Detection of an OIII arc in Gemini

An arc-shaped emission nebula in the constellation Gemini with dominant OIII lines and an apparent length of about 14° is presented. The object has already been recorded in far UV surveys. What is new, however, is that this object can be seen in visible light and that it is an OIII emitter.

*** 6h Journey to Rho Ophiuchi ***

Rho Ophiuchi is one of the most colorful regions in the night sky, located near the constellation Ophiuchus. This celestial wonder showcases a stunning array of dark clouds, bright reflection nebulae, and vivid emission nebulae. Additionally, this image prominently features the bright star Antares, the globular clusters M4 and NGC 6144, and the star Alniyat, adding to the rich tapestry of this celestial scene.

What’s in the Image?

Dark Clouds:
The dark patches are molecular clouds, dense regions of gas and dust where new stars are born. They block the light from the stars behind them, creating a beautiful contrast against the brighter regions.

Bright Reflection Nebulae:
The blue areas are reflection nebulae. They glow because the light from nearby stars reflects off the dust particles in the cloud. These stars aren’t hot enough to ionize the gas, but their light scatters, creating a beautiful blue hue.

Emission Nebulae:
The reddish areas are emission nebulae. The gas here is energized by nearby hot stars, causing it to glow. This glow comes from hydrogen gas, the most common element in these regions.

Notable Stars and Clusters:

• Antares: This bright star is prominently depicted in the image. It is one of the brightest stars in the night sky and part of the Scorpius constellation.
• Alniyat: Another bright star that adds to the visual spectacle.
• Globular Clusters M4 and NGC 6144: These clusters appear as dense collections of stars, adding to the intricate details of the region.

Equipment Used:

• Telescope: William Optics RedCat 51 II
• Camera: ZWO ASI2600MM Pro
• Mount: Skywatcher NEQ-6 Pro

Site: Skull Valley, Utah
Telescope: Celestron EdgeHD 8 (0.7x Reducer)
Camera: ZWO ASI2600MM Duo
Mount: Rainbow Astro RST-135E
Exposures: 80x900s Hα, 74x600s OIII, 108x120s Broadband
Software: PixInsight & Adobe Photoshop

This image of the Dumbbell Nebula is HOO with a little broadband data blended for less duo-tone color ranges and some faint background detail around the planetary nebula, along with RGB stars. I imagined it across multiple sessions in 2022 and 2023, but only recently reached a result where I am happy with the stars. The region felt too “naked” if they were reduced too much. My goal was to bring out a lot of lovely, faint detail in the “wings” of M27, and I’m pretty happy with what I accomplished there!

The neighborhood of IC1311

Click to view full size image

Located in the heart of the Cygnus constellation, this field is rich in structures and objects.
One can observe bright nebulae like LBN223, several dark nebulae like B434, the open cluster IC1311, and even the small planetary nebula Patchick6.
The strong presence of Ha and Oiii signals gives this field a rather unusual magenta hue.

Ultra deep M81-M82. Potential new discovery of stellar tidal tail in M82

This photo was taken over a period of 6 months, from January to June of this year, and has 231 hours of total exposure. Taken in Spain.
A new faint stellar tidal stream can be seen to the left of M82.
In addition, the faint IFN can be seen in great definition throughout the photo. Thousands of galaxies can also be seen in the background due to the good sky from which it was photographed and the long exposure time it has.

Location: Uluru, Australia

This image was a difficult one to get, as the national park around Uluru closes at night. Luckily there was a five minute window where it was dark enough to shoot the sky before we had to leave, and the center of the Milky Way was perfectly positioned above the famous landmark.

The Clamshell Nebula, SH2-119.

This is a large but diffuse nebula located in Cygnus, just a few degrees from the brighter North America Nebula. This target is large but dim and needs a lot of integration time using narrowband, as compared to its brighter neighbors. The sulphur and Oxygen especially is pretty dim. I spent 25 hrs on this target.

Located about 2,200 light-years away, this emission nebula spans roughly 70 light-years across. Its glow comes from ionized hydrogen, energized by the hot, young stars within it, including the massive star 68 Cygni. Sh2-119 is a rich field for studying star formation and the complex dynamics of interstellar gas.

The Running Chicken Nebula

The Running Chicken Nebula by Alessandro Carrozzi, su Flickr

IC 2944 is an emission nebula about 6,000 light years away, commonly called the Running Chicken Nebula, a rather creative name (I still don't understand how one can see a figure of a chicken in it...). It is also famous because it is very rich in Bok globules, small clouds of gas and dust so dense that they block out visible light. The image was taken in narrow band, i.e. with filters that select the emissions of the main elements that constitute the nebula, in this case sulphur, hydrogen and oxygen, and putting together data from 2 telescopes placed about 8000 km apart in Chile and Namibia for a total of almost 7 h of exposure!
Technical data. System 1 (Chile): Takahashi Epsilon 180 mm (500 mm focal length) with ZWO ASI 2600 MM. 10x300s SII (5 nm), 32x120s Ha (5 nm), 10x300s OIII (5 nm).
System 2 (Namibia): Takahashi FSQ 106ED (530 mm focal length) with Moravian C3-61000. 17x300s SII (8 nm), 17x300s Ha (7 nm), 17x300s OIII (8.5 nm)

NGC 6914 - The Beating Heart Of Cygnus (HaLRGB) by Ali Alobaidly, on Flickr

NGC 6914 - The Beating Heart Of Cygnus (HaLRGB)

Description:

The beating heart of Cygnus, NGC 6914, is a cosmic canvas where the universe seems to have splashed its palette with reckless abandon. It is a place where stellar nurseries hum lullabies to newly born stars, and where clouds of gas and dust perform an intricate ballet, shimmering in hues of electric blue and fiery red. Here, photons from young, unruly stars race through space, igniting hydrogen gas in a radiant light show that would put any fireworks display to shame. The dark nebulae surrounding the colorful heart complete the convergence of reflective, emissive, and dark regions. Roughly 6,000 light-years away from Earth, it lights up Cygnus with massive young stars emitting intense ultraviolet radiation, causing the surrounding hydrogen gas to glow vividly, while nearby dust clouds reflect the starlight, producing a blue hue. The region is also part of the larger Cygnus X star-forming complex, one of the most active stellar nurseries in our galaxy.

M8 - Nestled in a bed of Gold (4 Panel Mosaic) by Ali Alobaidly, on Flickr

M8 - Nestled in a bed of Gold (4 Panel Mosaic)

Description:
Let us embark on a celestial journey titled "Nestled on a Bed of Gold," a breathtaking 4-panel mosaic capturing the majestic beauty of the Lagoon Nebula (M8) and the Trifid Nebula (M20). Taken from the serene and starlit skies of the Salmy Desert in Kuwait, this image showcases the wonders of our universe through the precise optics of a 382mm refractor and a dedicated astronomy camera.

Imagine standing on the sands of the desert, the vast expanse of the Milky Way stretching above you. The Lagoon Nebula, with its rich tapestry of glowing hydrogen gas and dark dust lanes, appears as a cosmic lagoon, where new stars are born from the nebulous depths. Beside it, the Trifid Nebula, with its characteristic trifurcated structure, stands as a tri-colored beacon of stellar nursery activity. The vibrant reds, blues, and dark silhouettes create a striking contrast, making this nebula a true jewel in the night sky.

But the magic doesn't end there. The myriad of stars scattered across the image forms a golden backdrop, adding depth and brilliance to the scene. Each star, a distant sun, contributes to the mosaic, making the nebulas appear as if they are nestled on a bed of shimmering gold dust.

Zoom in to appreciate the intricate details captured in this high-resolution mosaic. From the delicate tendrils of interstellar dust to the pinpoint brilliance of newly formed stars, every pixel tells a story. The full file of this image offers an immersive experience, revealing the subtleties and grandeur of these deep-sky objects.

For the ultimate experience, I highly encourage you to view the full resolution of this image. Dive into the cosmos, where science meets artistry, and let the wonders of M8 and M20 inspire your imagination. Enjoy the stellar spectacle, and remember, the universe is always ready to dazzle those who take a moment to look up.
