Image Description and Details : This wide field picture features many celestial jewels, including but not limited to IC 4628, NGC 6268, NGC 6231, & NGC 6244. The main object drawing the astronomer attention is most probably IC 4628, a bright Nebula appearing in the constellation Scorpius and located somewhere 6,000 light years from our solar system. Also dubbed the "prawn nebula", it is believed to be a massive stellar nursery, where new stars are forming. Scientists classify it as an emission nebula because its gas has been energized, by the radiation of nearby stars.

Image Description and Details : To make this a little different to the usual red images of this target, I used narrowband filters and processed this in the SHO Hubble palette resulting in a colourful rainbow-like image. The OIII signal was however very faint, so I captured extra data with this, 19 hours in all, resulting in 48 hours total integration time.

NGC 6188 is a dazzling emission nebula located in the southern constellation of Ara, about 4,000 light-years away from Earth. This celestial object is a site of active star formation, boasting a cluster of hot, massive stars that illuminate the surrounding gas and dust with their intense radiation.

Image Description and Details : The M96 group, also called the Leo I group, is a collection of galaxies in the constellation Leo. The group contains between 8 and 24 galaxies, including three Messier objects. It is one of the many clusters in the Virgo supercluster.

M96 is the ‘dominant’ galaxy in the group, i.e. the most massive. M95 and M96 are both barred spiral galaxies, of comparable dimensions and a little smaller than our Milky Way (93 000 AL for M96 and 73 000 for M95).

At the top right is the elliptical galaxy M 105 from the bottom, then Ngc 3384 and then Ngc 3389, the highest in the image.

We can also see a beautiful spiral galaxy (seen – by contrast – from the edge) camouflaged in one of the spiral arms of M96.

Other more distant galaxies can be detected in the picture.

For me as an Austrian these are clearly 2 galaxies dancing Viennese Waltz

Astrophysicists consider NGC 4038 / NGC 4039 as 2 interacting galaxies
at a distance of about 75 million light years in the constellation Corvus.
This pair of galaxies is also called Antennae galaxies, named for the long tails of gas and dust they eject.

Image Description and Details : Messier 106 (also known as M106 or NGC 4258) is a spiral galaxy located in the constellation Canes Venatici, lies at a distance of 23.7 million light years from Earth and has an apparent magnitude of 9,1.
At its heart, as in most spiral galaxies, is a supermassive black hole, but this one is particularly active. Unlike the black hole at the centre of the Milky Way, which pulls in wisps of gas only occasionally, Messier 106’s black hole is actively gobbling up material. As the gas spirals towards the black hole, it heats up and emits powerful radiation. Part of the emission from the centre of Messier 106 is produced by a process that is somewhat similar to that in a laser – although here the process produces bright microwave radiation.
The galaxy has another startling feature; i.e., instead of two spiral arms, it appears to have four. Unlike the normal arms, these two extra arms are made up of hot gas rather than stars, and their origin remained unexplained until recently. Astronomers think that these, like the microwave emission from the galactic centre, are caused by the black hole at Messier 106’s heart, and so are a totally different phenomenon from the galaxy’s normal, star-filled arms.
Messier 106 may have a companion galaxy, the spiral galaxy NGC 4217 (top left in my picture, along with the 3 bright stars). NGC 4217 is about 80,000 light years across and appears almost perfectly edge on.

Image Description and Details : NGC1097 is a splendid barred spiral galaxy, about 45 million light years away and located in the southern constellation of Fornax. It is cataloged as a Seyfert galaxy and at its center hosts a supermassive black hole that is devouring a few billion tons of matter every second.

The object is really interesting to photograph because it has many molecular hydrogen clouds (star formation zones), some of which are positioned in a circular shape right around the galactic center and spiraling around the black hole. The spiral shape is deformed due to the gravitational interaction with some neighboring galaxies: NGC1097A (embedded “perspectively” in one of the two arms) and NGC1097B (farther from the center).

Image Description and Details : The Moon has always fascinated humanity, for its beauty, size and phases.
In 1969, the man managed to walk on it and return safely, overcoming all the challenges of the time.
After this unprecedented landing, there were five more successful missions of manned landings, ending the Apollo Mission in 1972 with the landing of Apollo 17.
Today man is repairing himself to return to the Moon and continue his exploration of this precious satellite of ours.
This photo depicts the regions and dates of the six manned moon landings, symbolizing the golden period of lunar exploration, signaling future lunar explorations.

Image Description and Details : NGC 2170 is a dusty reflection nebula and stellar nursery that formed about 8 million years ago, located at the edge of the giant star-forming molecular cloud Monoceros R2, some 2,700 light-years away. the constellation of Monoceros. The bluish areas are reflection nebulae, so named because they reflect light from nearby hot stars. The red areas are emission nebulae and glow because ultraviolet light from nearby stars excites hydrogen and other gas atoms in the nebula, which then emit their own light in specific colors. What looks a bit like black ink spread across the image are dark nebulae, and are only visible because of the light they block.

Image Description and Details : This is a Narrowband image of NGC 2029, which is an area of emission nebulae in the LMC. This is a modified Sulphur II, Hydrogen Alpha, Oxygen III (SHO) image. The SHO combination, conventionally called the Hubble Palette, maps SII to Red, Ha to Green and OIII to Blue. It does however produce quite garish colours and pink stars.The mix is therefore often modified to give a more aesthetically pleasing image, but one where the abundance of the chemical species is still well mapped in a colour image. After some experimentation I went with:
Red: 50% SII + 50% Ha
Green: 20% Ha + 70% OIII
Blue: 100% OIII
I removed the stars with StarXTerminator, before processing the image. Previously I had removed the natural colour (RGB) stars in processing the LRGB image and I was able to use Pixel Math to add them back to this finished image, to give a much more pleasing star field.
The amazing tendrils of gas come through well in this version and I hope you like it, both for its scientific value in mapping the presence of Hydrogen, Oxygen and Sulphur in this region of the sky, but also for its aesthetics.
