The Lion Nebula
Sh2-132 is an interesting nebula, part of the Sharpless catalog, primarily a star formation area with several massive hot blue stars ionizing the gasses in this formation .
There are also two Wolf-Rayet stars identified within the nebula, these are supermassive highly energetic stars with very powerful stellar wind.
The Lion Nebula is about 10,000 light years distant, and is a faint object compared to many nebulae requiring some long exposures to bring out the detail.
I shot this image a few days ago in Vermont on a rare clear night.
This is an SHO image using 3nm ( very narrow ) filters for Sulphur (red), Hydrogen ( green) and Oxygen ( blue) so this gives us some idea of what's going on in this nebula.
Do you think it looks like a Lion ?

Hello!

This is Milky Way (and M31), captured in France, Aveyron, on the 11th August, 2023.
Very nice weather and a beautiful sky at night, even if some gradient remains at the bottom left and right.

I do astrophot since one year by now, and I recently discover starless background to work with. Hope you will enjoy this pic!

Technical stuff :

- Total of 480sec stacking, with 15 sec. each picture, taken at iso 4000
- Nikon D610 with 17-35mm Nikkor F1:2.8 ED (17mm at 2.8 aperture here)
- Using Siril to stack an adjust
- Using StarNet to work with starless background
- Gimp to reassemble both starless and original stacked result, adjusting opacity and some other parameter

My Comet Chaser

We spent the night waiting to see the comet C 2023 P1 Nishimura. Having some fun lookin Orion for the first time after spring and summer.
The comet rises from the horizon just before the sunrise so I take this picture. For the comet it's a stacking of 120 images at 550mm took with my Nikon Z6IIa on a Tamron 150-600mm G2. All the gear mounted on astrotracker. Obviously the comet and the girl were in the real position.
Hope you lke! It was very amazing for us.

Little Dumbbell Nebula

Approximately 2500 light-years from our planet, a dying star disperses a shell of gas around itself, creating a nebula with a distinctive double-lobe structure.

M76 is one of the few planetary nebulae listed in the Messier catalog and is located in the Perseus constellation. Its modest apparent size and not very high magnitude, although concentrated, do not make it a particularly bright and easy-to-observe cosmic object.

Also known by various imaginative names, from Cork Nebula to Barbell Nebula, the Little Dumbbell Nebula does not exceed 3 arcminutes in its brightest central part, while traces of the older and more diffuse outer zones can still be captured through astrophotography.

In fact, it's easy to see much more than what you notice in this photograph. This image was created over three nights, one for H-Alpha emission, one for oxygen (OIII), and a third for R, G, and B captures. Therefore, the result can be easily improved from here, with the same sky and equipment, by simply integrating more data and adding many hours of luminance, which are completely missing here.

It was supposed to be just a "first round" for the new setup equipped with Player One instruments, especially testing the newly installed motorized wheel. However, from a simple test, I became passionate about the amount of information I was obtaining about this small cosmic object.

I want to return to photograph it soon, perhaps by adding to this initial result. In fact, this is an object that will be moderately higher in the night sky in about a month or so, so there will be plenty of opportunities to integrate data already this year.

Location of capture: Breda, Spain
Date of capture: different nights between September 7 and 11

Hello everyone, I send my submission to APOD!
A cosmic bubble, NGC7635 The Bubble Nebula, it is a H II region emission nebula located in the constellation Cassiopeia. Stars are born inside these nebulae. Ultraviolet radiation emitted by stars inside and outside the nebula ionizes the gas and causes it to glow and emit its own light.
The "bubble" of gas from which this nebula takes its name has been formed by stellar winds, traveling at about 2000 km/s, from a central star, which has between 10 and 20 times the mass of our sun, they have been deforming and expanding the gas.
This nebula is at a distance of between 7,100 and 11,000 light years from Earth. The diameter of the bubble is said to be about 7 light years.
Image taken during these last nights. 14.25 hours of integration with photographs of 5 minutes of exposure each (171 photographs of 5 minutes of exposure in total)

Set up: Celestron C11 XLT, Skywatcher AzEq6 Mount, PlayerOne Ares C PRO, OAG celestron, ZWO asi 120mc-s, Obtolong L-Enhance dual band filter.

Software ( for capture and processing): NINA, PHD2 guiding, SiriL, Pixinsight)

Movement of the Airglow in front of the milky way, White Desert (time laps )

An atmospheric emission of light known as airglow, also known as nightglow, occurs on planets. Even if the impacts of starlight and diffused sunlight from the far side are eliminated, the night sky on Earth never truly darkens due to this optical phenomenon.

Comet C/2023 P1 (Nishimura)
Between the Trees in the Black Desert, Comet Nishimura

Deep in the Black Desert, one of Egypt's natural reservesوWithin this area there are many perennial trees.

As soon as I heard about the appearance of this beautiful green comet, I rushed to take a picture of it from this place. It is a comet whose period exceeds 400 years, and therefore the current population of the world will not see it again.

I woke up an hour before sunrise and prepared to take a photo of him that I will always remember

Story:
A incredible night in Rainbow Valley, Atacama Desert in Chile.
The Rainbow Valley, located in the Atacama Desert near San Pedro de Atacama, is one of Chile's most stunning natural wonders. Its name is derived from the array of colors that paint its mountains and valleys, a tapestry of hues caused by mineralization over millennia. The colors range from gold and red to green and blue, creating an almost surreal landscape under the intense desert sun. Beyond its rich and diverse color palette, the valley is dotted with peculiar rock formations and canyons carved by erosion. Visiting the Rainbow Valley is a journey through geological time, offering visitors a chance to marvel at nature's strength and Earth's ability to craft beauty in the harshest of conditions.

ISS2.jpg
International space station

The most important thing to know about this photo, is that the camera used to capture is not a regular planetary sensor or even a DSLR. Rather, it is the camera of a mid-range mobile phone!
This method is called "Afocal photography"

This pass was very unique for my location. Due to the maximum altitude of 90°, Which makes the distance between the station and the observer the least possible value.

To capture this image, I attached the mobile phone to the telescope's eyepiece. Then I tried to focus with a bright star and set the right exposure time and ISO for the video frames. After a few minutes, ISS rised up. I started to manually track it. Fortunately, when it's altitude was between 80° and 90°, I could keep it in the screen for about 2 seconds. That 2 seconds was the best part of my 3 minute video.

The next step was processing. I used pipp to get the frames wich included the ISS. Then I chose 100 frames for stacking. Out of those 100 frames, 15 of the best ones were stacked in autostakkert!3. And finally sharpened in registax6.

It is quite Interesting that 2 out of the 4 pairs of main solar arrays are not visible in this image. This is because they were not reflecting sunlight towards me.

SH2-132 Lion nebula

Located in the constellation of Cepheus, the Lion Nebula is situated approximately 10,400 light-years away from Earth. This nebula derives its name from its striking resemblance to a majestic lion, adorned with a remarkable mane. Within it, two distinct components are discernible: a region rich in hydrogen (HA) representing the head with the mane, as well as the body and tail of the nebula primarily appearing in the form of oxygen (OIII).

I've taken this image today at 12:36 (GMT +2:00) This is by far biggest sun prominance (or CME) that i got to shoot. Also sun today was going crazy with it's edge features with many other prominances and CME's, that's why i'm uploading dew more images. Image was taken at Grodzisk('s) Mazowiecki('s) Observatory entirely by me.

ISS and Soyuz docking (with timelapse video) - 23/09/15
Copyright: Alberto Vacca
Image URL: https://www.flickr.com/photos/197853132 ... ed-public/
ISS_23-09-15_image.png

Description:
The International Space Station was in good visibility conditions on 15th September 2023 from my city in Italy, when it was 68° above the horizon just some minutes before Soyuz MS-24, carrying a NASA astronaut and two cosmonauts, docked to the ISS. Here is the timelapse video of the passage:
Click to play embedded YouTube video.
The approaching Soyuz vehicle is pointed by the red arrow in the center of the video, that shows the central 3 minutes of the pass and has been sped up 10 times.
To track the ISS I used a software written by me that connects the telescope to PC, using the ASCOM platform, and sends the right commands to the mount to keep the satellite in the center of the image. The idea of this program was born almost a year ago from the desire to take shots like this one, in which the Space Station is observed as it approaches and changes angles: the idea has finally come true and soon I hope to be able to make the program available to amateur astronomers who want to try this kind of photography.

The video starting time is: 2023 September 15, 20:48 local time (18:48 UT).
Location: Parma (Emilia-Romagna, Italy), home garden.

Equipment:
- Celestron Nexstar 127slt maksutov telescope, on its alt-azimuth mount
- Zwo Asi 120mc-s color camera

Software:
- FireCapture (video recording)
- PIPP (debayer and aligning)
- Registax (image sharpening)
- Adobe Photoshop (rescaling of the image and final adjustments)

ImageFearless Night by Wael Omar, on Flickr
This image was full of adventure as it was very far away inside the desert by 2 hours drive from nearest city and 5 hours from home. I had to climb very steep cliff and to overcome my fears and set on this high spot over the mountain to have this view.
There were no one to help me to image the foreground with me inside the frame so I use intervalometer and walk for about 300 meters away from the camera in a very dark place ( Moon was crescent) then set in the planned spot for about 20 seconds with no move at all to avoid motion blur then get back to the camera to see how the image look like and if I am in frame or not . Too much pain and efforts but I was pleased when finally I succeed in get the image as I planned.

Story:
The Milky Way crosses the sky of Piedras Rojas while the Zodiacal Light and Air Glow complement the night sky spectacle of the Atacama Desert in Chile.
Situated in the Atacama Desert, the Piedras Rojas is specifically located near the Argentinian border, approximately 150 kilometers southeast of the town of San Pedro de Atacama. As the name suggests, the most prominent feature of this area is the reddish rocks and formations. Adjacent to the red rock formations are a few altiplanic lagoons. The high salt concentration of these lagoons gives the water a reflective quality, providing visitors with breathtaking views of the surrounding.
Dominating the upper third of the frame is the dense, cloudy stretch of the Milky Way. This band, filled with millions of stars, clusters, and interstellar dust, offers a rich tonal gradient, transitioning from a brighter core to fainter edges. The central bulge, with a higher concentration of stars, appears more pronounced and is the visual anchor of the Milky Way in this image.
Radiating from the horizon and stretching towards the Milky Way's core is the Zodiacal Light. This is an elongated, faint, triangular glow, appearing opposite the setting or rising sun. It is a result of sunlight scattering off interplanetary dust particles that lie in the plane of the solar system. Its presence is indicative of the image being taken shortly after sunset or just before sunrise and serves to bridge the gap between the terrestrial and celestial components of the photo.
Providing a vivid color palette against the backdrop of space, the air glow appears as faint ripples of luminescence, manifesting in shades of red, green, and even purple. This phenomenon is caused by the recombination of atoms and molecules that were photoionized by the sun during the day, combined with chemiluminescence, where chemical reactions in the upper atmosphere produce light. Its patchy distribution lends an uneven, wavy texture to the night sky, juxtaposing the more uniform, granular spread of the Milky Way stars.
