This image is one of the many images that is shown in the video submitted in video submissions section. This particular ISED processed image is able to discern the vortex that is around the black hole in Virgo A (M87). The vortex and black hole is off center to the galactic core.

I am an astro-nerd...and I love this hobby.

This is my first submission in this forum. I present The Pacman Nebula (NGC-281 in SHO). This target was imaged over 3 nights (almost 12 hours) in Northern Virginia using a RASA 8, ASI294MM-Pro, Baader Ultra Narrowband F/2 filters and the ASIAir-Pro all sitting on top of an iOptron CEM-40.

The Pacman is a bright emission nebula located in the constellation of Cassiopeia and is approximately 9200 light years from my backyard.

IC-1805 The Heart Nebula (SHO)

This is one of my favorite nebula. Sitting approximately 7500 light years from my backyard, is the wonderful Heart Nebula (IC-1805). This emission nebula is comprised mostly of hydrogen gas. The open cluster of Melotte 15 can be seen in the center of the Heart and the Fish Head Nebula (IC-1795) in the lower right quadrant. This photo was produced with only 3 hours of imaging.

STORY:
Santa Maria Jump - Iguazu Falls
Photographing Iguazu Falls at night has always been one of my priority projects. For that, it was necessary to obtain a special authorization from the environmental agency responsible for national parks in Brazil. Finally, in early 2021, I got this authorization and set out to put my plan into practice.
I spent 4 days inside the Iguaçu National Park with exclusive access at night to the Falls for me and my students. The first challenge is to walk around the park at night knowing that several jaguars reside there, which are frequently seen by employees and tourists. In the area closest to the main waterfalls, the big challenge is to make long exposure images with the strong water spray from the more than 1.5 million liters per second that fall through the waterfalls. Working with exposure times longer than 10 or 15 seconds became an almost impossible task and the lens was never dry.
In this image we have one of the main waterfalls of the Iguazu Falls complex, the Santa Maria Jump. Immediately over it we can see Jupiter and Saturn and the zodiacal light illuminating the horizon. Further up there is the Milky Way Core with a level of detail and a very good density, taking into account that the capture had an exposure time of only 10 seconds. We can also identify some of the main emission nebulae present in this region of the sky.

NGC 6888 is an emission nebula in the constellation Cygnus about 5000 light years away and 26 light years across.

Here is my 22.1 hour F7 effort on the Edge 11 with the L-Enhance and a small portion done with L-Pro, taken June through August. This was a fun target to image and process.

NGC 300 in full bloom

NGC 300 (also known as Caldwell 70) is a spiral galaxy in the constellation Sculptor. It is one of the closest galaxies to the Local Group. This beauty shows itself full face on and in full HA bloom.
This was done in Chile at SWOS (Stellar Winds Observatory South) using a 24” PlaneWave CDK. The filter set was 5 filters LRGB,HA

Heart and Soul nebulae in the constellation Cassiopeia

Heart and Soul nebulae in the constellation Cassiopeia

The Heart Nebula (IC 1805) located on the right of this image, has a shape reminiscent of a classical heart symbol. To the top of the Heart nebula, lies The Fishhead nebula (IC 1795) is a part of a complex of star forming regions that lie at the edge of a large molecular cloud.

The Soul Nebula (IC 1871) is visible on bottom left of this image. Both nebulas shine brightly in the red light of energized hydrogen.

Several young open clusters of stars are visible near the nebula centers. Melotte 15 (Heart of the Heart nebula) is a popular target.

Light takes about 6,000 years to reach us from these nebulas, which together span roughly 300 light years.

Total integration - 30 hours.

Location - Georgetown, Texas

THE YOUNG GLOBULAR CLUSTER NGC 362


NGC 362 is a globular cluster in the direction of the constellation Tucanae, it is one of the youngest globular clusters, probably forming long after our Galaxy.
NGC 362 can be found with the naked eye almost in front of the Small Magellanic Cloud and angularly close to the second brightest globular cluster known, 47 Tucanae.
Globular clusters offer some of the most spectacular views of the night sky. The Milky Way contains more than 150 of these clusters.
As stars progress through life, they fuse elements at their cores, creating heavier and heavier elements - known in astronomy as metals - in the process. When these stars die, they flood their surroundings with the material they formed during their lifetimes, enriching the interstellar medium with metals. Later-formed stars therefore contain greater proportions of metals than their older relatives.
By studying the different elements present in individual stars in NGC 362, astronomers have found that the cluster has a surprisingly high metal content, indicating that it is younger than expected. Although most globular clusters are much older than most stars in their host galaxy, NGC 362 goes against the trend, with an age between 10 and 11 billion years. For reference, the age of the Milky Way is estimated to be over 13 billion years old.

NGC 4651 by William Ostling, on Flickr

A full write-up is visible here: https://theastroenthusiast.com/ngc-4651-from-hubble/

This remarkable spiral galaxy, known as NGC 4651, may look serene and peaceful as it swirls in the vast, silent emptiness of space, but don’t be fooled — it keeps a violent secret. It is believed that this galaxy consumed another smaller galaxy to become the large and beautiful spiral that we observe today.

Thought I'd post some information on my artwork as discovered it on the 'found images' section of the forum, thanks bystander.
The Cassini missions brought back some astounding imagery from our solar system. I have used a selection of the CICLOPS team's photographs of Saturn to create this piece. The patterns formed by Saturn, it's rings and it's moons are truly magnificent. The photographs have echoes of architecture, nature, art and design and are just as artistically inspirational as they are crucial for scientific study. I edited a number of their most spectacular images before ordering the photographs into a grid pattern and into this particular way to have remnants of familiar and stable imagery but in a fractured and disrupted way, with undertones of science fiction symbolism.

A year ago, after thirty years, I returned to astronomy and was surprised to find out that what we could only dream of in the past can be achieved at home thanks to technological progress. After a year of active study and devotion to astrophotography I am slowly approaching how to take and process astronomy photos. I hope you like it.
This image was taken on my backyard near Bratislava (capital city of Slovak Republic) located in the heart of Europe.

In the constellation Cassiopeia located 7,500 light years away from Earth, is a gorgeous star cluster called Melotte 15.
It lays in the famous Heart Nebula (IC 1805).

The pillar of Cepheus (VdB 152)

This cosmic pillar stretches for approximately 1,400 light years along the northern part of the Milky Way, in the constellation Cepheus. Near the edge of the large molecular cloud, pockets of dust block all light from the stars in the background or weaken the light of the brightest star at the top, this star giving the nebula its characteristic blue color.

At the bottom right of the image is a planetary nebula LBN 538 (red / blue). Discovered in 1979 and first described in an article in 1980 by Dengel, Hartl and Weinberger.

Perfect night at Fortaleza Canyon in Cambará do Sul, Brazil.
Located within the Serra Geral National Park, Fortaleza Canyon is one of the largest in Latin America.
After two rainy nights and a lot of fog, my students and I decided to go up to the Fortaleza lookout for a section on Landscape Astrophotography. Despite the cold and poor conditions at the beginning of the night, after midnight we were awarded with a perfect condition to photograph the Milky Way over one of the most beautiful canyons in Brazil.
