm skyview pro refractor with electronic tracking equipment(GOTO) on a german equatorial mount. My telescope is great, sharp and beautiful views with a 1000mm focal length at F8 and ED glass. technical stuff aside it decided to practice by pointing the camera toward different regions of the milky way and see what detail is revealed. I was quite impressed with the results.In this image you see the summer triangle region of the milky way cropped just above the constellation scutum and the star Altair. the cygnus region of the milky way is striking in this image. You can begin to see the pink colors ot the North American Nebula near the star Deneb. this is a composite of 5 images shot at different lengths of exposure and settings blended together in post processing using a manual stacking process.

This was shot from my backyard in Long Beach, CA. Whenever I target deep sky objects from my light polluted home skies, there are always significant gradients to deal with in the final image. With this particular data, that is made worse by the image being a mosaic. I shot this in March 2017, and over the past two years, I think I learned enough to minimize their effect. M53 is in the upper right, and NGC 5053 is in the lower left.
Each panel is a stack of 120 s exposures shot with a Celestron Edge HD 9.25" at f/2.3 with Hyperstar and an Atik 314L+ color CCD. Initial pre-processing in Nebulosity, stacking and initial processing in PixInsight; final processing in PS CS 5.1.

Continuing our seemingly never ending series of clear nights, this is the North America Nebula, featuring The Wall. Noisy, but done in one session as the dark isn't long enough at this time of the year, and I don't have the energy to do another session. Also the sensor was running at 31c, which is a bit warm :)

I have the cluster bug :)
Spent a good amount of time recently testing a bit of kit that effectively converts my EQ5 to a Goto, and now using EQMOD in conjunction with PHD for guiding. Working well, and for £90 (and in the true spirit of budgetastro) I'm more than pleased :)
Found this cluster while I was zipping around the heavens playing with the Goto, and fell in love with it. M35, aka NGC 2168 in the foreground, is about 2.8K light years away, quite young at 150m years (hence the blue stars) and contains about 2500 stars. NGC 2158 (above right of M35) is about 10K lights years away and is ten times older than M35 (hence the orange stars). It contains many more stars than M35 but in roughly the same volume of space (30 ly wide), so looks more like a globular cluster. Nice contrast :)

當彗星遇上深空天體
近年彗星拍攝變得熱鬧，尤其是近兩年的 PANSTARRS 及 LOVEJOY 是十分容易捕足得到的，還能夠與在不同的深空天體掠過，令萬年不變的深空天體畫面多了一點變化。今年初就是 LOVEJOY C/2014 Q2 的熱鬧拍攝日子，剛好在昴宿星團與加州星雲附近飛過，用上廣角鏡頭也能輕易拍攝，尾巴長度數以十萬公里以上，十分壯觀。
今年另一顆彗星 CATALINA C/2013 US10 將會是另一個熱門目標，12 月至 1 月期間將可達 5 至 6 等亮度，1 月中更會跨過 M101 星系，令 M101 變得不再狐獨。喜歡拍攝深空的你，相信不會錯過吧！

On my last nightscape photography trip to Taralga, Australia, I was able to get some shots of the Milky Way’s core region not long before it set over the southwestern horizon. Once that favoured area of the heavens was–literally–out of the picture, I turned my attention to photographing some of the other galaxies that are visible here in the Southern Hemisphere.
I recently posted one of those images, containing the Large and Small Magellanic Clouds, which are dwarf galaxies travelling through space with our own Milky Way galaxy. As well as those relatively-close massive collections of stars, planets, dust, gas and asteroids–and the odd black hole or two–there are a few other “islands universes” that are visible to naked-eye observers. I photographed two of these, the Andromeda Galaxy and the Triangulum Galaxy, as they hung low in the northern sky.
Known in astronomical catalogues as “M31”, the Andromeda Galaxy sits around 2.5 million light-years from our position in the “Local Group” of galaxies. M31 is visible in my photo as a fuzzy-yet-distinct bright disc mid-way down the shot, and about one third in from the left. If you look up to the right, in the one o’clock direction from Andromeda, there’s a much smaller blur of light showing the position of the Triangulum Galaxy. Aka “M33”, this galaxy is nearly 3 million light-years away in space. The Milky Way, M31 and M33 are the three largest galaxies, respectively, in the Local Group.
This image was stacked from ten single-frame photos, each of which I shot with my Canon EOS 6D Mk II camera, a Yongnuo 50mm f/1.4 lens @ f/1.4, using an exposure time of 8 seconds @ ISO 6400.
