The Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula composed of glowing gases (ionized hydrogen, sulfur and oxygen) and darker cold dust lanes. The nebula is shape and illumination are produced by a central star cluster known as Melotte 15 aka Collinder 26.

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!

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.
The Horsehead Nebula is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion molecular cloud complex
The Rosette Nebula.
Processed in the Hubble Palette, this vast emission nebula is located about 5200 light years from Earth.

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.

The prominent ridge of emission featured in this dramatic skyscape is cataloged as IC 5067. Part of a larger emission nebula with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years following the curve of the cosmic pelican's head and neck. This false color view also translates the pervasive glow of narrow emission lines from atoms in the nebula to a color palette made popular in Hubble Space Telescope images of star forming regions. Fantastic, dark shapes inhabiting the 1/2 degree wide field are clouds of cool gas and dust sculpted by the winds and radiation from hot, massive stars. Close-ups of some of the sculpted clouds show clear signs of newly forming stars. The Pelican Nebula, itself cataloged as IC 5070, is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus.

I present to you an apparently unnamed nebula in the large Sadr nebula complex. In my opinion it is on a par with many better-known nebulae. I especially like those intriguing yellow streaks below the blueish centre of the image. I wonder if they are formed by solar winds and radiation from the stars in the centre.
I took this image from my backyard in Luxembourg (Europe) on the nights between June 18 and 24.
Total exposure is about 17 hours (9h halpha, 4h SII and 4h OIII).
Equipment: 8” ONTC Newton, Avalon Linear mount, ASI 1600mmc Pro and Baader narrowband filters.
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 Dumbbell Nebula, M27 or NGC 6853 is a planetary nebula in the constellation Vulpecula, at a distance of about 1227 light-years. This object was the first planetary nebula to be discovered by Charles Messier in 1764.

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".

Back to adventures in astrophotography. Found in the constellation Gemini, here is a supernova remnant at a distance of 5,000 light years from Earth. The span of the nebula is 70 light years-- must have been quite an explosion! Astronomers can only give a wide estimate of when the supernova event occurred: 8,000 - 30,000 years ago.
I wonder how bright it appeared from Earth...? The brightest supernova in recorded history was observed in 1066 AD. Roughly 16 times brighter than Venus and easily visible during daylight hours, it was written about in many corners of the world. It is said that some North American petroglyphs likely depict the 1066 supernova.
Image obtained after approx 2.5 hours each through Ha and OIII filters. Exposures of 5 minutes. It actually looks like a jellyfish, yes???
WIP.
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...

The Rosette Nebula (also known as NGC 2237 and C 49) is a large, roughly circular H II region located on the edge of a giant molecular nebula in the constellation Unicorn. The nebula has an angular diameter of 1.3° and is located at a distance of 1600 parsecs (about 5200 light years) from the solar system; it is approximately 100 light-years in size. At the center of the Rosette Nebula is a bright open cluster known as NGC 2244; the blue stars of the cluster, forming part of the OB association known as Monoceros OB2, emit ultraviolet radiation, which excites the gas of the nebula leading it to emit red light. The stellar wind from the O and B group of stars is thought to exert pressure on the interstellar cloud causing compression, followed by star formation; in fact, many Bok globules have been observed in the region, believed to be the site of star formation.
