The Statue of Liberty or maybe a furious Jeanne d'Arc. Named NGC 3576 and it is a bright emission nebula in the Sagittarius arm of the galaxy about 9000 lightyears from the Earth.

When the weather is not playing along, it is fun to fiddle with old data and experiment with different processing techniques.

Here is a starless version of Pickering's Triangle (NGC 6979), also called Pickering's Triangular Wisp in the Veil Nebula (a filamentary Supernova Remnant).

The Veil nebula was born out of the death explosion of a massive star, and the expanding shockwave is situated 1,500 light-years away.

Re-processsing of earlier data. Taken with iTelescope T14 (Takahashi FSQ 106, SBIG STL-11000M CCD, Paramount GT-1100S mount and Astrodon narrow band filters). 6 by 5 minute exposures were taken with Ha, SII and OIII. Processing was done with PixInsight, Adobe Lightroom and Adobe Photoshop. Instead of using the Hubble color palette, Ha was mapped to red, SII mapped to green and OIII mapped to blue.

Neptune was very difficult to capture. It is so small and dim. Don't get me talking about the focus! Not sure I had it right really. Spent some time cleaning up the large amounts of noise caused by having the gain up to much to get anything at all.

At least it's one for the collection.

The Running Man Nebula or NGC 1977 is a reflection nebula that is found in the Orion constellation ... almost 1500 lightyears away. It is called the Running Man because the shape looks exactly like that ... ie a man running. It is to the left in this photo ... a purple shape on a field of blue. But in the night sky the Running Man is actually above Orion, but here in this photo I rotated it so that you could see it better.

The Orion Nebula (Messier 42 or NGC 1976) on the right here in this photo is a diffuse nebula just south of Orion's Belt in the constellation of Orion. It is a bright nebulae and is visible to the naked eye in the night sky ... but only as a faint fuzzy smudge unless you have the help of a telescope.

This image is composed of only 11 images stacked and processed in PixInsight and Photoshop. With more images there would be much more detail visible.

The Elephant's Trunk Nebula is an emission nebula associated with IC 1396, a star cluster in the constellation Cepheus. This 6-panel mosaic spans approximately 4 degrees , about 8x the apparent width of the Moon. Image data was captured under dark skies near Goldendale, WA.

The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula is estimated to be between 4,000–6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulae, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006, four Herbig–Haro objects were detected within the Hourglass, providing direct evidence of active star formation by accretion within it.

Object description at www.billionsandbillions.com

Sh2-112 is a visibly emitting nebula in the constellation of Cygnus.

It is located in the northern part of the constellation, about 1.5 ° to WNW of the brilliant star Deneb.

It is a circular H II region of apparent size of about 15', crossed by a dark band on its western side oriented in a north-south direction. It is believed that the star responsible for its excitation is BD+45 3216; estimates of the distance of this star provide a value of 1740 parsec (about 5670 light years), which would place so Sh2-112 in a region of the Orion Arm particularly rich and physically very close to the great nebulous system of Cygnus X.

CTB-1 aka The Garlic Nebula

IG: www.instagram.com/p/CTp1xyVhXIN/

AB: www.astrobin.com/nbsqqv/B/

This image was captured from my backyard observatory (total integration time: 25 hours)

CTB 1 is a supernova remnant (SNR) in the constellation Cassiopeia. This particular SNR was catalogued by George Abell as a planetary nebula in his now well-known catalogue as Abel 85 but it was suggested by van den Bergh in 1960 and confirmed by Willis & Dickel in 1971 to be, in fact, not a planetary nebula but rather a galactic SNR. CTB 1 is approximately 9784 light years away and physically spans another 98 light years in diameter while it is dated to be approximately 10,000 years old.

A recent study by Schinzel et al. reports that a pulsar was running away from CTB-1. The pulsar was likely born from the very same supernova explosion that produced the remnant. Supernova explosions don’t have a perfect symmetry, and the pulsar likely received a natal kick that sent it tearing away from its birthplace at speeds exceeding 1000 km/s, causing it to eventually overtake the expanding shell of gas and dust.

(link to the study: iopscience.iop.org/article/10.3847/2041-8213/ab18f7)

The area top left of CTB1 has been confirmed as a shell rupture. This is likely to be the result of the supernova remnant's interaction with a nearby cavity of neutral hydrogen gas.

Also see the previous version, which was proceeded to more clearly highlight the elements of Hydrogen and Sulfur at the red end of the Spectrum, and the doubly ionized Oxygen at the blue end of the Electromagnetic Spectrum of Light. Rosette Nebula in Narrowband.

About this image:

A Hydrogen-Alpha + Sulfur-II + Oxygen-III Narrowband image of the Rosette Nebula (also known as NGC 2237 or Caldwell 49).

The Rosette Nebula is a large, spherical H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, as the stars formed from the nebula's matter.

The cluster and nebula are at a distance of 5,000 light-years from Earth and measure roughly 50 light-years in diameter. The radiation from the young stars excite the atoms in the nebula, causing it to emit radiation (producing the emission of the nebula at specific spectral lines that we can image).

A HaOIII narrowband image of the Eagle Nebula (catalogued as Messier 16, M16, or NGC 6611).

The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7,000 light-years from Earth.

A spire of gas that can be seen coming off the nebula in the north-eastern part is approximately 9.5 light-years or about 90 trillion kilometers long. The nebula contains several active star-forming gas and dust regions, including the "Pillars of Creation".

About this image:

This image consists of old narrowband Hα and OIII data, that I reprocessed after combining it with more data that I recently imaged.

The Hydrogen dust and gas (the most basic and abundant element in the Universe), emits in the Red part of the spectrum, and the doubly ionized Oxygen emits in the Blue part of the spectrum.

Wavelengths of light in this image:

As I enter my 4th year of being an astrophotographer, I can finally tick this target off my list.

Barnard's Loop is a Hydrogen Alpha (the red stuff) rich emission nebula in the constellation of Orion. It's difficult to capture since it's a faint nebula. I've imaged it before but wasn't satisfied with the result.

And so, it became the 1st target of #EveryNewMoon, an imaging project Cory and I started for 2016.

I'll write more about the project in the next few weeks.

It was very difficult to work with such a rich star field. Shooting at 24mm meant millions of little pin-point stars. 2 Iterations of star reduction, and I'm scared that now the sky appears noisy. But in fact, it's just the ridiculous amount of stars in the image!

Nebulosa da Lagoa

Messier 8

Na constelação de Sagitário, se encontra um dos mais belos objetos do céu noturno. Essa gigante nuvem interestelar foi descoberta por Giovanni Battista Hodierna aproximadamente no ano de 1654. Situada a aproximadamente 5200 anos-luz da terra, a vista desta nebulosa através de um binóculo, apresenta apenas uma mancha clara e oval, destacando-se apenas o aglomerado aberto, sobreposto a nebulosidade.

Embora pareça cinza ao olho humano, em fotografias de grande exposição, a característica cor Rosácea, nos apresenta esse majestoso objeto. A região mais Brilhante da nebulosa foi descoberta por John Herschel, e ficou conhecida como a Nebulosa da Ampulheta, região com intensa formação estelar. Grande parte do brilho da nebulosa é devido a estrela 9Sagittarii, que fica próxima a região brilhante. É classificada como uma nebulosa de emissão, onde os gases ionizados, em especial o hidrogênio, emite radiação principalmente no comprimento de onda na faixa da luz visível vermelha.

Introducing the Hercules Globular Cluster aka the Great Globular Cluster in Hercules (Messier 13 or NGC 6205). I haven’t stopped marveling at the thought of so many stars packed into so relatively dense a structure as this. Or even that something like this is possible.

This bright gob o’ light is a globular cluster comprised of several hundred thousand stars in the constellation of Hercules. A globular cluster is a tightly packed group of old stars which are packed closely in a symmetrical form. Globular clusters formed from giant molecular clouds, or huge masses of gas which form from stars as they collapse. Globular clusters are older structures relative to the universe as less free gas is available today for formation of globular clusters than was the case when the universe was denser.

In 1716, English astronomer Edmond Halley noted of the Hercules Globular Cluster, “This is but a little Patch, but it shews itself to the naked Eye, when the Sky is serene and the Moon absent.” To the human eye, under sufficiently dark skies with binoculars, the Hercules Globular Cluster looks like a dim and somewhat hazy star. The Hercules cluster is one of the brightest globular clusters visible in the northern hemisphere and is about 145 light years in diameter (our Milky Way is over 100,000 light years) by way of comparison and is 22,180 light years from earth.

Technical Details:

This photograph was created using a large quantity of individual exposures captured with a telescope, astronomy camera, and an equatorial mount. Processing was done in PixInsight and Adobe Photoshop.

I didn’t capture these exposures with any particular plan in mind. I just had so much data on this target that I went back and used a lot of my best data to create this final image. It would have been sensible to produce this image with one telescope (e.g. the 120 ED) and camera (e.g. 2600MC or 2600MM combining sessions of luminance and RGB). A bright globular cluster also does not require so much integration time.

Separate sessions calibrated with darks, flats (typically sky flats), and dark flats. Sessions were stacked, background light gradients extracted, calibrated, and then combined into a few monochrome masters (combined selectively for the best result) and a series of color images used for color.
