California Nebula

California was too hot to handle! I shot this back in February of 2022 at -30 degrees celsius, but the weather warmed up the next day and I was unable to get the camera cold enough until now(Nov 2022). In the time in between I have replaced almost all the gear I use and will be selling this scope, camera, and filter set off soon, so I think it is only fitting that my last light on the Redcat 51 is presented here in this HSO palette in all its red glory. Shot from Vancouver, Canada from my Bortle 8/9 rooftop.

NGC1999 and M42

The main actor of the picture should be NGC1999 but the Orion Nebula is too big.
A lot of work (as days) to acquire all frames used in this picture. Mixing mono and color camera data with wide and narrow band filters.
The data with L-Ultimate filter is divided in HA and O3 and the HA is integrated with the mono camera session.
The result is an HA O3 LRGB image

ImageM45: The Pleiades by Harley Grady, on Flickr

The Pleiades is a an open star cluster approx 444 light years away and is located in the constellation Taurus . It is one of the brightest star cluster in the sky, easily visible even in some moderate light polluted areas. After sunset just look towards the east and you can see this beautiful star cluster.

The Orion season begins. In the southern hemisphere, this constellation becomes visible during the summer. A thin layer of clouds blurred the stars and brought out their colors. In the picture we can see M45 (Pleyades), Mars, the Hiades and Aldebaran, the Orion constellation in full with its main stars and Orion's belt, to close ranks with Sirius.

Here is an image I would like to submit for APOD.

I was never a huge fan of this target, which is exactly why I decided to spend many nights capturing it in the hopes to reveal unexpected nebulosity or features. I was not disappointed!

This is 54 hours on the Pacman Nebula (NGC 281). There is so much gas expelling from the nebula, and a ton of hydrogen alpha all around the object. I spent 3 hours on RGB for the stars and 51 hours on SHO. The structures visible in the expelling gases are very interesting, and the Bok globules are very defined.

Rise of Orion

Image
Rise of Orion by Martin Giraud

IG : https://www.instagram.com/tinmar_g/

Here is a picture I shot of Orion rising above the mountains.

I’m particularly proud of this one because I always wanted to photograph something like this but I only got a few possibilities to do it until now. Indeed the Orion period is mainly during the winter time and here in France it’s clearly not the best time for the weather. Indeed I live in Paris so I have to plan ahead trips to take astrophotography and during winter because of the cold and the clouds sometimes it’s very difficult…

So last weekend I had the chance to plan a session in the south of France at the Cosmodrome Observatory. Despite the cold weather being very good, we didn’t get any clouds. The observatory is perched at the top of the mountain at 1400m, the temperature was -2°c but the feeling was -7°c because of the wind. In those conditions it’s not alway easy to do things well.

For this picture I waited for Orion to be revealed and I shot the landscape where it was then I shot Orion in the sky while it was rising with the equatorial mount. So it’s a composition of two pictures where each is a stack to reduce noise with following settings :
Foreground : 10 pics with ISO-4000 - F2.8 - 45 sec
Sky : 98 pics with ISO-2500 - F2.8 - 45 sec

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

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.

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!

The sky, between land and sea
flickr : https://www.flickr.com/photos/julienlooten/
Copyright: Julien Looten
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.

"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."

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

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.
