Andromeda in Hydrogen alpha

Credit: Andrea Bergamini and Sameer Bharadwaj

This is a blend of only 90 minutes of RGB color data with over 15 hours of Hydrogen alpha data. Goal was to bring out as much as possible both the hydrogen alpha emission nebulas in the 'foreground' coming from our own galaxy and the ones inside Andromeda itself.

South of the star Antares in the nebula-rich constellation Scorpius lies the emission nebula IC 4628 - the Prawn Nebula.
This is a close-up of the central region. In the image field there are also 2 brilliant open clusters and more.

NGC-1579 is a diffuse nebula located in the constellation of Perseus and also in the California Molecular Cloud.

I was able to get over 37 hours of imaging on this one and lightly processed in PixInSight. My goal was to bring out the dark dust in that surrounds the target.

The Horsehead Nebula (Barnard 33) and surroundings. OSC camera.

This image consists of a composition between a 7h integration image with an UV/IR filter and a 3.5h integration image with a Duo-Narrowband filter to pull some of the faint h-alpha details.
The blending process is always a trial and error quest until the sweet spot Is reached.
For my taste I find it beautiful to make those faint nebulosities around Alnilam to pop up, like IC426 For example.
There’s more to appreciate in this image than the obvious horsehead/flame/ngc2023 trio.

Orion's treasures behind the observatory's Dome
Location : Cairo, Egypt

Kottamia Observatory is the largest telescope in the Middle East and North Africa. The telescope, which is located 80 km from the center of old Cairo, has a main mirror diameter of about 1.88 meters (74 inches) and weighs about 2 tons, The diameter of the dome is about 19 meters, and weighs more than 100 tons.

Light pollution is following us and Killing our observations, and in the upcoming few years the area around this observatory will be at 6-7 Bortle scale at least

The Helix Nebula

Click to view full size image

The Helix Nebula is a stunning deep sky target that was created as a result of a star near the end of it's life cycle expanding and shedding gas. The shells of expanding gas created the beautiful planetary nebula structure we can observe with telescopes. This evolution for the majority of stars in the Universe will also occur to our beloved Sun one day. I captured this 50-hour data set with a PlaneWave Instruments CDK600 at ObsTech using Voyager automation software. Camera used was a QHY600. HA = 43x30min, L = 177x5min, and RGB = 55x5min per channel.

Here is the CG4 area that I did from a set of 2 Advanced Requests through Telescope Live. I framed it in a way to also get NGC 2427. I've wanted to attempt this one since I first saw it a few years ago.

This was acquired via the Telescope Live CHI-2 setup, then processed in APP and Photoshop. It consists of 6x 300s each of RGB, 8x 300s of L, and 8x 600s of Ha, for a total of 3.5 hours of integration.

My Panorama image for Milky way taken in 18 th of November 2022 . I drove 5 hours away from home to Dark sky to be able to capture this image. The panorama is of 49 Panels . All images were taken about 90 minutes after sunset to be able to image a large part of the Milky way arc with Pleiades, California , North America ,Pelican , Elephant trunk , Heart ,Soul , Crescent nebulas and Sadr region. At the far right side you could see a group of EGYPTIAN astrophotographers deploying their gears to shoot the starry sky and to the far lower left side you could see my shadow with the tripod and it reminds me of Armstrong Shadow in the very famous image of Apollo 11 mission after landing on the moon. All images were shot by same gears in same place at same night.

Dear Professor Robert J. Nemiroff, dear Professor Jerry T. Bonnell,

I hope you are both well.

By means of this email, I would like to submit an image for the NASA Astronomy Picture of the Day (APOD): https://flic.kr/p/2o2act6

The photo was taken on 13 December 2020, 07:35 am CET, on the Pont des Arts, overlooking the Pont Neuf and Ile de la Cite, 75006 Paris, France. The photo was taken before the sunrise, which was scheduled at 08:36 am on 13 December 2020.

I read and re read the NASA article "What's Up - December 2020", and from what Mr. Tony Greicius writes, I am extrapolating that in this photograph, I was able to magically capture 4 planets at once: Jupiter and Saturn (in the top left, closer in the sky than they have appeared in 2 decades) and the old crescent Moon and the planet Venus (on the top right).

Doing more background research I came across another photograph in the NASA Archive for Astronomy Picture of the Day listed on 14 November 2020, that is similar to mine, taken on 13 December 2020. It is the image labelled "Venus, Mercury and the Waning Moon": https://apod.nasa.gov/apod/ap201114.html

Is it possible that my photo, in the quality in which it is attached, could be enhanced?

Is it also possible that it could be labeled as "citizen science"?

Best regards,

Mascha Samkova

"The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.

It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements."

This photograph was taken from the top of the Dune du Pilat (Gironde), looking west towards the Atlantic Ocean. Located between the Landes forest and the Arcachon basin, the Dune du Pilat is the highest dune in Europe..... Not easy to climb to the top at night with all the photographic equipment..... But the effort was worth it!

On a good part of the sky are visible "orange clouds"... ? This is called "airglow", a natural phenomenon caused by a chemical reaction in the upper atmosphere, where the sun's rays excite the molecules, which then emit a very weak light (chemiluminescence) of green or orange colour. This phenomenon can only be observed under a clear sky, free of light pollution, which is the case here towards the west, towards the ocean. Moreover, it is not or hardly visible on the left of the image, because of the light pollution of Biscarosse.

Beyond the Airglow and the Milky Way, we can see Jupiter (far left), and to its right Saturn, Altair and Vega. A nice alignment, especially since Jupiter, the largest planet in the solar system, was very bright (one month after its opposition).

On the left side of the image, you can see a part of the Landes de Gascogne forest. This forest was made infamous this summer because of a terrible fire that destroyed more than 20,000 hectares of nature... We become even more aware of the fragility of our small planet in the face of the immensity of the universe.

At the beginning of 2022 I left in the Cantal France (800km A / R only place where the weather was nice) to image on 2nights the constellation of Orion at 135mm, the first treatment was a little too artistic, so with Philippe Bernhard, during the astronomy weekend with the association and with the bad weather it gave us time to start all over again!

Messier 91 – NGC 4548 - HST
Messier 91 (also known as NGC 4548 or M91) is a barred spiral galaxy found south of Coma Berenices. It is in the local supercluster and is part of the Virgo Cluster of galaxies. It is about 63 million light-years away from our galaxy. It was the last of a group of eight “nebulae” – the term ‘galaxy’ only came into use for these objects once it was realized in the 20th century that they were extragalactic – discovered by Charles Messier in 1781. It is the faintest object in the Messier catalogue.

Several hours post process.

IC 434 is an emission nebula visible in the constellation Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.

At the bottom left we find NGC 2023, a small nebula that shines by reflection of the light produced by the star HD 37903, of spectral class B5, from which it takes its markedly bluish color; this is the southernmost illuminated part of Orion B.

At the top left enters the blue light of the star Alnitak, one of the three stars in Orion's belt
