"The Elephant’s Trunk Nebula is a dense region of dust and gas found within the considerably larger star forming region IC 1396 in Cepheus constellation. Designated IC 1396A, the elongated globule of dust and gas was named the Elephant’s Trunk because it resembles an elephant’s head and trunk at visible wavelengths, appearing as a dark patch with a bright winding rim. It is located at a distance of 2,400 light years from Earth."
i captured this image with my William Optics FLT132, FLAT8 0.72x reducer, ZWO ASI2600MC Pro camera and ZWO AM5 mount. I used the Antlia Triband RGB Ultra for around 2 hours and then the Optolong L-Ultimate narrowband filter for another 6 hours, with a total 8 hours integration time over two consecutive nights (in 180 and 300 second subs).
Pre and post processed in PixInsight, with final touches in Affinity Photo 2. i used the GeneralizedHyperbolicStretch (ghsastro.co.uk) in PixInsight, which was super useful in extracting/showing the dust clouds in this image. This is the SHO palette with RGB stars.

NGC 6914 (the blue/green light in the centre of the image) lies 6,000 light-years away in Cygnus and is a very rare region in which one can see all three classes of nebulae, red emission, blue reflection, and dark obscuring, within a very small expanse of sky. The broad expanse of hydrogen gas is re-emitting red hydrogen alpha light as a result of ionization from the ultraviolet light from several hot stars of the Cygnus OB2 association. These stars also illuminate the blue reflection nebulae of residual dust from their formation. The entire tableau silhouettes numerous dark nebulae also being sculpted by the stellar winds emitted by these stars.

A few days back I once again managed to grab some time under the stars - I was hoping for an all night data capture but the ever present clouds rolled in, limiting my data capture to a couple of hours and 20 x 5 minute exposures only. That said, this didn't come out too bad but I will improve upon it with another clear night. This is the Bogeyman Nebula, so called because of the silhouette of an intriguing dark figure in the centre of the image, Lynds' Dark Nebula (LDN) 1622, appearing against a faint background of glowing hydrogen gas. LDN 1622 lies near the plane of our Milky Way galaxy, close on the sky to Barnard's Loop (a small part of which is on the right of this shot) - a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of the Orion constellation. The Bogeyman is much closer to Earth than the Orion Nebula though, lying a mere 500 light years away, or put another way, 2939500000000000 miles. Travelling at 1000 miles an hour it would take 335 million years to get there...!

The Pleiades star cluster is hands down my favorite object in the nighttime sky. Known by many names and by every civilization to ever inhabit our planet, Messier 45 ("The Seven Sisters", "Subaru", "The Hen with her Chicks"), is easily visible to the unaided eye, even from moderately light-polluted skies. Each of the bright stars is named for mythological characters Atlas, Pleione, and their 7 daughters, Alcyone, Merope, Sterope, Maia, Taygeta, Celaeno, and Electra. Not only do these characters feature prominently in Greek mythology, the star cluster itself does as well: In Homer's Odyssey, Odysseus uses the cluster as a navigational beacon. The cluster is mentioned 3 times in the Bible and is illustrated in a prehistoric cave painting at Lascaux. It's also the corporate logo for carmaker Subaru.
It contains at least 1,000 stars, but only 5 to 10 are bright enough to be seen with the unaided eye, and these are the ones that people are referring to when they say "The Pleiades". Each of these giant stars is far brighter than our Sun. If you were to observe the Sun from the same distance, you would need binoculars or a telescope to see it at all!
It is estimated to be 444 light-years away and it's diameter is 15 light-years. The stars are surrounded by interstellar dust and gas. This material would ordinarily be invisible to us, but it’s illuminated by the stars in what’s known as a reflection nebula. The nebula is blue, caused by a light scattering effect not unlike the one that colors Earth’s sky blue. Its wavy appearance comes from interactions between the nebula and the stars’ magnetic fields.
The myth of the Pleiades cluster and the constellation Orion is that the Hunter is enamored with the beauty of the young maidens and he is greedily pursuing them across the sky each night. Indeed that is the easiest way to spot the Pleiades. Find Orion and scan over in the direction he's facing and you'll find them within Taurus the Bull.

Messier 27 (M27) as known as the Apple Core Nebula, is a planetary nebula in Vulpecula. M27 is approximately 1,360 light years away. Discovered by Charles Messier in 1764 who added it to his now famous catalog used by amateur astronomers around the world. A planetary nebula has nothing to do with planets but is created when a star blows off its outer layers after it has run out of fuel to burn. Our own sun will suffer this fate without some external intervention in some 5 billion years.

Sh2-114 Il Drago Volante
Sh2-114 è una debole nebulosa a emissione visibile nella costellazione del Cigno. La sua forma ricorda proprio un dragone volante, per questo le è stato assegnato il soprannome di Flying Dragon Nebula. Si individua nella parte nordorientale della costellazione a circa 2° in direzione nordovest rispetto alla stella τ Cygni. Il periodo più indicato per la sua osservazione nel cielo serale ricade fra i mesi di luglio e dicembre ed è notevolmente facilitata per gli osservatori posti nelle regioni dell’emisfero boreale terrestre. Sh2-114 è una nube ben poco studiata al di là della sua mera catalogazione, dall’aspetto filamentoso e costituita apparentemente da più filamenti arcuati sovrapposti; possiede una forma a semicerchio con la concavità orientata verso sud e pare costituire, assieme alla vicina nube Sh2-113, una struttura a bolla simile a un resto di supernova. Tuttavia, nessun resto di supernova è mai stato descritto in questa regione. Dati acquisiti il 13,14 e 15 Giugno 2024 con filtri Optolong Astronomy Filter RGB e Explore Scientific HA 7nm.

The Rosette Nebula (also known as Caldwell 49) is a large spherical H II region (circular in appearance) 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, the stars of the cluster having been formed from the nebula's matter.
The cluster and nebula lie at a distance of some 5,000 light-years from Earth) and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
A survey of the nebula with the Chandra X-ray Observatory has revealed the presence of numerous new-born stars inside optical Rosette Nebula and studded within a dense molecular cloud. Altogether, approximately 2500 young stars lie in this star-forming complex, including the massive O-type stars HD 46223 and HD 46150, which are primarily responsible for blowing the ionized bubble.

Situada no rico campo estrelado de Sagitário, esta nebulosa com uma extensão aproximada de 5000 anos-luz [3], juntamente com M8 (Nebulosa da Laboa) e M20 (Nebulosa Trífida) formam o famoso tripleto de Sagitário. Neste campo é possível encontrar nebulosas escuras do catálogo de Barnard, nebulosas de emissão, nebulosas de reflexão e também uma nebulosa planetária. Grande parte da imagem é tomada por nebulosa de emissão composta em sua grande maioria por hidrogênio, o elemento químico mais abundante do universo. O hidrogênio, quando encontra-se na forma ionizada, emite luz vermelha.
O lóbulo vermelho à direita da imagem é uma nebulosa de emissão e reflexão catalogada por IC1274, onde é possível visualizar estrelas extremamente energéticas da classe espectral B. As nebulosas de reflexão neste lado da imagem que se apresentam na cor azul não estão evidenciadas nesta imagem devido à técnica de utilização no canal de luminância do filtro Ha.
No lado esquerdo da imagem é possível observar outra nebulosa de emissão bem brilhante com uma tênue nebulosa de reflexão acima, esta nebulosa de emissão é catalogada como NGC6559. A partir de NGC6559 é possível notar uma nebulosa escura, composta por uma densa poeira opaca, que serpenteia em direção ao centro da imagem. Essa nebulosa escura é catalogada como Barnard 303.
No lado centro-esquerdo observa-se um pequeno objeto vermelho brilhante. Trata-se de uma nebulosa planetária do tipo 1 catalogada como GN 18.06.6.01 ou PN M 1-41 [1]. Nebulosa planetária, que não tem nenhuma correlação física com planetas, é um dos estágios finais da vida de uma estrela quando ela ejeta suas camadas para o espaço. Nebulosas planetárias de Tipo 1 são nebulosas que ejetam o material estelar a partir dos polos devido à rotação da estrela [2].

Located in the rich starry field of Sagittarius, this nebula with an approximate extension of 5000 light years [3], together with M8 (Laboa Nebula) and M20 (Trifid Nebula) form the famous Sagittarius triplet. In this field it is possible to find dark nebulae, emission nebulae, reflection nebulae and also a planetary nebula. Most of this image is taken by an emission nebula composed mostly of hydrogen, the most abundant element in the universe. When hydrogen is in ionized form, it emits red light.
The red lobe to the right of the image is an emission and reflection nebula cataloged by IC1274, where it is possible to view extremely energetic stars of spectral class B. The reflection nebulae on this side of the image that appear in blue are not shown in this image due to the technique of use in the luminance channel of the filter Ha.
On the left side of the image it is possible to see another very bright emission nebula with a faint reflection nebula above, this emission nebula is classified as NGC6559. From NGC6559 it is possible to notice a dark nebula, composed of dense opaque dust, which snakes towards the center of the image. This dark nebula is classified as Barnard 303.
On the center-left side there is a small bright red object. It is a type 1 planetary nebula classified as GN 18.06.6.01 or PN M 1-41 [1]. Planetary nebula, which has no physical correlation with planets, is one of the final stages of a star's life when it ejects its layers into space. Type 1 planetary nebulae are nebulae that eject stellar material from the poles due to the rotation of the star [2].

Nome: NGC 6188
Tipo: Aglomerado estelar aberto com nebulosidade
Distância: 4.000 anos-luz
Constelação: Ara [1]
NGC 6188 é uma nebulosa de emissão localizada a cerca de 4 mil anos-luz de distância na constelação Ara (do Latin: "O Altar"). Tem um raio de cerca de 300 anos-luz. O brilhante cluster aberto NGC 6193, no topo da imagem, visível a olho nu, é responsável pela nebulosa de reflexão dentro de NGC 6188.[1] A nebulosa é nomeada por muitos astrofotógrafos como Dragões de Ara por causa da forma de sua nebulosidade no centro.
NGC 6188 é uma nebulosa formadora de estrelas, e é esculpida pelas estrelas maciças e jovens que se formaram recentemente - algumas têm apenas alguns milhões de anos de idade. O início desta formação provavelmente foi causada quando um último lote de estrelas tornou-se supernovas.[1]
NGC 6193 é cluster aberto contendo 27 estrelas, visível a olho nu.[1] NGC 6193 situa-se no centro da associação Ara OB1, que se estende por um grau quadrado. O cluster é associado (e fornece a radiação energizante para) com as regiões vizinhas da nebulosidade de NGC 6188.[1]
A estrela mais brilhante na imagem é de fato um sistema de estrelas múltiplas dominado por dois sistemas de classe O.[1] A estrela HD 150136 é um sistema triplo[2] enquanto que a estrela HD 150135 é um sistema binário[3]. HD 150136 tem uma magnitude aparente de 5.54 e HD 150135 tem 6.89.[1]

Name: NGC 6188
Type: Open cluster with nebulosity
Distance: 4,000 light-years
Constellation: Ara [1]
NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara (Latin: "The Altar"). It has a radius about 300 light-years. The bright open cluster NGC 6193, at the top of image, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188.[1] The nebula is nominated by many astrophotographers as Ara's Dragons because of the shape of the nebulosity at the center.
NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova.[1]
NGC 6193 is open cluster containing 27 stars, visible to the unaided eye.[1] NGC 6193 lies at the center of the Ara OB1 association, which extends over a square degree. The cluster is associated with (and provides the energizing radiation for) neighboring regions of the nebulosity NGC 6188.[1]
The brighter star in the image is indeed a multiple star system dominated by two O class system.[1] The star HD 150136 is a triple system[2] while HD 150135 star is a binary system[3]. HD 150136 has an apparent magnitude of 5.54 and HD 150135 has 6.89.[1]

Gamma Cygni Nebula is at 3700 Light Years away, and Crescent Nebula is at 4100 Light Years away, which looked shining gas around it widely with bluish green OIII, doubly ionized oxygen light from behind Gamma Cygni Nebula.
The light, I feel, revealed three dimensional vast structure of Gama Cygni Nebula area. The area has vast shell or bubble structure. The shell is illuminated from inside, and the shell itself is shining red. Inner surface is bluish green plus red, and outer surface is red alone and darker. The shell is dense toward 10 o'clock direction and thin toward 4 o'clodk direction and toward us.

NGC 5985, NGC 5982 and NGC 5981 are three galaxies in the constellation Draco, collectively known as Draco Triplet. This triplet is less known than Leo Triplet and unlike it, most probably these three galaxies are not interacting with each other.
These galaxies are part of a larger group of galaxies known as the NGC 5982 Cluster.
The integration time is not as much as I think it would be needed given the Bortle 8 location it was taken from and, as a result, I was only able to process it reasonably after several attempts.
