Nebula / Nébuleuse
Carl Sagan, scientifique et auteur, soutenait dans Cosmos que l’homme « s’était attardé assez longtemps sur les rives de l’océan cosmique et qu’il était enfin prêt à partir vers les étoiles.»
Prêts à partir pour les étoiles? Il m’arrive de me demander ce qui arrivera lorsque notre espèce parviendra à rejoindre de lointaines planètes habitables.
Cet exploit sera t-il de nature à changer la culture humaine, la perspective qu’ont les humains sur eux-mêmes et sur les conflits et les peurs qui les animent ici sur ce grain de sable cosmique appelé Terre ou alors…. cette expansion aura t-elle simplement pour effet de transposer à une plus vaste échelle les conflits incessants qui nous opposent ici?
En regardant vers les étoiles, à partir de ma petite planète, je ne veux pas chercher une réponse à ces questions difficiles. L’émerveillement devant la beauté grandiose de cet univers de démesures me suffit. » (Patrice)

Nebula
Carl Sagan, scientist, and author argued in "Cosmos" that man "have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars ».
Ready to go for the stars? I sometimes wonder what will happen when our species manages to reach distant habitable planets. . .
Will this feat be such as to change the human culture, the perspective that humans have on themselves and on the conflicts and fears that animate them here on this cosmic sandstone called Earth or so... will this expansion simply have the effect of transposing at a larger scale the continuing conflicts we have here?
Looking towards the stars, from my little planet, I don't want to seek an answer to these difficult questions. The wonder in front of the grandiose beauty of this universe of excessiveness is enough for me.

Messier 20 (M20, NGC 6514) in Sagittarius is a magnificent deep sky object that combines an open cluster of stars, an emission nebula (red), a reflection nebula (blue) and a dark nebula that divides the emission nebula in three parts, thus giving it the name the Trifid Nebula. The Trifid Nebula lies in a rich area of the Milky Way, with adjacent Messier objects M21 (open star cluster, at upper right) and M8 (Lagoon, a part of which is visible at the left edge) visible in the same binocular field of view. The region is also filled with other emission nebulae such as NGC 6526 (top left) and Sh2-26 (bottom left).
The Hubble and Spitzer Space Telescopes revealed hot, young energetic stars at the central region emitting radiation and stellar jets that tear apart the gas and dust from which stars are born.
M20 is estimated to be about 5200 light years away, at which it spans a diameter of about 10 light years across.
Clear Skies to all!

B33 (Horsehead Nebula) is a dark nebula in the Orion constellation, around 1375 light years from earth.
Because emissions within this region/frame are mostly limited to HA and SII (tiny bit of OIII, but largely neglectable), I decided to see what I could do with only using that data. The reason why there's little OIII emissions in the region is fairly straightforward. Hydrogen (HA) and Sulfur (SII) quite simply have a much lower energy requirement for ionization (the processs that "triggers" these emissions) to take place compared to Oxygen (OIII). Due to there being a lot of dark dust (the whole reason we even see the horsehead) in the area; energy transmission is limited to the extent where there's enough for the former two elements to get ionized, not quite enough for (large amounts of) the latter.
Image acquisition details:
20x1800" HA
30x1800" SII
Used the typical HSS colour scheme and created a synthetic luminance layer on top to pull out a bit more detail. This layer consisted of a combined HA/SII signal, weighted down to include 33% of each.
I've always enjoyed images from space, can't really afford an astro photography rig so I thought I would make my own nebula, three images taken in my kitchen with a small fish tank, water and paint, the 'stars' are air bubbles stuck to the front of the tank, a little play in lightroom then into CS5, layers were blended and a few adjustments, back into lightroom and a little work with curves, contrast and clarity, two flash guns used at 3o/c and 9 o/c and at 12o/c for the last image, not the hubble but I like it😊
The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.It is a rather faint object located about 2 degrees SW of Sadr.

My first record of the Trifid Nebula. The stacked frames, captured on two consecutive nights, totaled 5 hours and 10 minutes of exposure.
"The Trifid Nebula, also known as Messier 20 (M20), is a large star-forming region located in the southern constellation Sagittarius. The nebula’s name means “divided into three lobes,” and refers to the object consisting of three types of nebulae and an open star cluster. The open cluster is surrounded by an emission nebula, a reflection nebula, and a dark nebula within the emission nebula that gives M20 the trifurcated appearance for which it is known".

Serena and i seem to be having an umbrella theme going on, maybe due to the amount of rain in England atm. I might grab an umbrella too and get behind the camera...watch this space!

I wanted to release this a while ago (before the Sinistre eyes), but i changed them a lot, to a point where they barely look like the first editions...
Portion of the Eastern Veil Nebula also known as Caldwell 33, whose brightest area is NGC6992.
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
The Nebula was discovered on 1784 by William Herschel.
Given a distance of 2400 Light Years, this gives the radius of the entire nebula as 64 Light Years.
Undulations in the surface of the shell lead to multiple filamentary images, which appear to be intertwined.

Rework of my latest image from the iris nebula.
Taken over four nights in June and July 2019. Total integration is about 12 hours. 6 h for luminance and 2 h for RGB each.
The Soul Nebula (IC1848) is an emission nebula located in Cassiopeia constellation about 7,500 light years away from earth.
Image taken with my Star71/347mm apo, ATIK383l+ ccd-camera and Baader Ha, SII & OIII filters.
A spectacular emission nebula in the constellation Sagittarius, this is a companion to an equally spectacular nebula called the Trifid Nebula. While the Trifid has a blue reflection nebula visibly close to its emission nebula, the Lagoon emits only in the red spectrum.
Photo was taken through my Stellarvue SV102ED2 using a Canon EOS Ra camera. It is a stack of multiple exposures from 30 s to 5 min, and ranging from ISO 800-12,800. Total integration time is 1 hour. Pre and post-processing was done in Pixinsight.
