Image Description and Details :

I'm very proud to present this photo in L-HOO which required a total exposure of 27 hours per 20 minutes per photo, spread over 7 nights of the month of May, not counting the 10 hours of image calibration. At a magnitude of 14.74, it is very little luminous, which makes it difficult to image it.

It is located in the constellation Cepheus at a distance of 980 light-years.
Sh2-174 is one of the oldest planetary nebulae that is more unusual because the white dwarf is not in the center of the nebula. This asymmetry is due to the interaction of the planetary nebula with the surrounding interstellar medium.

This image shows the rising Seagull Nebula soaring high above Mt. Druesberg in central Switzerland.

The Seagull Nebula is an emission nebula on the borders of the constellations of Monoceros and Canis Major. Its location 10 degrees below the celestial equator puts it rather low for northern hemisphere observers, which may be the reason why it is not as famous as other nebula that rise higher during the night.

For deepscapes however, a deep space object needs to hug the horizon, which makes the Seagull Nebula a perfect target.

Despite careful planning, the resulting image contains a big surprise: The Seagull Nebula is not that splendid bird with a bright body and wispy wings and tail you can see in this deep image. I didn't even know that these structures exist. What is known as the Seagull Nebula is just the bright body part that remotely resembles a soaring bird on its own - it is the bird in a much bigger, more detailed bird! How awesome!

Image Description and Details :

Another bright planetary nebula to capture during a full moon.
NGC 1501 is a complex planetary nebula in the constellation Camelopardalis.
It's progenitor star is a pulsating star, meaning that its brightness varies regularly and periodically. In the case of NGC 1501’s progenitor star, this is incredibly fast, with the star’s brightness changing significantly in just half an hour.

This portion of the Milky Way in the southern hemisphere is very rich in nebulae and some star clusters, my favorite constellation "The southern cross" with its beautiful stars (Acrux, Mimosa, Gacrux and Imai) are the 4 main stars that they form this constellation which serves to find the south cardinal point by moving the central axis of the "cross" 3 and a half times.

We can also see the nebula of the keel or eta carina and below the cross the sack of coal or head of the "Choique" as the Mapuches knew it.

While taking these photos I was able to observe the passage of the International Space Station next to some Russian polar orbit satellites in the province of Rio Negro.

Image Description and Details :

Just below the teapot of Sagittarius in Corona Australis lies a strikingly-beautiful region containing several objects of widely differing ages and distances. Exquisite blue reflection nebulae (NGC 6726/27), lit by the embedded bright stars TY CrA and HD 176386, and IC 4812 (HD 176269 and 176270) appear to be connected by wispy blue filaments that span the dust lane SL-41. Nearly 200 lys closer than those stars, the wing-shaped nebula (NGC 6729) below those filaments is energized by the 310 ly distant R CrA. Closer still is the bright blue eclipsing binary star at the upper right, epsilon CrA, at 102 lys, which along with the far more distant globular cluster NGC 6723 span the "depth" of this 53-arcmin x 53-arcmin scene. The image was made using ten minute guided exposures taken through red, green and blue filters by an unbinned FLI ProLine 16803 camera mounted on Chilescope’s 0.5-m Telescope 2, which were stacked for 1-hr; north is left, and east is down.

The Iris Nebula is a reflection nebula in the constellation Cepheus, which is actually a patch of interstellar dust illuminated by a blue star. In the 2-panel-mosaic wide-field image, you can see that this area of the sky is actually filled with interstellar dust, but the other dust is not illuminated by nearby stars like the Iris Nebula.

Located in the direction of the Orion constellation about 1600 light-years, its apparent size is slightly larger than the full moon.the monkey's head nebula or simply NGC 2175 is an emission nebula that emits in different wavelengths mainly in HA but also in Sii and Oiii.In the center is the star catalogued HD 42088 which emits a strong ultraviolet radiation that ionizes the gases in the vicinity.In addition to ultraviolet radiation, this star emits powerful stellar winds that shape the nebula's gas cluster, helping to create several pillars (visible in the image) that form a star nursery.Technical data:- Takahashi fsq 85 F/D 3.8- iOptron cem60 ec mount- Zwo asi 1600 mm cooled pro- 130x300s HA : 10h50min- 145x600s OIII : 24h10min- 30x3x60s RGB : 1h30 min- Total integration: 36 hours 30 minutes- DOF: 27x101x35- Date: January 2021- Location: Ben Slimane MAO Observatory, Morocco.

Image Description and Details : I wanted to share this photograph taken during the last total solar eclipse on December 14th.During the last total solar eclipse, in La Lobería, Río Negro, Argentina, on the edge of the South Atlantic and its immense cliffs, which helped to compose the image that I present here, 4 planets could be observed with the naked eye, some stars, and others could be captured with a long exposure photograph. The photography is the result of a composition of two images, one with a long exposure to capture the stars (where the eclipse was overexposed) and the other with a short exposure (with the eclipse well exposed).Cámera: Canon T3Lens: Tokina 11-16, in 11 mm F: 7.1 / 5.6ISO: 200 / 3200Exposure: 2 shots: 10 seconds and 1/20 seconds Software: Photoshop.

Image Description and Details :

This image shows the Orion Nebula, De Mairan’s Nebula, the Horsehead Nebula and the Flame Nebula. It was taken with a small refractor telescope from the city. For this, narrowband filters were used and long exposure times helped reveal a lot of gas and dust all around the nebulae. The color was achieved by combining the narrowband channels into a “OHS” combination. This is rarely done and gives this part of the sky a unique look. Other combinations (Hubble Palette or true color) did not really make the objects pop as much. I believe the OHS combination is the best when it comes to imaging this section of the sky in narrowband only, although it is either you love it or you hate it!

NGC 3189 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.
