With an apparent size and brightness that makes it one of the "biggest" extragalactic object in the night sky, the Great Andromeda Nebula/Galaxy is easily visible to the naked eye (even under relatively poor sky conditions). This image also shows Andromeda's two companion galaxies, M32 (small and to the left of center) and M110 (below and to the right). If you look closely, M110 even shows some faint dust lanes/clouds which is a little unusual for a dwarf elliptical galaxy and a feature that is often lost in many photographs.

This image also reveals an asymmetrical halo around M110 that is most likely the result of a gravitational interaction between M31 and M110 (a tidal stream between the two galaxies).

Photographed on the morning of October 1, 2013 from a moderately dark-sky location using a 5 inch aperture, f/4.2 telescope and a Sony NEX-5N digital camera (ISO3200, a stack of two hundred and three images each exposed for 30 seconds, producing a total exposure integration time of just under one hour and forty-two minutes). Tracking for each of the exposures was performed by a Celestron CGEM mount (no manual or auto guiding, standard sidereal rate after All-Star polar alignment).

Image selection, registration, integration, and adjustments done with PixInsight v01.08.00.1023 RC7 with final tweaks in Photoshop CS5.

The Soul Nebula (IC 1848) in Cassiopeia is situated 6,500 light-years from Earth. This image was captured through a one-hour imaging session (comprising 30 two-minute exposures) utilizing a RASA8 telescope, an ASI2600MC Pro camera, and an IDAS NBZ II dual narrowband filter. The resulting data was processed in Pixinsight and Photoshop.

My northern view is very restricted by trees making this available for just a couple of hours either side of the meridian. I had to wait a good while but I finally managed a decent run at it.

Demetra, ISIS, Pixinsight.

The SII, OIII, and Ha pictures were produced from 84 individual 90 second spectra taken of the planetary nebula M57. Each spectrum was processed with ISIS to generate a complete image at a specific wavelength, in this case for SII, OIII, and Ha, resulting in a color composite image using the Hubble color palette.

I shot this last night between 2:30 am and 4:30 am. It was a gorgeous night, not very many Coyotes either!

This image is a composite of 24 images for the sky (3 rows of 7), and 6 images for the landscape. The sky images were 3-minute exposures each tracked on a Sky-Watcher Star Adventurer tracker. Each raw files was converted to a TIFF file and stitched together into a panorama with Microsoft ICE, and finally processed in Pixinsight and Photoshop.

A closer crop on the widefield LRGB and SHO (SII+Ha+OIII) Narrowband image of the Bubble Nebula (also know as NGC 7635, Sharpless 162, or Caldwell 11). The Bubble Nebula is a H II region emission nebula in the constellation Cassiopeia, and lies close to the open star cluster Messier 52.

The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.

The Helix nebula, commonly known as the Eye of God, or even the Eye of Sauron, looks like a larger and brighter version of M57, the Ring nebula.

This planetary nebula is a very popular target for amateur astrophotographers, not only because it has cool nicknames but it is very easy to capture.

La nebulosa NGC 2736 es una remanente de súper nova, es decir la nebulosa que queda cuando una estrella lo suficientemente masiva explota. En este caso, es la nebulosa que quedó al estallar una estrella hace unos 11.000 años. Es un objeto visible principalmente desde el hemisferio sur, la zona ecuatorial y algunas zonas del hemisferio norte.

Se conoce como nebulosa del lápiz, o también como Rayo de Herschel, en honor a su descubridor, John Herschel, quien la descubrió desde el cabo de Buena Esperanza en Sudáfrica, en 1835. La describió como un rayo extremadamente débil.

Los filamentos trenzados son en realidad largas ondas de gas vistas de costado. Esta nebulosa remanente de súper nova tiene unos 100 años luz de diámetro y su onda de choque surca el espacio a unos 500.000 km por hora.

Description - Taken over 2 nights and processed in PixInsight, M4 which is home to more than 100,000 stars is circa 12-13 billion years old. That's 3 times the age of our solar system and nearly as old as the universe itself! In the top left corner another globular cluster can be seen, NGC 6144. The bright star Antares is just off the frame to the left and reflecting on the dust around the area. An emission nebula, Sharpless 2-9 can be seen clearly to the top right.

Messier 4 or M4 (also known as NGC 6121 or the Spider Globular Cluster) is a globular cluster in the constellation of Scorpius. It was discovered by Philippe Loys de Chéseaux in 1745 and catalogued by Charles Messier in 1764. It was the first globular cluster in which individual stars were resolved.

#Astrophotography

The Pillars of Creation is the most famous image taken by the Hubble telescope. I remember seeing the 1995 original photo on a magazine when I was younger, and it was probably at that time that I began to love astronomy. Back when I started Astrophotography last year, without even having a telescope, M16 was very well positioned in the September night sky, but I couldn't capture it with my little tripod and DSLR.After waiting almost a year for our Earth to complete its turn around our sun again, M16 finally re-appeared.

I hope that one day I can afford a CCD camera to be able to redo this target and capture all the nebulosity of the Eagle.

M 16, the Eagle Nebula with Chile Two telescope of the Slooh network and processing with Pixinsight.The Eagle Nebula (also known as Messier 16 or NGC 6611) is a large H II region in the constellation Serpent's Tail. It is formed by a young open cluster of stars associated with an emission nebula composed of ionized hydrogen, cataloged as IC 4703.

Its distance has always been relatively uncertain, but there is a tendency to accept a value of about 7000 light years from Earth, thus placing it in the middle zone of the Sagittarius Arm; it contains some extremely well-known formations, such as the Pillars of Creation, the long columns of dark gas originating from the action of the stellar wind of the components of the central cluster and which are also responsible for the proper name of the nebula itself, due to their shape. In them there are some young stellar objects, which testify that the processes of star formation are still underway, although it is not clear whether these are favored or opposed by the action of the stellar wind of nearby stars, nor is it clear if the wind actually affects these phenomena in some way. The cluster is composed of a large number of very hot and bright blue supergiants; their typical age is just 2-3 million years, that is, less than one thousandth of the age of our Sun; The brightest star in the cluster is magnitude 8.24, clearly visible even with binoculars.

The nebula has been known since the eighteenth century and is one of the best known objects among those of the Messier Catalog; It reveals itself easily in photographs and is therefore a good subject for fans of amateur astrophotography.

Haven't imaged this for years. Nice to revisit it with slightly newer gear and better image processing techniques.

This galaxy looks very similar to how our own Milky Way galaxy would look from the same distance, which is about 2.5 million light years away. Actually, this galaxy is naked-eye visible from darker skies, and if the human eye could detect it completely, it would appear 5-6 moon-lengths in size! Another interesting tidbit is that this galaxy is on a collision course with the Milky Way, expected to “touch” in about 4.5 billion years from now!

The Great Barred Spiral Galaxy ( NGC 1365 ) in the Constellation Fornax

Below the equator, not seen from much of the Northern hemisphere, NGC 1365 passes very nearly directly overhead an observer situated near Cape Town, as Sir John Herschel was in November of 1837 whne he discovered this “remarkable nebula” that is numbered 2552 in his book of observations from the Cape.

Not called a “nebula” now, of course, this striking object is one of the nearest and most studied examples of a barred spiral ( SB ) galaxy that also has an active galactic nuclei resulting in its designation as a Seyfert galaxy.

At around 60 M light years from Earth, NGC 1365 is still seen to occupy a relatively large area ( 12 by 6 arc minutes ) due to its great size; at some 200,000 light years or so across, NGC 1365 is nearly twice as wide as the Milky Way and considerably wider than both the Sculptor and Andromeda galaxies.

This High Dynamic Range ( HDR ) image is built up from multiple exposures ranging from 4 to 240 seconds with the aim of capturing the faint detail in the spiral arms of the galaxy whilst also retaining colour in the brightest star ( the orange-red 7th magnitude giant, HD 22425 ). Also, scattered throughout the image, and somewhat more difficult to see, are numerous and far more distant galaxies.

The Eagle Nebula is a stellar nursery, a crucible where the primordial ingredients of the universe – interstellar dust and gas – congregate and collapse under gravity's tug to give birth to stars. These newborn stars, energetic and radiant, emerge from their birthplace, shedding light into the cosmic abyss.

The nebula's centre is something both stark and beautiful, pillars of dust and gas illuminated by newborn stars in the shape of an Eagle's claw. We call these monoliths the 'Pillars of Creation.' These titanic structures, light-years in length, are factories of creation, the same processes that gave rise to our own star, our own planet, and ultimately, us. This process has been unfolding for billions of years, long before humans trod the Earth, and will continue long after we're gone. In this, the Eagle Nebula reminds us of our ultimate origin and deep connection with the cosmos.

Here’s my latest image of the Whale and Hockey stick galaxies. This was an attempt to get a few more galaxies before the season ends from a couple of weeks back, and am quite happy with the result given that I got 2 hours of data. You can almost make out the extra tail on the Hockey stick galaxy going to the 5 o’clock position. I hope to revisit this next spring and get a deeper luminance. The luminance I used here was built off the RGB frames.

Brief description:

The Whale (NGC 4631) and Hockey Stick (NGC 4656) galaxies are a pair in the constellation Canes Venatici. The Whale is only 25 million light years away and is a spiral galaxy, nearly seen edge-on and is similar in size to our Milky Way galaxy and even includes a companion elliptical galaxy (NGC 4627). The distorted shape of the hockey stick galaxy suggests these galaxies have had gravitational interactions in the past.

Can you see the wizard?

NGC 7380 is a young open cluster of stars in the northern circumpolar constellation of Cepheus, discovered by Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 9 million light-years from the Sun. The cluster spans ~20 light-years (6 pc) with an elongated shape and an extended tail. Age estimates range from 4 to 11.9 million years.

De SkySafari Plus: la parte más brillante de la nebulosa del Corazón (IC 1805) fue la primera descubierta y se conoce como NGC 896.

Está ubicada en el brazo de Perseo de nuestra galaxia, la Vía Láctea. En el centro se encuentra el cúmulo abierto, Melotte 15, cuya radiación es la responsable del color rojo de la nebulosa. Algunas de las estrellas del cúmulo tienen solo 1.5 millones de años y su masa varía desde fracciones hasta más de 50 veces la masa del sol.

En la imagen además se ven también tres galaxias muy lejanas: PGC2797052, PGC2797053 y PGC138524
