M16 - LBN70 - LBN71 - LBN72
This image transports us to one of the most dynamic regions in our galaxy: the [b]Eagle Nebula (M16 or NGC 6611)[/b]. Located approximately 7,000 light-years from Earth in the constellation Serpens, M16 is a spectacular young star cluster of about 376 stars, embedded within a vast cloud of gas and dust. It's a famous stellar nursery, home to the iconic "Pillars of Creation," where new stars are actively being born. In this wide-field composition, in addition to M16, we can observe the emission and reflection nebulae [b]LBN 70, LBN 71, and LBN 72[/b]. These structures, extending throughout this intricate star-forming region, are also cosmic clouds of gas and dust. LBN 70 is a larger complex that encompasses LBN 71 and LBN 72, adding richness and depth to this fascinating cosmic landscape. This particular capture was made using a variety of filters, including the [b]Askar Colourmagic Ultra E1 and E2[/b], the [b]Altair Ultra 4nm Ha-OIII and SII-OIII[/b], and the [b]Optolong L-Ultimate[/b]. This diverse filter set was used as part of a comparative test for an upcoming video on my YouTube channel, [b]Astrotivissa[/b], where I'll be exploring the performance differences of these filters. The image, processed with an [b]SHO (Sulfur II, Hydrogen-alpha, Oxygen III)[/b] palette, reveals the distribution and composition of ionized gases, highlighting the complex interactions and varying temperatures within these cosmic structures.

Barnard's Loop & M78
The M78 region, located in the constellation of Orion, constitutes an area of great astrophysical interest due to its rich diversity of objects and stellar processes.M78, classified as a reflection nebula, is visible thanks to the starlight scattered by cosmic dust. This nebula harbors young stars of spectral type B, whose ultraviolet radiation ionizes the surrounding gas, causing it to glow.In the vicinity of M78 extends the Barnard's Loop, a vast structure of ionized hydrogen that forms part of the Orion Molecular Cloud Complex. This arc, with an apparent size of several degrees in the sky, is believed to be the remnant of one or more supernova explosions that occurred in the past.The interaction between massive stars, the ionized gas of Barnard's Loop, and the dense molecular clouds in the region generates a complex dynamic. Stellar winds and radiation from young stars erode and compress molecular clouds, triggering the formation of new generations of stars.The study of the M78 region and Barnard's Loop allows astronomers to better understand the processes of star formation, the evolution of the interstellar medium, and the influence of massive stars on their environment. Ground and space observatories, using different wavelengths, continue to reveal new details about this fascinating region of the sky.

The Soul Nebula (IC 1848): A Stellar Melting Pot
The Soul Nebula, also known as IC 1848 or Sh2-199, is a vast star-forming region located about 6,500 light-years away in the constellation Cassiopeia.This emission nebula, composed mainly of ionized hydrogen, glows with an intense red light. Inside, young, massive stars emit ultraviolet radiation that excites the surrounding gas, creating a spectacle of ethereal shapes and vibrant colors.The Soul Nebula is home to several open star clusters, including CR 34, 632, and 634. These clusters, formed by young stars born together from the same molecular cloud, are witnesses to the dynamic process of star formation in the region.Observing the Soul Nebula is like contemplating a "star factory" in full activity, where clouds of gas and dust collapse under their own gravity to give rise to new generations of stars. [b]Some interesting facts:[/b] [list] [*][b]Size:[/b] It spans approximately 100 light-years. [*][b]Cosmic neighbor:[/b] It is located near the Heart Nebula (IC 1805), with which it is sometimes photographed together.

Flaming Star Nebula & Tadpoles Nebula
The constellation Auriga hosts a fascinating array of deep-sky objects, and among the most notable are the Flaming Star Nebula (IC 405) and the Tadpoles Nebula (IC 410). Both nebulae, though visually distinct, share a common origin in star formation and offer astronomers and astrophotographers a breathtaking spectacle.[b]The Flaming Star Nebula (IC 405)[/b]This emission and reflection nebula owes its name to its appearance, which evokes a cosmic flame. Its characteristic red color is produced by the ionization of hydrogen present in the nebula, caused by ultraviolet radiation from the star AE Aurigae, a massive star of spectral type O located within it. In addition to red, the nebula exhibits bluish regions, a product of the reflection of starlight by cosmic dust.IC 405 is located at a distance of approximately 1,500 light-years from Earth and spans about 5 light-years in diameter. Its filamentary and chaotic structure is the result of the interaction between stellar radiation, stellar wind, and the clouds of gas and dust that compose it.[b]The Tadpoles Nebula (IC 410)[/b]About 12,000 light-years away, the Tadpoles Nebula is an emission nebula surrounding the open star cluster NGC 1893. Its name comes from the distinctive "tadpole" shapes observed within it. These structures are gaseous globules, dense clouds of gas and dust where new stars are forming.Ultraviolet radiation from the young stars of the NGC 1893 cluster ionizes the gas in the nebula, causing it to glow in a predominantly reddish hue. The "tadpoles" are denser and resist erosion by the stellar wind, creating these elongated shapes that appear to swim through the nebula.

Bubble Nebula - NGC 7635
The Bubble Nebula (NGC 7635) is a stunning cloud of gas and dust located about 7,100 light-years from Earth in the constellation Cassiopeia. Its name comes from its distinctive spherical shape, caused by powerful stellar winds generated by a massive star at its center. This star, about 45 times larger than the Sun, expels material that sculpts the surrounding gas, creating the appearance of a bubble. The interaction between stellar radiation and the surrounding gas creates a fascinating blend of colors and textures, making it an impressive target for astrophotography. This astrophotography project was captured by [b]Carlos Espada[/b] (@carlosespadaapo) from his observatory. Despite living with ALS and only being able to move his eyes, Carlos has adapted his capturing techniques and equipment to continue pursuing astrophotography. I have taken care of the image processing, a task that presents challenges for him given his condition.

IC410 - Tadpoles Nebula
IC 410 is located about 12,000 light years away, and is more than 100 light years in diameter. It has been sculpted by stellar winds and radiation from the open cluster NGC 1893. Formed embedded in the interstellar cloud just 4 million years ago, radiation from these hot stars pushes gas out of them and creates dark "tadpoles." These streamers of denser gas resist erosive radiation from hot stars. The tails have grown to 10 light years in length, and are potentially sites of ongoing star formation. This is the third collaboration with Carlos Espada (@carlosespadaapo), who has suffered from ALS for years and can only move his eyes. With them he controls and manages his astrophotography equipment, and I have the honor once again of putting my hands at his disposal to carry out the processing. Las fotografías las tomó durante 6 noches especialmente turbulentas, con mala visión y mucha corriente en chorro, lo que me obligó a acumular hasta 20 horas de exposición, repartidas de la siguiente manera: 6 horas UVIRcut, 7 horas Optolong L-enhance y 7 horas Askar. D2 (SII OIII). Todas las luces 300.

M33 - Triangulum Galaxy
The Triangulum Galaxy or spiral galaxy M33, this nearby spiral is the third largest galaxy in the Local Group, after the nearby Andromeda Galaxy (M 31) and our own Milky Way. Despite its modest size, M 33 is home to one of the largest known H II regions, NGC 604, which has a diameter of about 1,500 light years. M33 contains between 30,000 and 40,000 million stars and is located 2.8 million light years from us. This project is the second that I carry out together with Carlos Espada (@carlosespadaapo), who with only his eyes due to the terminal disease called ALS monitors and programs the captures of his observatory, and I carry out the image processing. It is once again an honor for me to be able to collaborate with him and to be able to treat his data with the greatest care possible. 144 shots of 5 minutes of exposure, 1/3 with each filter: UVIRCUT, IDAS D1 when there was a moon, and L-enhance to remove the nebulae. Integrating 12 hours of exposure time.

Pacman nebula, NGC 281 (Pacman nebula, NGC 281)
NGC281 or the Pacman Nebula is a region of HII located in the Cassiopeia constellation and about 9,500 light years from us. This photo and the shots that make up its integration have been taken only with the eyes, the eyes of Carlos Espada (@carlosespadaapo) who has suffered from ALS for years, reaching the point of only being able to move that part of his body. Despite this, Carlos set out to be the first astrophotographer with ALS and in 2017 he bought a telescope and began studying. Today he manages NINA and the capture programs with his eyes. Without a doubt a case of exceptional improvement that we should all learn from. For this project it has been my honor to be able to help you process the image of this nebula using your data. All my recognition, congratulations and gratitude. Thank you very much Carlos for this honor you have granted me. 🙏
