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.

Image Description and Details : NGC 1514 is a planetary nebula in the constellation Taurus. It is also known as the Crystal Ball Nebula. It is 1520 light years from Earth. The nebula originated from a binary star system with the designation HD 281679 from the Henry Draper Catalogue. The bright, visible component is a giant star, while the nebula-generating companion is now a hot, sub-luminous O-type star. The two have one of the longest known orbits for any planetary nebula, with a period of about 9 years.

Image Description and Details : The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant in the constellation of Taurus. Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion.

At an apparent magnitude of 8.4, comparable to that of Saturn's moon Titan, it is not visible to the naked eye but can be made out using binoculars under favourable conditions. The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 6,500 ly from Earth. It has a diameter of 11 ly.

At the center of the nebula lies the Crab Pulsar, a neutron star 28–30 kilometres across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves.

Image Description and Details : This is easily one of my most ambitious astrophotography projects to date. Given that I’m fairly limited by my dslr in terms of imaging very dim objects, I decided to dump as much time on Orion as possible to see how much dust and gas in the region I could reveal. I was struck by how much wispy H-alpha gas didn’t line up exactly with the dust in the region – it was very cool to see the differences in ionized and non-ionized gas.

Image Description and Details : Gassendi, an amazing crater.
Normally, when we start astrophotography, our first target is the Moon. Our old Lua is generous because it works well even on the most modest instruments. A simple 60mm scope and a cell phone already allow for interesting photos.
But shooting the moon in high resolution requires good apertures, proper collimation and a dedicated camera, and it can be difficult work if the photo is close to the terminator.
But, in fact, it is the photos close to the terminator that reveal the good lunar photographers, as they require adequate control of light, both at the time of capture and in subsequent processing.
In this photo we have Gassendi very close to the terminator, and with the sun at an extremely low angle, the relief of the floor stands out in a dazzling way. Its rhymes are usually very evident but with the sun low we can clearly see how irregular the floor of this remarkable crater is.
Gassendi is one of the main lunar craters, with its 114 km in diameter, it is very old formed in the Nectariam period about 3.92 billion years ago.
It is an impact crater with Fractured Interior (FFC), which was modified by volcanic action after its formation, probably huge lava flows gushed through the cracks in the floor, causing numerous stress fractures to form in its interior from the reservoirs. of lava, this made it quite shallow in relation to its diameter - just 2.8 km deep.
When observed through spectroscopic analysis, the Gassendi crater has a "behavior" very different from any other lunar crater (Mikhail 1979). High-resolution studies performed in near-infrared light (Chevrel and Pinet 1990, 1992) indicated the presence of extrusive volcanic material (that is volcanic material that flows to the surface and then crystallizes) limited to the adjacent southern part of the Gassendi floor. to the floor of the Mare Humorum.
Interpretation of the data also suggested that major extrusive volcanism may have occurred in the eastern portion of the floor, as indicated by the significant presence of pyroxene, which corresponds to visible volcanic features. The western part of the crater floor, away from the geometric continuation of the western rim of Mare Humorum, is composed of rich upland material.
The difference between the west and east sides of Gassendi with intensely fractured soil could be strongly linked to the early thermal history of Mare Humorum.
I've already taken countless photos of Gassendi, but the result of this one with the sun very low really surprised me. A pleasant surprise, which shows that each photo is unique in itself and each moment is unrecoverable if we don't know how to take advantage of it.
