At the remote heart of the Ophiuchus constellation, LDN 43 emerges like a dark wound carved into the starry fabric of the Milky Way. It is a dark nebula, made not of light, but of absence. A silent presence that imposes itself by subtracting luminosity, veiling everything behind it with primordial dust.
This image was born from a challenge: to make the invisible visible. Photographing a dark nebula means working in the depth of darkness, where light is scarce, signal is subtle, and every step in post-processing risks disrupting the fragile balance between realism and perception.
Denoising becomes a double-edged sword. Too aggressive, and the fine grain of interstellar dust vanishes; too weak, and noise creeps in, blurring the line between what is real and what is digital artifact. Contrast must be applied with equal restraint: push it too far and the ethereal gradients are broken; hold back too much and the image feels flat, void of depth and dimension.
Every step was taken with respect for the subject, as if the nebula itself had asked not to be forced into visibility, but only whispered into existence. I approached this image more through subtraction than enhancement, allowing its darkness to speak, without trying to illuminate it fully. Because LDN 43 is not seen through light, but through silence.
Clear Skies.

Located in the constellation of Ophiuchus, this nebula strongly resembles a bat, so it was quickly nicknamed The Cosmic Bat nebula. LDN 43 is a dark nebula and star forming region, that contains the reflection nebula RNO90 and RNO91, that are illuminated by young stellar objects. LDN 43 is one of the closest star forming regions lying at about 1400 light-years distance.
In the middle lower part of the image, next to a yellow star, LEDA 3868080 can be seen. This galaxy lies over 400 million light-years from and is slightly larger than our galaxy.

Soaring silently across the Opiuchus constellation, LDN 43 stretches its cosmic wings against a canvas of starlight. This dark nebula is composed of thick interstellar dust that obscures the background stars, creating the silhouette of what resembles a celestial bat in flight.
But this bat isn’t just made of shadow - within its dark folds, new stars are being born. LDN 43 is part of a complex region of star formation, where gravity pulls dense dust clouds together until nuclear fusion ignites. The surrounding golden and blue hues come from background stars peeking through less-dense patches of dust, subtly illuminating the edges of this celestial phantom.

Don’t be fooled by the title; the mysterious, almost mystical bright light emerging from these thick, ominous clouds is actually a telltale sign of star formation. Here, a very young star is being born in the guts of the dark cloud LDN 43 — a massive blob of gas, dust, and ices, gathered 520 light-years from Earth in the constellation of Ophiuchus (The Serpent Bearer).
Stars are born from cosmic dust and gas, which floats freely in space until gravity forces it to bind together. The hidden newborn star in this image, revealed only by light reflected onto the plumes of the dark cloud, is named RNO 91. It is what astronomers call a pre-main sequence star, meaning that it has not yet started burning hydrogen in its core.
This image is based on data gathered by the NASA/ESA Hubble Space Telescope. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.

🌌 LDN 43 – The Cosmic Bat Nebula ✨

Emerging from the darkness of interstellar space, LDN 43, also known as the Cosmic Bat Nebula, is a striking dark nebula in the constellation Ophiuchus. Its dense clouds of cosmic dust obscure the background stars, creating an eerie silhouette reminiscent of a bat in flight.
🔹 A Stellar Nursery: LDN 43 is a star-forming region where young protostars are taking shape deep within its dusty cocoon.
🔹 The Power of Darkness: Unlike emission or reflection nebulae, dark nebulae are visible not because they shine, but because they block light from stars and nebulae behind them.
🔹 Hidden Protostars: Inside LDN 43, infrared observations have revealed the presence of forming stars, their light struggling to escape the thick veil of dust.

A flying bat in Ophiuchus.
Cruising around at a distance of around 1400 light years from us is LDN43 - the Flying Bat. It is beautiful example of a dark nebula and a stellar nursery for newborn stars.
Gerry Im from Astrobin wrote a very fine description.
“Two cometary nebulae are seen at the center of LDN 43. The first, GN 16.31.7, is the brightest yellow object at center, lit up by the hidden young star RNO 91. Slightly above and left is the 2nd cometary nebula, GN 16.31.3, lit up by RNO 90. The small galaxy seen below LDN 43, just to the left of a bright orange star, is LEDA 3868080. This galaxy is located 400 million light years away. It is slightly larger than our Milky Way, at about 130,000 light years in diameter. This background galaxy is 400,000 times further away than the foreground nebula.”
I had hoped to spend many nights on this target over the new period from LMDSS but alas the weather changed and the winds on the only clear night impacted every light frame in my data. Hopefully next month will be better.

Kaleidoscopic version of a Hubble Space Telescope image of a star being born inside of a dust cloud.
Original caption: Don’t be fooled by the title [Sunset in Mordor]; the mysterious, almost mystical bright light emerging from these thick, ominous clouds is actually a telltale sign of star formation. Here, a very young star is being born in the guts of the dark cloud LDN 43 — a massive blob of gas, dust, and ices, gathered 520 light-years from Earth in the constellation of Ophiuchus (The Serpent Bearer). Stars are born from cosmic dust and gas, which floats freely in space until gravity forces it to bind together. The hidden newborn star in this image, revealed only by light reflected onto the plumes of the dark cloud, is named RNO 91. It is what astronomers call a pre-main sequence star, meaning that it has not yet started burning hydrogen in its core. The energy that allows RNO 91 to shine comes from gravitational contraction. The star is being compressed by its own weight until, at some point, a critical mass will be reached and hydrogen, its main component, will begin to fuse together, releasing huge amounts of energy in the process. This will mark the beginning of adulthood for the star. But even before this happens the adolescent star is bright enough to shine and generate powerful stellar winds, emitting intense X-ray and radio emission. RNO 91 is a variable star around half the mass of the Sun. Astronomers have been able to observe the existence of a dusty, icy disc surrounding it, stretching out to over 1700 times the distance from Earth to the Sun. It is believed that this disc may host protoplanets — planets in the process of being formed — and will eventually evolve into a fully-fledged planetary system. This image is based on data gathered by the NASA/ESA Hubble Space Telescope. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.
