NGC 5367 Reflection Nebula (LRGB) NGC 5367, also known as IC 4347, is a reflection nebula that reflects light from two bluish stars. #astrophotography #astronomy #photography #art #space #science #PhotographersUnite #BlueskyArtShow @kat-astro-bot.bsky.social (For more info click ALT 👇)

NGC 5367 Reflection Nebula (LRGB). Astrophoto by Beatrice Heinze (Processing) and Telescope Live (Data).

It is located in the Centaurus constellation (Southern Hemisphere) about 2,050 light-years away from Earth.

I did the stacking and processing in PixInsight.

It was the first time, I processed this nebula.

I think it's a stunning nebula. What's your opinion?

Telescope: ASA 500N, a 50-cm F3.8 corrected Newtonian telescope

Location: El Sauce Observatory, Rio Hurtado valley, Chile (Southern Hemisphere) => Bortle Class 1

Total exposure time: 4 hours

Clear Skies!

Just our Sun Getting ready for the August 12 eclipse, partial from my location. First light with my Quark Chromosphere (ultra-narrowband Ha). * Unfiltered Sony A7S + TS61EDPH * 120 images stacked Still some work to do on capture and processing, I’m completely new to this! #Astrophotography

False-colour H-alpha image of the full solar disc glowing orange against a black background. Fine chromospheric texture covers the surface, with dark filaments, sunspots, bright active regions and several prominences along the upper-left limb.

The pool was so still it looked like glass #BlueSkyArtShow #Glass #photography

A low-angle view across a perfectly still swimming pool at sunset. Dramatic clouds, palm trees and a lone walking figure are reflected in the water, while the tiled pool edge creates a strong diagonal toward the horizon.

Close-up of a glowing glass furnace in a Murano workshop. A long metal rod enters from the left, holding a dark, molten gather of glass against the brilliant white-orange opening, surrounded by scorched industrial machinery.

Shattered light, scattered across the ground. #BlueSkyArtShow #Glass #photography

Sepia-toned close-up of broken glass shards scattered across gravel, dry leaves and twigs. Sunlight catches the sharp edges and reflective surfaces, while the background fades into a soft blur.

M8 Lagoon Nebula (HOO) Finally, I was able to finish the project I mentioned on June, 10th => bsky.app/profile/beat... What do you think of it? #astrophotography #astronomy #PhotographersUnite #BlueSkyArtShow #PhotographersOfBluesky @kat-astro-bot.bsky.social Clear Skies! (See more ALT 👇)

M8 Lagoon Nebula (HOO). Astrophoto by Beatrice Heinze (Processing) and Telescope Live (Data).

I used the following software:
Astro Pixel Processor (stacking); PixInsight (processing) and the final touches I did in Affinity Photo V3, for which I also used a few of James Ritson’s macros, such as Live Denoise (Chroma) and Bandpass Sharpening (Fine).

Data: Telescope Live
Processing: Beatrice Heinze

Telescope: Planewave CDK24 (24 Inch/61cm)

Location: El Sauce Observatory, Rio Hurtado valley, Chile (Southern Hemisphere) => Bortle Class 1

Total exposure time: 1 hour 12 minutes

Beatrice Heinze Photography@beatriceheinze.bsky.social · 2mo ago

My next project, M8 Lagoon Nebula in HOO (Hydrogen-alpha/Oxygen/Oxygen), looking good so far 😀👍. I did the stacking of the exposure frames in Astro Pixel Processor, and now I'm using PixInsight for the processing. Stay tuned! 😊

The half-risen sun glows orange above a dark tree line at the Marais d’Orx. A thin layer of mist hangs over copper-colored water as two birds fly low across the still surface.

Schlieren photograph of a small candle flame against a dark background. The image is mostly black and white, except for the orange flame. Bright, twisting ribbons rise above it, revealing the changing density and turbulent movement of the heated air.

Macro photograph of a small dark bee standing on the bright yellow centre of a white daisy. A second tiny insect rests on a petal to the left, while another dark, blurred insect is partly visible behind the flower. The scene is sharply detailed against a smooth green background.

A tiny world revealed after the rain. #BlueSkyArtShow #Macro #Photography #BlackAndWhite

Black-and-white macro photograph of a flower covered in tiny water droplets. The bloom is seen from the side, with textured, crinkled petals surrounding a dark central bud. The flower and its hairy stem are sharply detailed against a soft, almost black blurred background, making the droplets sparkle.

Black-and-white photo of a cow grazing in a field, seen from a low angle. Its back and lowered neck form a strong curve against the bright sky. Other cows and a farm building appear in the distance.

Cosmic Curves 🔭 M27, the Dumbbell Nebula, 📷 Newton 130/900 and Sony A7S. M27 glows as its white-dwarf core ionizes the star’s expanding outer layers. @kat-astro-bot.bsky.social what do you see ? #BlueSkyArtShow #Curve #astrophotography #photography #M27 #DumbbellNebula

A wide-field astrophotograph of Messier 27, the Dumbbell Nebula, surrounded by a dense field of stars against a nearly black sky. The nebula is positioned near the center of the frame and appears as a softly glowing, irregular oval with two broad opposing lobes. Its brightest inner region is pale blue, cyan, and milky white, with translucent layers of gas overlapping around the faint central star. Curved reddish-pink arcs form parts of the outer shell, especially along the upper-left and lower-right edges, creating a rounded, expanding structure around the cooler blue interior. Fainter blue-green gas extends beyond the bright core as a diffuse halo. Hundreds of stars of different brightness fill the background, from tiny sharp points to several larger white stars with subtle four-point flares. Many stars show slight red and cyan fringes, adding small touches of color throughout the otherwise dark field. Captured with a Newton 130/900 telescope and a Sony A7S camera.

Today's #BlueskyArtShow theme is #curves. I've posted images from here before. It is an oak hammock in the Apalachicola National Forest that periodically floods with heavy rainfall. When it does we wade and make images. #photography #landscape #ECK #rain #oaktrees #forest #longexposure #reflections

Busy #Busy #BlueSkyArtShow #Photography #ECK #ClasdicMono #BlackAndWhitePhotography #StreetPhotography

A high-contrast, black and white photograph captured from a wide angle, looking down a long, steeply inclined, cylindrical tunnel packed with a large crowd of people. The crowd is seen from behind, moving away from the camera and descending deeper into the tunnel. The tunnel's structure is defined by a series of prominent, concentric arches that create a strong sense of depth and perspective, drawing the eye toward a distant, crowded exit. A continuous line of bright, rectangular overhead fluorescent lights runs along the ceiling, casting sharp illumination and creating deep shadows throughout the scene. The mood is dense and urban, emphasizing the scale of the crowd within the architectural space.
