The cropped image at left was taken with a Nikon d7100, Nikkor 180mm f/2.8 @ f/2.8, exp 173x90s (or 4.3 hours integrated time), iso 3200, fixed comet and no stars; the right image is its invert. All images post-processed with PixInsight.

Il Quintetto di Stephan è un gruppo di 5 galassie nella costellazione di Pegaso, con magnitudine apparente tra 12.6 e 13.9; venne scoperto nel 1877 dall'astronomo francese Édouard Stephan all'osservatorio di Marsiglia.

Dall'immagine è evidente l'interazione tra le 5 galassie: in realtà dall'analisi dei redshifts è emerso che la galassia azzurra sulla destra - catalogata come NGC 7320 - si troverebbe ad una distanza di 32 milioni di anni luce, mentre le altre quattro galassie si troverebbero ad una distanza compresa tra i 280 e 340 milioni di anni luce.

NGC 7320 apparirebbe quindi all'interno del Quintetto solo per un effetto di prospettiva.

Su tutta l'immagine è visibile una debole nebulosità biancastra di poco più luminosa del fondo cielo: si tratta della IFN (Integrated Flux Nebula), appartenente alla nostra Galassia.

----------

Stephan's Quintet is a group of five galaxies in the constellation Pegasus, with apparent magnitudes between 12.6 and 13.9; it was discovered in 1877 by the French astronomer Édouard Stephan at the Marseille Observatory (France). The Stephan Quintet galaxies are not really connected to each other: according to redshift values measured, the blue galaxy on the right - named NGC 7320 - could be 32 million light-years away from us, while the other four are at distances between 280 and 340 million light-years. NGC 7320 would therefore appear inside the Quintet only as a matter of perspective.

On all the image it is visible a faint nebulosity, slightly brighter that the sky background: it is the IFN (Integrated Flux Nebula), belonging to our galaxy.

This data has been sitting on my desktop for a couple of months irritating me, and as the run of terrible weather continues I couldn't resist *another* re-process. The Met Office incidentally predicts the cloudy wet summers could go on for as long as another 10 years!!!

I made good use of the new TGVDenoise process on the luminance channel, the rest was standard processing with a very selective high pass filter in CS5 to finish off.

Here's hoping the weather improves and I don't have to re-proces this again!!

This dark nebula belongs to the head of the Lion Nebula or Sh2-132.

Amazing fight on this complex area where a large number of dark nebulas, emission gases and eruptive stars give to us this nice show.

I need to explore more in detail this region on my next captures!!!

On this picture I integrate more than 75 hours in narrow band and rgb data to resolve all possible details and structures.

Wikipedia:

La galaxia de Bode (también conocida como Galaxia Espiral M81, Messier 81, M81 o NGC 3031) es una galaxia espiral ubicada a 12 millones de años luz en la constelación de la Osa Mayor. Fue nombrada en honor a Johann Elert Bode, quien la descubrió en 1774. En 1993, una supernova (SN 1993J) fue observada en esta galaxia.

Se presume que la galaxia de Bode contiene aproximadamente 250 000 millones de estrellas, siendo ligeramente más pequeña que la Vía Láctea. La galaxia es uno de los mejores ejemplos del diseño espiral en una galaxia, con brazos casi perfectos dispuestos en espiral hacia su centro. La galaxia de Bode y su satélite (o galaxia binaria), la galaxia del Cigarro, o M82, son de los miembros más prominentes del Grupo M81. Ambas son visibles en el mismo campo de visión para la mayoría de los telescopios.

La galaxia de Bode tiene una magnitud aparente de 6,93, siendo una de las galaxias más brillantes. Bajo condiciones excepcionales y cielos verdaderamente obscuros en lugares remotos, lejos de la contaminación lumínica, puede advertirse a simple vista.

Su centro presenta un característico abultamiento que se ha explicado ya sea como consecuencia del choque con una galaxia vecina que produjo que nubes de gas y polvo interestelar se hayan comprimido, colapsándose para producir masivas estrellas de altas temperaturas, o debido a la existencia de un quásar en su centro, con un agujero negro supermasivo que debilitado produjera un brillo menor a los quásares, pero mayor a lo típico en núcleos de galaxias en espiral. Existe evidencia que apoya esta última versión proporcionada por radiotelescopios que indican que el núcleo se caracteriza por ser pequeño y muy denso, del cual se emiten chorros de gas caliente a gran velocidad posiblemente generados por el campo magnético en torno al agujero negro.

La galaxia del Cigarro (también conocida como Galaxia Irregular M82, Messier 82, M82 o NGC 3034) es una galaxia irregular alargada y estrecha en la constelación de la Osa Mayor. Es el prototipo de galaxia con brote estelar, estando caracterizada por una elevada tasa de formación estelar en su centro, causada según parece por una interacción gravitatoria hace entre doscientos y quinientos millones de años con la primaria galaxia de Bode.

Ese brote estelar duró 50 millones de años, con una tasa de formación estelar de 10 masas solares por año, y fue seguido por otros dos, el último de ellos ocurrido hace entre 4 y 6 millones de años y que parece haber formado los cúmulos del núcleo. Estudios realizados con el telescopio espacial Hubble muestran la presencia de 197 cúmulos estelares allí, con una masa media de 2 - 105 masas solares.

La región dónde se concentra la formación estelar tiene un tamaño de 500 pársecs, y son visibles en ella cuatro regiones brillantes conocidas cómo A, B, C y D, las cuales son interpretadas cómo supercúmulos estelares que sufren relativamente poca extinción debido al polvo interestelar. La frecuencia de supernovas allí es de una cada 10 años. Las producidas en las regiones A y C parecen ser las responsables de los chorros de materia expulsados al espacio intergaláctico visibles en la fotografía.​

El Observatorio de rayos X Chandra detectó emisiones de rayos X fluctuando en la zona, aproximadamente a 600 años luz del centro del objeto. Los astrónomos postularon que podría contener el primer agujero negro de masa mediana conocido, en torno a 500 masas solares. Asimismo, es posible que exista un agujero negro en su centro con 30 millones de veces la masa del Sol.

Estudios llevados a cabo en 2005 por un grupo de astrónomos mexicanos muestran que podría tratarse de una galaxia espiral barrada de tipo tardío y baja masa vista casi de canto, siendo que las distorsiones gravitacionales y las regiones de polvo hacen que presente una morfología irregular.​

Desde entonces, se ha continuado la investigación analizando en detalle el resto de la galaxia, ya no solo su brote estelar central. Llegándose a la conclusión de que una gran parte de las estrellas de su disco nacieron en un gran brote estelar hace 500 millones de años, habiéndose deteniendo la formación estelar allí hace 100 millones de años y dejando cómo prueba de tal brote un gran número de super cúmulos estelares. En la actualidad, el único lugar de la galaxia dónde siguen naciendo estrellas es en su centro y quizás en su halo galáctico, aunque a una escala muy lenta. Todo ello sugiere un escenario según el cual la galaxia del Cigarro era una galaxia de bajo brillo superficial que sufrió el potente brote estelar mencionado que formó gran parte de las estrellas de su disco.

NGC 2359, commonly known as Thor's Helmet Nebula, is an emission nebula located in the constellation Canis Major. This nebula is also sometimes referred to as the "Duck Nebula" due to its appearance resembling a duck in flight. It was discovered by Sir William Herschel in 1785.

The nebula is situated about 15,000 light-years away from Earth and spans about 30 light-years in diameter. It is formed by the fast stellar wind from a massive central star interacting with and shaping the surrounding interstellar medium. The central star, which is a Wolf-Rayet star named WR7, is a massive, hot, and short-lived star that is expected to eventually end its life in a supernova.

Centaurus A or NGC 5128 is a galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta, in New South Wales, Australia. The galaxy is also the fifth-brightest in the sky,making it an ideal amateur astronomy target, although the galaxy is only visible from low northern latitudes and the southern hemisphere.

The center of the galaxy contains a supermassive black hole with a mass equivalent to 55 million solar masses.

The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.

About this image:

Imaged in three key wavelengths of the electromagnetic spectrum of light (Hydrogen-Alpha, Sulfur-II and Oxygen-III), over a few nights (due to poor Astronomical seeing conditions, as a result of a very strong jet stream).

About Emission nebulae:

Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm. The blue light is from doubly ionized Oxygen ions (O2+) emitting at a wavelength of 500.7nm.
