Rho Ophiuchi & Milky Way Core 46 Hour Mosaic

Rho Ophiuchi & Milky Way Core 46 Hour Mosaic by Ahmed Waddah, on Flickr

This image is an integration of 40 panels (46 hours) of the Galactic core and Rho Ophiuchi region. I have spent some time during my imaging sessions this year in Al Fayoum Desert in Egypt collecting data of Rho Ophiuchi using my Rokinon 135mm. I used some old data from the previous year to border the integration and cropped the desired region of interest.

Hello, I am a 15 year old astrophotographer, and still in the beginging fases. This is my Animation of Jupiter, its Great Red Spot, Io, and Europa. It was my first time making an animation of jupiter. I know its not as good as the other ones on this forum, but I am happy with it and hopefully I can get on the APOD.

Rio Caliente Waterfall at Calbuco Volcano

Location: Calbuco Volcano, Lakes Region, Chile
Date: 06 Ago 2023

A few kilometers from the shore of Lake Llanquihue in the town of Ensenada, in an ascent on foot of about 3 hours, you will find the Río Caliente waterfall on the Calbuco Volcano.

This waterfall is characterized by gushing from the bowels of the volcano, thus becoming thermal.

In the photograph we can see how the stars descend from the firmament until said hot river flows through the earth.

Shot these images from a farm on the side of a hill in the Green Mountains of VT. I didn't bring my telescope and tracking rig because i was expecting clouds the entire trip.
However I got one clearish night and decided to take some pictures with my camera. These are all taken with a Nikon Z6 propped on the hood of my car. Used my 24-70mm lens set to 24mm. 15 second exposures with high ISO. Edits in photoshop.

Picture 1 is a shot of the SW sky and the Milkyway coming up over the forest. Picture 2 is basically a shot of the Milkyway straight up toward the Zenith Picture 3 is my favorite. It is a shot of the NE sky. In the foreground is a large barn and a house, with the Green Mountains and fall foliage beyond. In the sky you can see Jupiter, Pleiades, the Alpha Persei Moving Group (MEL 20), and if you look closely you can even make out a redish streak which is the California Nebula. As you can see, even my "clear" night wasn't exactly the clearest of skies. But I think.in some ways the thin clouds add to it.

Hello, I am a 15 year old astrophotographer, and still in the beginging fases. This is my image of Jupiter, its Great Red Spot, Io, and Europa and I am super proud of it. I wanted to see if I have a chance of making it for the APOD.

Rho Ophiuchi
From my backyard in Nowra NSW, I took a four panel mosaic of the stunning Rho Ophiuchi, also known as IC 4604. Situated within the constellation Ophiuchus, Rho Ophiuchi is a visually striking stellar nursery that has captured the hearts of astronomers and astrophotographers alike. It boasts a mesmerizing display of colourful stars set against dark, dusty clouds.
Within the expanse of Rho Ophiuchi, you can find a multitude of celestial wonders, including multiple star systems, protostars in various stages of development, and intriguing objects like the globular cluster M4.
To capture this mosaic, I used 60-80 HaRGB photos, resulting in 4.5 hours per panel totalling 18.0 hours. The images were taken with a ZWO2600MM Pro camera using Antlia RGB and Ha 3nm filters. I stacked each panel with 40 bias and 20 flat frames for each filter. The next step involved stretching the images using the HaRGB method in PixInsight.

Hi friends. Here is my masterpiece. This might be the best image I have ever taken and might be one of the most detailed images I have ever seen of this galaxy. It has 10 times the data of my previous image of this galaxy. In the full image, you can see hundreds of nebulae, countless globular clusters, and even individual stars in the Andromeda Galaxy. The best 28 hours of data was selected to create this image. I was using an 8" f3.9 reflector and an ASI294MM in Bin 1 mode to get this image. I used intensive dithering and drizzle X2 (after considerable testing compared to not drizzling). Full image is 183 megapixels and shows unbelievable detail. Very happy with how it turned out.

I used Astronomik LRGBHa filters and a Skywatcher EQ6R mount.

True color image of the Cirrus nebula (NGC6995) , taken with my 94mm f/4.4 Apochromat and an ASI294MC Pro using a VIS filter for the stars and Dualnarrowband for Ha and OIII.
Ha and OIII are weighted in the linear space according to the relative sensor sensitivities and then given those colors, which are a best fit for representing 501nm and 656nm on a PC monitor in sRGB. This is the correct color, that you would see, if the nebula was simply bright enough.
The stars are taken from a different exposure batch in the VIS spectrum.

The Ghost of Cassiopeia

https://cdn.astrobin.com/thumbs/-KY8blv ... TZ0INm.jpg

In this image we find 2 diffuse nebulae IC63 (the ghost) and IC59, Gamma Cassiopeia (the blue lighthouse) and some dark nebulae.
The nebulae appear to us to be mainly red and a little bluish in some regions.

• The red reflects the emission of photons (red) by the nebula's hydrogen atoms previously ionized by Gamma Cas radiation.
  The blue is the diffusion by reflection of the radiation from this same star.

The image is not easy to process: Gamma Cas is very bright, it dazzles the scene and drowns out the dark nebulae around it.
The 1 second exposures revealed the stars in the field near Gamma Cas.

LDN 1235 and LND 1251 - The eternal chase by Ali Alobaidly, on Flickr
https://live.staticflickr.com/65535/532 ... f5a4_k.jpg

Image description:
In the boundless tapestry of the cosmos, a mystical dance unfolds—a poetic tale of an eternal chase. Two enigmatic silhouettes, both formed from the cosmic ink of dark nebulae, engage in a timeless pursuit across the velvety expanse of the night sky. The predator, a shadowy monster, lurks with a voracious hunger, its inky form resembling a celestial shark. Its essence, a whisper in the fabric of the universe, pulses with the unseen gravity of a cosmic maw. It prowls the cosmic ocean of stars, hunting its ethereal quarry with relentless tenacity.

The prey, a celestial fish of eldritch beauty, hidden as though woven from the dreams of distant galaxies. Its form dances gracefully between the constellations, a wavering apparition, elusive and yet fearful. Each flick of its spectral tail leaves behind a trail of stardust.

As the predatory shadow glides through the night sky, its dark tendrils stretch like cosmic jaws, yearning to enshroud the ethereal fish in its inky embrace. Yet, the fish is a master of evasion, darting through the astral waters, weaving between stars like a phantom, leaving behind oceans of dust, the stuff of light, fission and fusion.

This eternal ballet unfolds, a dance of cosmic shadows, a timeless allegory of the universe's undying drama. Across the infinite canvas of the night sky, a tale of an enduring chase, woven into the very fabric of Cepheus.

The Moment Before Annularity
This image shot with a dedicated H Alpha solar telescope, captured a moment filled with great anticipation. The Moon was about to centre itself on the the face of the Sun for a full annular eclipse. Solar prominences and sunspots are visible in the chromosphere. Shot under lovely New Mexican skies in Albuquerque on October 14th 2023.

Hello everyone, When a Canon EF 300mm f2.8L USM lens, more than 30 years old, offered by my friend Mikl Paqz, meets a latest hybrid camera from Canon, the R6, it gives us images that are on fire! And on this occasion again we needed a small onion framing with a framing at 300mm I wanted to image the heart nebula (in the middle), the soul nebula (top left) and its extensions, as well as an HB3 supernova remnant here in this instance (bottom right) which is material ejected during the explosion of a star in a supernova. All this was also possible to be highlighted with only 12 hours of exposure on a very beautiful bortle 3 sky in the Landes and the magic of Philippe Bernhard's treatment with a HOO palette foraxx treatment.

The 2023 Annular Eclipse over Stonehenge in Odessa, Texas
Copyright: Alson Wong The 2023 annular solar eclipse passed over portions of North and South America, including Odessa, Texas, which has a replica of Stonehenge at the University of Texas Permian Basin that is 70 percent of the size of the original monument in England. This images is a composite of 37 separate exposures of the Sun, and an exposure of the monument taken at dusk from from the same location the day before.
