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)

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!

This capture was made in the Villarrica national park, 10 km from the city of Pucón, in the ninth region in the south of Chile, the actively erupting volcano named Villarica or in the native peoples Ruka Pillán, or house of the pillán (spirit ), is a stratovolcano of 2947 meters above sea level. high, adjacent to lakes Villarica and Calafquén, it is one of the most active in South America and has an almost perfect conical shape.

In the photograph we can see the incandescence of the Rukapillán volcano next to the Milky Way, the Southern Cross and the green airglow of the scene.

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.

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.

Processed in PI and PS.

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

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.

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



(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!

M51 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
