ImageM51 LRVB by David Duarte, sur Flickr

Internship photo.

For the end of Fleurine's course, I asked her to capture and process the galaxy M51, which is about 27 million light years away.

Here are 2 photos, 1 framed in a wide field and 1 framed in a close-up, which highlights its particular shape, reminiscent of a snail. I would have renamed it the "Snail Galaxy" rather than the "Whirlpool Galaxy".

Because of the weather conditions, we had to take the photos over 2 nights. So we were able to see the whole process involved in cropping and aligning all the shots over several nights.
Fleurine was able to control the entire observatory: opening the roof, controlling the mount, pointing the target, cooling the sensor, changing the filters manually and automatically according to a sequence.

For the exercise, we acquired 10 images of 5 minutes on the L filter and 10 images of 1 minute on the 3 RGB colour channels, giving us a total exposure time of 80 minutes, all processed in dedicated software also used by NASA, PIXINSIGHT.

L = 10x300S = 50 minutes
R = 10x60S = 10 minutes
G = 10x60S = 10 minutes
B = 10x60S = 10 minutes

Equipment :
Newton 200/1000 type telescope
AZEQ6GT PRO equatorial mount
Imaging camera ZWO 1600MM PRO
ZWO 120MC guiding camera

NGC 6914 region in Cygnus - Blue diamonds embedded in clouds of H-Alpha


Image
(Thumb only)

>>>High Resolution: https://astrophoto-hannover.de/download ... s_Horn.jpg

North of the star Sadr (γ Cygni) in the constellation Cygnus, at a distance of about 6,000 light-years, the reflection nebulae NGC 6914, VdB 131, and 132 are located, whose blue starlight is reflected by surrounding dust clouds. They are embedded in rich clouds of hydrogen, which are illuminated by young, hot stars, as well as some spectacular dark nebulae (including LDN 897, 899, and 900).
For processing, I had 5 hours of RGB data and 3 hours of H-alpha data available, captured with the 200/1000 Newton telescope, which was reduced to a focal length of 750mm at f/3.75 using the Starizona Nexus.
During processing, the challenge for me was to find the optimal color and brightness balance between the reflection nebulae and the H-alpha regions and to bring out as many details as possible (including in the dark nebulae) without losing the "fluffiness" of the gas clouds.
I hope you like it!

Time for some Fireworks!

Presenting my last galaxy shot of the season, NGC6946 or the Fireworks galaxy along with open cluster NGC 6939.
The Fireworks Galaxy
The Fireworks Galaxy
Title : A Galaxy and an open Star Cluster

This image was taken from Bortle 7.5 skies. In early May, when Cygnus was rising late, I decided to spend time on this target which I imaged 3 years back with some modest equipment. I spent about 9 hrs using LRGB filters from Astrodon. I imaged this with a Skywatcherusa Esprit 120ED and ZWOASI 294mm pro camera. Galaxy imaging from Bortle 7 is possible!

Open cluster NGC 6939 is approximately 5,000 light-years away in the constellation Cepheus. The small, faint, vertical galaxy in the top left is cataloged as PGC64824. There are several other galaxies in the frame which becomes visible once you remove the stars.

NGC 6946 is a spiral galaxy about 22 million light years from Earth located between the constellations Cepheus and Cygnus. lt's about 40000 light years across making it about a third the size of the Milky Way. NGC 6946 got the nickname "Fireworks Galaxy from its ten supernovas observed over the past century.

SH2-91 is part of the larger Cygnus Loop and a remnant of a supernova explosion that occurred around 10,000 to 20,000 years ago. It features intricate filaments and delicate structures that emit a striking glow, primarily in the Ha primarily wavelength, as well as OIII.

It took me just over 42 hours to capture Ha + OIII data of 600 sec subs, using the RedCat61 + ASI2600MM + Antlia 3nm Ha + Chroma 5nm OIII filters.

RCW114 - The Dragon's Heart.
111h of RCW114 - 4-Panel Mosaic with NB Stars


Located in the southern constellation Ara, RCW114 is a stunning supernova remnant that stretches out from the galactic plane. This ancient explosion has created a mesmerizing display of intricate waves and filaments, shaped by the shockwave colliding with interstellar gas. The delicate, undulating patterns in this image showcase the beauty and complexity of this cosmic phenomenon.

RCW114 is not commonly imaged, making it a unique target for astrophotographers. The remnant spans approximately 100 light-years across, making it a truly vast structure in the night sky. The lack of Oiii emission suggests that it was formed by a relatively weak supernova, adding to its enigmatic nature.

Thanks for checking.

This picture was taken in Saint-May, Drôme Provençale, France, more precisely in the Parc Naturel Régional des Baronnies Provençales, wich is currently under the process to become a RICE ( International Dark Sky Reserve with IDA Dark Sky Association)

My picture can be credited if shared with this instagram account : Instagram.com/martinlefrancphotographie

Here is more about the picture :

The nocturnal magic of Saint-May, in the Drôme

This is nother image made as part of my night tour of the Baronnies Provençales. Again I was granted with some amazing airglow, there is more and more of this green airglow visible in this region, and sometimes in fascinating manners like here where it was arching across all southern horizon. Maybe this is due to the fact that more and more villages like Saint-May are turning their lights off at night.

This is a panorama covering 180°, which gives this "3D" aspect, a little distorted of the foreground. But it allows you to admire the celestial vault in a wide field!

It was taken in the heart of the picturesque village, with its narrow streets typical of the perched villages of the Drôme Provençale. The village lies between a steep rocky outcrop and the Caire rock above Remuzat. It overlooks the Eygues valley. Minimum altitude: 382m. Maximum altitude: 1173m! In the background, you can admire the Saint-Laurent plateau, majestic under a starry sky.

In the sky, the arch of the Milky Way stretches magnificently over the village, illuminating the landscape with its celestial glow.

There's also an impressive airglow, those subtle natural light waves created by chemical reactions in the upper atmosphere, adding a touch of mystery and beauty to the scene.

In St May, street lighting is turned off in the evening, allowing the stars to shine in all their splendor and offering an incomparable night sky-watching experience. The low population density of the surrounding area, and the policy of switching off street lighting throughout the Baronnies Natural Regional Park, makes for one of the best night-time experiences in France!

Saint Peter's and the Moon
by Emanuele Colonnelli, on Flickr

I've been contemplating submitting this photo to APOD for a while. Honestly, I feel a bit nervous about being judged after struggling so much to achieve this result, but I think you might find the story behind it interesting and appreciate how I made it. I'll do my best to keep it simple and short. 😄

For almost two years, I've been trying to capture the moon fading behind St. Peter's dome in Rome. Initially, I failed due to poor night photography skills, so I studied hard, practiced a lot, and invested my savings in better tools. Even then, it wasn't enough! Luck plays a considerable part in night photography. I meticulously planned this shot five times between 2023 and 2024, and every time I had the conditions I wanted (blue hour, full moon, clear sky), it started to rain. I began to think there was a spell preventing me from capturing it! 😊

Last week, on June 17th, 2024, at almost 2 a.m. CET, I knew there was another alignment. I calculated it in advance, but I almost gave up since the moon wasn't as full as I wanted and the sky was too dark. In my dreams, I wanted to take this photo as "pure photography," meaning no HDR and minimal post-production. To achieve this, I needed the blue hour, but it's okay—some work in Photoshop won't kill me.

So, it happened. I captured a clear photo of the moon fading behind Saint Peter's, which is pretty meaningful for a native Roman like me.

A few words about the process:

The photo of the perfect alignment was taken at 2:06 a.m. on June 17th, 2024.
Shooting location: 41.90885120287977, 12.480983029723275
Camera: Olympus OM-1 mk1, ISO: 400
Lens: M.Zuiko 100-400 at 400mm, f/6.3
Tripod + remote shutter

I took several pictures of the moon every 10 seconds and selected only three of them. Moon exposure was 1 second at ISO 400. After the moon set, I kept the tripod in the same position to take a long exposure photo of the landscape, otherwise, I would have only captured the silhouette. In the end, I merged everything in Photoshop and did some tone mapping to harmonize it all.

If you want, you can verify the EXIF information in the JPEG file, even if some information is not 100% correct since it's the result of a time-blend in Photoshop. I know I'm paranoid, but I take honesty seriously. :-)

Cosmic Horror, LBN 406
Copyright: Pawel Radomski
LBN406_LRGB_v4_1920px_s.jpg
I am thrilled to share with you my latest astrophotographic achievement: capturing the enigmatic LBN 406. This stunning object, located in the constellation of Draco, is often overlooked by astrophotographers due to its faintness and the challenges associated with imaging it at a high resolution. However, I believe I am one of the few who have managed to photograph this cosmic marvel at such a small scale, achieving high magnification and revealing intricate details seldom seen in other images. To be honest, I have not found any photo of this object at such a scale.

Clear skies and happy imaging!

My name is Fabio Carbonara, I live in Torino (Turin), first capital of Italy and photography is one of my passion since 1976 …
“Meeting at the beginning of summer”.
The sun is rising exactly behind the Basilica of Superga, probably the most famous church at the top of hills eastern of the city.
The scene was captured on June 22nd at 0554:23 hrs from a small village called San Dalmazzo in the surroundings of Torino.
The distance from the Basilica is about 21 Km. Shot with 1200mm of focal length (600+teleconverter 2x), ISO 64, 176400s, f.45. The extremely closed aperture gives such a contrast that also solar spots can be noticed. Sun borders are not so sharp due to some humidity in the air.
I welcome any sharing and forwarding you might consider, if deserved.
Thank you very much for your attention.

Hello

Here is my submission : NGC1365

NGC 1365 is a striking barred spiral galaxy located approximately 56 million light-years away in the constellation Fornax.
Known as the Great Barred Spiral Galaxy, NGC 1365 spans about 200,000 light-years and exhibits a prominent central bar and well-defined spiral arms.
This bar plays a crucial role in transporting gas and dust toward the center, fueling star formation and the activity of the central part.
Its core then contains a supermassive black hole that represents 2 million solar masses. It rotates at close to the speed of light. These observations, announced in February 2013, were made using the X-ray telescope satellite NuSTAR
The central bar of NGC 1365 completes a full rotation in just a few hundred million years, which is pretty fast for structures of this size. This rotation contributes to the internal dynamics and the distribution of material within the galaxy.
 Data were acquired via Telescope Live, a CDK 24 telescope and  a QHY600M, with a total exposure time of around 8h45min  .

The aim of this processing was to preserve and reveal the intricate details of the galaxy’s structure, including its vibrant star-forming regions and dark dust lanes, without fallling into overprocessing or artifacts.
I also tried to take special care in processing the stars, focusing on their color, size, and halo.

I hope you will like it  !

I couldn't be happier with this one, I think it's my best photo yet.

I usually take it slow with astrophotography, but this time I took it extra slow. I spent over 50 hours collecting data on this nebula, and then I threw the majority of that away, to keep only the highest quality frames.

I give you the Statue of Liberty Nebula (NGC 3576) in the Hubble colour palette (SHO).

HDR corona with TEC140
The HDR corona from the TEC140+ASI6200MM setup. A great quantity of fine details is visible all along the corona. Prominences were added from C2 and C3 contacts, red coloured. Moon edge is clearly oval due to the long duration of this eclipse (more than 4 min), and during the image acquisition the Moon moved. This is the biggest setup of our eclipse expedition and it was extremely difficult to take this setup from Italy. The telescope has beed dismounted in 3 pieces, and two big suitcases were necessary for transportation via airplane. The camera is a ASI6200MM, a full frame of 61 Mpix 16 bit monochrome, and it was a first time for us uf using an astronomical camera instead of a reflex camera. This was possible thanks to the big improvement in download speeds of modern camera, e.g. this big frame sensor is downloaded to PC in less than half a second!

TEC140 apochromatic refractor (dia 140 mm, FL 1011 mm, f/7.2), ASI 6200 MM camera (CMOS full frame 62 Mpix, 16 bit monochromatic, binning 1, 3.76 um/pixel, cooling at 0°C), ZWO AM5 mount, Luminance filter, exposures between 1 ms and 512 ms at 1 EV stops at gain 100 (equivalent to 680 ISO, EV stops from 15.9 to 3.9), 381 frames used summing for a total of 52.2 s of net exposure captured during 187 s of gross duration. Image capture via an automated sequence in SharpCap recording data at 2 fps with a data flux of 242 MB/s into a SER file.
