Située dans la constellation du Triangle (Triangulum) à 2,5 millions d'a.l. de la Terre, la nébuleuse en émission du Triangle NGC 604, avec un diamètre de 1500 a.l., soit 40 fois la taille de la nébuleuse d'Orion, est 6300 fois plus lumineuse que celle-ci, si elle se trouvait à la même distance (1 350 al) et surpasserait l'éclat de Vénus. Comme toutes les nébuleuses en émission, son gaz est ionisé par un amas d'étoiles massives en son cœur (cf. wikipédia).

This composite color infrared image of the center of our Milky Way galaxy reveals a new population of massive stars and new details in complex structures in the hot ionized gas swirling around the central 300 light-years.
A new finding is that astronomers now see that the massive stars are not confined to one of the three known clusters of massive stars in the Galactic Center, known as the Central cluster, the Arches cluster, and the Quintuplet cluster. These three clusters are easily seen as tight concentrations of bright, massive stars in the NICMOS image.
This view combines the sharp imaging of the Hubble Space Telescope's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) with color imagery from a previous Spitzer Space Telescope survey done with its Infrared Astronomy Camera (IRAC).
mosaic image represents the largest piece of sky ever mapped for one NICMOS observing program. It was combined with a full-color Spitzer image to yield a color composite of the nuclear region
The NICMOS mosaic required 144 Hubble orbits to make 2,304 science exposures. It was taken between February 22 and June 5, 2008.

This is M51, the Whirlpool Galaxy, seen with it's companion galaxy.
NASA’s Hubble Space Telescope spacecraft was built by Lockheed Missiles Space Corporation (now Lockheed Martin) in its Sunnyvale, California facility. Since the 1990 launch, Lockheed Martin personnel located at NASA's Goddard Space Flight Center, have helped NASA manage the day-to-day spacecraft operations of the telescope, and provided preparation and training for the telescope’s many servicing missions.
La galaxie NGC 1566 est une spirale intermédiaire située approximativement à 40 millions a.l. de la Terre dans la constellation de la Dorade (Dorado, en 1603, l'astronome baptisa beaucoup de constellations du ciel austral de noms d'animaux marins comme les Anciens l'avaient déjà fait) qui contient le Grand Nuage de Magellan dans sa partie sud. Ses bras spiraux sont magnifiquement symétriques.
Elle se classe dans la catégorie des galaxies de Seyfert (10 % des galaxies) où elle est la deuxième la plus brillante après M 77. Les centres des galaxies de Seyfert sont caractérisées par un noyau ici petit mais extrêmement brillant, autant que la galaxie entière, et par un spectre présentant des raies d'émission également très brillantes pour l'hydrogène, l'hélium, l'azote et l'oxygène.
Ces raies présentent un fort effet Doppler correspondant à des vitesses de l'ordre de 500 à 4 000 km/s, anormalement élevées près du noyau. Elles indiquent notamment que ce dernier est potentiellement en orbite autour d'un trou noir massif, voire supermassif, ayant des millions de fois la masse du Soleil (cf. ESA Hubble et NASA).

This luminescent image features multiple galaxies, perhaps most noticeably LEDA 58109, the lone galaxy in the upper right. LEDA 58109 is flanked by two further galactic objects to its lower left — an active galactic nucleus (AGN) called SDSS J162558.14+435746.4 that partially obscures the galaxy SDSS J162557.25+435743.5, which appears to poke out to the right behind the AGN. Galaxy classification is sometimes presented as something of a dichotomy: spiral and elliptical. However, the diversity of galaxies in this image alone highlights the complex web of galaxy classifications that exist, including galaxies that house extremely luminous AGNs at their cores, and galaxies whose shapes defy the classification of either spiral or elliptical. The sample of galaxies here also illustrates the wide variety of names that galaxies have: some relatively short, like LEDA 58109, and some very long and challenging to remember, such as the two galaxies to the left. This is due to the variety of cataloguing systems that chart the celestial objects in the night sky. No one catalogue is exhaustive, and they cover overlapping regions of the sky, so that many galaxies belong to several different catalogues. For example, the galaxy on the right is LEDA 58109 in the LEDA galaxy database, but is also known as MCG+07-34-030 in the MCG galaxy catalogue, and SDSS J162551.50+435747.5 in the SDSS galaxy catalogue — the same catalogue that also lists the two galaxies to the left.
Caldwell 58, also known as NGC 2360 or Caroline’s Cluster, was discovered by and named after the German astronomer Caroline Herschel in 1783. The younger sister of famed astronomer William Herschel, Caroline was the first woman to win the prestigious Gold Medal of the Royal Astronomical Society. She earned this award for her work verifying her brother’s astronomical observations and compiling a catalog of nebulae to aid other astronomers.
Caldwell 58 is an open cluster — a group of stars loosely bound together by gravity. It is located in the constellation Canis Major, roughly 3,700 light-years from Earth. The cluster has an apparent magnitude of 7.2 and can be spotted with a pair of binoculars in dark, moonless skies.
Caldwell 58 is most easily observed during the Northern Hemisphere’s winter and the Southern Hemisphere’s summer.
Astronomers used Hubble to study white dwarfs in Caldwell 58 and better understand the age of our galaxy. After a Sun-like star has exhausted its supply of nuclear fuel and ejected its outer layers of gas, what is left behind is the hot core of the star — a white dwarf. These objects cool over a period of billions of years and are some of the oldest stars in our galaxy. Some white dwarfs pulse regularly as they cool. The time between these pulsations changes over the white dwarf’s lifetime, so the time between pulses can be used to estimate how quickly the white dwarf is cooling, and thus how long it has been cooling. This information is useful to astronomers because it means pulsating white dwarfs can be used as chronometers, or “clocks,” that constrain the age of our galaxy. These observations of Caldwell 58 were made with Hubble’s Advanced Camera for Surveys to help astronomers calibrate white-dwarf chronometers.

NGC 4522 is an example of a spiral galaxy that is currently being stripped of its gas content. The galaxy is part of the Virgo galaxy cluster and its rapid motion within the cluster results in strong winds across the galaxy as the gas within is left behind. Scientists estimate that the galaxy is moving at more than 10 million kilometers per hour. The galaxy is located some 60 million light-years away from Earth. (Hubble site)

Hubble’s payload computer, which controls and coordinates the observatory’s onboard science instruments, halted suddenly on June 13. When the main computer failed to receive a signal from the payload computer, it automatically placed Hubble’s science instruments into safe mode. That meant the telescope would no longer be doing science while mission specialists analyzed the situation.
In response to the anomaly, NASA began a switch to backup spacecraft hardware on Hubble in response to an ongoing problem with its payload computer. This was a multi-day event.
Science observations restarted the afternoon of Saturday, July 17.

I think they are Ha,OIII an SII...I just looked at all the (100) images available as previews and picked them based on my recall of my own results
Its confusing in there....(!)
After all my recent worry about my results lately (disappointing) it was comforting somehow to work on this image....(!)
Other than brighter objects, I am still struggling to get good results from a city location....even with extreme NB filters.
Taking 30 minute exposures with a low QE camera is frustrating.I am already working at f/5...not really interested in Hyperstar etc...
Running out of options...
Was looking at higher QE camera's today...FLI mostly...
They are 10 to 15,000 $$...(more for super large chips)
Is it worth it...?
Just wondering..........................................In a bit of a funk today about the whole situation.
Obviously the first thing I need to do is get off my butt and try these same exposures at a darker site,before wasting $ on a camera.

NGC 1672 is a barred spiral galaxy located in the constellation Dorodo. As seen in this image taken by Hubble’s Advanced Camera for Surveys, dust lanes extend away from the galaxy's nucleus and follow the inner edges of the spiral arms. Clusters of hot, young, blue stars form along the spiral arms and ionize surrounding clouds of hydrogen gas that glow red. Delicate curtains of dust partially obscure and redden the light of the stars behind them by scattering blue light.
Astronomers believe that barred spirals have a unique mechanism that channels gas from the disk inward toward the nucleus. This allows the bar portion of the galaxy to serve as an area of new star generation.
NGC 1672 is also classified as a Seyfert galaxy, a subset of galaxies with active nuclei. The energy output of these nuclei, powered by accretion onto supermassive black holes, can sometimes outshine their host galaxies.

This Picture of the Week shows Arp 230, also known as IC 51, observed by the NASA/ESA Hubble Space Telescope. Arp 230 is a galaxy of an uncommon or peculiar shape, and is therefore part of the Atlas of Peculiar Galaxies produced by Halton Arp. Its irregular shape is thought to be the result of a violent collision with another galaxy sometime in the past. The collision could also be held responsible for the formation of the galaxy’s polar ring. The outer ring surrounding the galaxy consists of gas and stars and rotates over the poles of the galaxy. It is thought that the orbit of the smaller of the two galaxies that created Arp 230 was perpendicular to the disc of the second, larger galaxy when they collided. In the process of merging the smaller galaxy would have been ripped apart and may have formed the polar ring structure astronomers can observe today. Arp 230 is quite small for a lenticular galaxy, so the two original galaxies forming it must both have been smaller than the Milky Way. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by flickr user Det58. Links Atlas of Peculiar Galaxies

A view of the central region of the Carina Nebula where a maelstrom of star birth — and death — is taking place. This image is a mosaic of the Carina Nebula assembled from frames taken with Hubble's Advanced Camera for Surveys. The Hubble images were taken in the light of neutral hydrogen during March and July 2005. Color information was added with data taken in December 2001 and March 2003 at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.
Dans la constellation du Poisson volant (Volans) à 67 millions d'a.l. de la Terre, la galaxie spirale intermédiaire NGC 2442 a l'un de ses bras spiraux étroitement replié sur lui-même, tandis que l'autre se déploie loin du bulbe. Cette déformation provient de la rencontre avec une autre galaxie (cf. site Hubble).

La galaxie spirale NGC 3596 (Hubble) est située à 90 millions d'années-lumière de la Terre dans la constellation du Lion (LEO). Elle est ici visible avec six longueurs d'onde lumineuses différentes et apparaît presque parfaitement de face vue de la Terre, mettant en valeur les bras spiraux soigneusement enroulés. Ces bras brillants abritent des concentrations d'étoiles, de gaz et de poussière marquant la zone où la formation stellaire est la plus active, illustrée par les régions de formation d'étoiles roses brillantes et les jeunes étoiles bleues qui en dessinent les bras.
Qu'est-ce qui provoque la formation de ces bras spiraux ? Déjà en partie parce que les galaxies spirales sont très diverses, certaines ayant des bras spiraux clairsemés, tandis que d'autres sont plus ou moins denses et plumeux. Parfois, elles présentent même des barres proéminentes en leur centre, tandis que d'autres ont des noyaux compacts et circulaires. Si certaines ont des voisins proches, d'autres sont isolées.
Leur enroulement pose aussi problème. Si les bras spiraux sont des structures cohérentes, leurs bras s'enrouleraient de plus en plus serrés à mesure que la galaxie tourne, jusqu'à disparaître. Aujourd'hui, les chercheurs pensent que les bras spiraux représentent un motif de zones de forte et de faible densité, plutôt qu'une structure physique. Lorsque les étoiles, le gaz et la poussière orbitent dans leur disque, ils entrent et sortent des bras spiraux. Comme dans un embouteillage, ces matériaux ralentissent et s'agglutinent lorsqu'ils entrent dans un bras spiral, avant d'en émerger et de poursuivre leur voyage à travers la galaxie (cf. texte : Agence spatiale européenne et image : ESA/Hubble & NASA, D. Thilker).

Dans la constellation d'Orion, à 5 000 a.l. de la Terre, la nébuleuse planétaire NGC 2022 est un vaste globe de gaz dans l’espace, chassé par une étoile vieillissante, visible au centre et brillante à travers les gaz. Lorsque les étoiles comme le Soleil grandissent en âge, elles se dilatent, rougeoient et commencent alors à perdre leurs couches extérieures de matière. Plus de la moitié de la masse d’une telle étoile peut être ainsi libérée, formant une coquille de gaz, le noyau de l’étoile rétrécissant et devenant plus chaud, la lumière ultraviolette émise faisant briller les gaz expulsés. Le nom de nébuleuse planétaire n’a rien à voir avec les planètes, mais dérive de l’aspect arrondi et semblable à une planète qu'avaient ces objets dans les premiers télescopes (cf. site Hubble).
