Re: Submissions: 2024 February
Hello
Here is my submission:
Polaris IFN with some friends lost in the dust

Blue 4×300,″(20′)
Blue 15×600,″(2h 30′)
Green : 5×300,″(25′)
Green: 21×600,″(3h 30′)
Red : 4×300,″(20′)
Red : 21×600,″(3h 30′)
Lum : 8×300,″(40′)
Lum : 20×600,″(3h 20′)
Intégration: 14h 35′
Integrated Flux Nebulae (IFN) are extremely faint, diffuse structures of interstellar dust illuminated by the integrated flux of nearby stars. These nebulae are challenging to observe and photograph due to their low surface brightness, making them elusive in traditional visual observations.
These IFN are predominantly composed of microscopic particles such as carbon and silicate dust, scattered throughout the interstellar medium. Unlike traditional emission or reflection nebulae, IFN does not emit light itself but becomes visible through the scattering of starlight by the dust grains it contains. This scattered light creates a subtle glow that can be detected only with quite long-exposure. Despite there isn't actually a map of where to find IFNs, some places are well known, like this one around Polaris.
I wish I could have chosen better exposure times. 600s is too much for this target, so the core was saturated. Even the 300" ones were too long. Even with the HDR composition the core was still saturated in a tiny zone around center
I aimed to create, with this image, an impression of softness combined with a certain icy atmosphere, unconsciously referencing the "Polar," while maintaining saturated stars, which are almost the sole contributors of color to this ambiance.
There are also tiny gems hidden in the dusts, like NGC3172.
Hope you enjoy it.

The Llanquihue National Reserve is one of the oldest protected wild areas in the country, it was created in 1912 and is located in the Andes mountain range, in the province of Llanquihue, communes of Puerto Varas, Puerto Montt and Cochamó, in the Region . of Los Lagos. Geographically it is located west of the Reloncaví estuary, in the mountainous area it extends north of Lake Chapo.
It is part of the Temperate Rain Forests of the Southern Andes Biosphere Reserve.
We can appreciate the impact on the vegetation and its erosion, resulting from the eruption of the Calbuco volcano in 2015.

Re: Submissions: 2024 February
The Angel Nebula and the dust clouds of Monoceros
contain many interesting deep sky objects, principally NGC 2170 which is often interchangeable as a name.
NGC 2182, NGC2167 can also be seen in this deep, wide field shot. I also wanted to include VdB70 which is the red disk seen at the top right in this image.
This is the first image I've completed since having surgery in January, and it amazed me how much energy that sapped ! Many evenings I was too tired to care and with some pesky problems with my mount, I found that my problem solving skills were at an all time low.
However, that has now improved dramatically and my mojo has returned
The angel is getting lower and lower in the sky so I don't think I'll have chance to add more data this season, so this image is plain RGB.

About me: My name is Rod Prazeres, an amateur astrophotographer from Brisbane, Australia. I started my Astrophotography journey in July 2023, and have been more and more excited about the journey ahead. It’s a steep learning curve but I am enjoying every step of the way - except the cloudy nights.
Today we're diving on my first target of 2024 - the Seagull Nebula, a fascinating spectacle in the winter sky. Located on the border between the constellations Monoceros and Canis Major, this nebula offers a stunning view resembling a seagull in flight.

While some may process this image in SHO or using a beautiful red palette in HOO, I decided to combine the best of both worlds. I processed this image in Foraxx SHO, which gave it a really nice red wavelength, but darkened the more subtle parts of the nebula. So I also processed a SHO version of the image highlight those dim areas, then I used the SHO as a luminosity layer and combined the two, which brought those dim areas to life. The result is a portrait of the Carina Nebula that not only captures its inherent beauty but also highlights the photographer’s innovative spirit in the face of astronomical photography’s challenges.

"The Witch"
The Witch by Ahmed Waddah, on Flickr
This is the Witch Head Nebula in HaRGB, a reflection nebula in the constellation Eridanus, the nebula is believed to be an ancient supernova remnant or gas cloud illuminated by the superstar Rigel in the constellation of Orion. I had imaged this target a couple of times before, but I really wanted to capture it in mono. I imaged the target over 6 nights in January and February. After collecting my RGB data and processing the data I decided to add Ha data instead of Luminance to add more red the background of the Witch Head and make it pop against the background. I did use a synthetic luminance from the combined RGB. Also data was drizzled x2 to enhance details. I am very satisfied with the result I got, and I must have processed the data like 8 times before reaching this final edit. I am glad to share this with the astro community.
Each month I travel 4 hours outside of Cairo to a Bortle 2 location in Al Fayoum desert to do my astrophotography. So I do 2-4 imaging nights each month when cloud condition allows.

Description: NGC 3521 is a barred spiral galaxy in the constellation Leo, about 26 million light-years away from Earth. It has unusual “flocculent” arms that are irregular and fragmented. This means that its spiral arms are not smooth and continuous, but consist of many dust clouds and young star clusters. These arms create a beautiful contrast with the bright and round core of the galaxy, which contains a region of H II and low ionization. NGC 3521 also has streams of stars that originated from smaller galaxies that it absorbed in the past. NGC 3521 was discovered in 1784 by the famous astronomer William Herschel

Re: Submissions: 2024 February
Sharpless 2-261 is a faint emission nebula located near the outer edge of the Orion arm of our Milky Way Galaxy. Named for the father-son team of astronomers who discovered it in 1939, it is simply classified as an HII region. It is energized by a rogue O-type star identified as HD41997 travelling rapidly through the surrounding material. It contains a unique multi-layered bubble or shock wave forming in the center of this nebula. It appears similar to bubbles formed around Wolf-Rayet stars but no such stars are known in this area.

Venus and Mars will align in the sky, passing 38' to the north of each other
At roughly the same moment, the two objects will make a close approach, known as an appulse.

man Vs the universe showing how small we are comparing to the mighty milkyway core
I took this image on a magical night full of stars witha canon 6d astro modified and a 85mm Sigma art lens
it was taken in 2020 in august when the milkyway is stright for a protrait shot i hope you like my new editing

NGC 6888 in high definition
Full version : https://cdn.astrobin.com/thumbs/JqETqYP ... TZ0INm.png
Full version : https://cdn.astrobin.com/thumbs/k8Z0P1p ... TZ0INm.jpg
The Crescent Nebula (NGC 6888) is an emission nebula in the constellation Cygnus, around 5,000 light years away.
This envelope of matter is produced by a very special type of star, a "Wolf-Rayet star", named after the two astronomers from the Paris Observatory who discovered this type of star using spectroscopy in 1867: these are hot stars, probably the offspring of stars of spectral type O and B (i.e. the hottest and most massive stars in existence) that have just left the main sequence and are therefore entering the final stages of their lives.
The Crescent, visible in the photograph shown here, represents the zone of influence of the stellar wind from the central star WR-136, whose surface temperature is extremely high, estimated at 70,000K. The size of this bubble is considerable, extending over 25 light-years! By way of comparison, the Sun's heliosphere, i.e. the zone of influence of its solar winds, is no more than 12 light-years long.
The material making up the envelope was ejected from the star 400,000 years ago, so we can estimate its current expansion speed at around 50 km/s. At the time of the ejection, however, the speed was much higher, estimated at 1400 km/s.
Astronomers estimate that WR-136 should explode as a supernova in the "near future" (on the scale of the Universe), in 100,000 to 1 million years.

A cosmic helmet!
Thor's Helmet, given its similarity in shape to the Norse god's famous headwear is an emission nebula located 12,000 lightyears away in Canis Major catalogued as NGC2359.
The nebula originates from a scorching Wolf-Rayet star ejecting a flow of charged particles termed a stellar wind, which expands outward to form an interstellar bubble. This bubble interacts with adjacent molecular clouds, inducing ionization by radiation, thereby illuminating the nebula.
Equipment used:
Skywatcher Esprit 120ED
ZWO ASI294MM Pro
Skywatcher EQ6R Pro
Astronomik Ha and Oiii filters
Total Exposure: 10h
Dates: 2/3/2024, 2/5/2024, 2/14/2024

The X.6 Class Solar Flare Player
This sparky sunspot region AR3590 has been travelling across the face of the sun all week sending out some of the biggest solar flares so far this solar cycle, including the X .6 flare earlier this week. Using your solar eclipse glasses you could see this giant sunspot from earth without a telescope
The unstable magnetic fields in this sunspot are more becoming and more common as we approach solar maximum.
Imaged with a Quark chromosphere solar filter Feb 25th, 2024. A monochrome planetary camera was used and false colour added in Photoshop
