Greetings,
I hope this message finds you well! Attached below is my image and supporting information for your kind consideration of a NASA APOD.
Suggested Title: Botanical Prison Under the Starry Skies of Botswana
Alternative Title: Milkyway Shining Through a Baobab Prison Tree in Botswana
Image Credit: Amaar Amir @_amaar_amir
Explanation: The Baobab Prison Tree, a remarkable natural monument near Kasane, Botswana, stands as a silent witness to history and resilience. This ancient tree, with its massive trunk and sprawling branches, once served as a place of confinement for local prisoners, its hollow interior providing both shelter and restraint. It has also been used in postal services and as a meeting area for government officials. Known as the "Tree of Life," baobab trees are a vital resource to the nearby Chobe River and its inhabitants. These trees are dispersed in the Chobe area, surrounded by breathtaking landscapes where the largest herds of elephants in the planet reaching 50,000 roam around. As the Milky Way stretches overhead, this baobab serves as a poignant reminder of the intertwining of nature and human stories in this vibrant region, where the beauty of the wilderness meets the echoes of the past.
Details regarding data acquisition: This image was captured at the famous baobab prison tree in Kasane, Botswana near the official police station. This composite image was taken in the same time and place in the following manner, the foreground image was taken from inside the baobab tree with the camera pointing upwards, the background image is a result of a stack of 15 individual 20 sec exposures.

Date: August 16 , 2024
Sky: Bortle class 4
Camera: Sony A7r3 (unmodified)

Beacon of Nantahala!
https://naikonpixels.com/
Copyright: Prashant Naik
Location: Wayah Bald, Franklin, North Carolina
Date: August-11, 2024. The night before Perseids Meteor Shower.
Fire-towers are such an amazing experience. Wayah Bald in Nantahala National forest sits in the middle of the forest at high altitude to detect wildfires. Under the night sky, with the moon and stars as a backdrop, I see this as the Beacon of Nantahala. As the stars shine above, the forests breathes below. But it is named after the red wolves that once roamed this lands. In Cherokee, 'Wa Ya' means 'wolf.'
Multiple exposure image. The stars and milky way are 20 exposures stacked to reduce noise. Shots of meteors are blended from different images keeping their position in the sky intact.

Field of dreams

Copyright: Danijel Bosnjak CATEGORY:
tracked, stacked, blended.
STORY:
I still had a few vacations days left, and my family was over at friends down on the Adriatic coast, so i decided to go on a solo photo safari and make the best of it. Krbavsko polje is a historical region located in Mountainous Croatia, in the eastern part of Lika. This is a typical scene for this region, where during the Summer months, farmers collect and process the hay. This cutting is usually timed to occur when the hay is at its peak nutrient level to provide the best quality for feeding animals. This area is sparsely populated compared to rest of the country so i was pretty much alone during the whole night. A beautiful Bortle 3 location, we are lucky to still have access to places like this. It was a gorgeous mid-summer night, with perfect weather, and absolute silence broken up only by sporadic sounds of nearby livestock in the distance. Truly a field of dreams. And i got to have it all to myself. The Cosmos never felt closer.

The Gamma Cygni Nebulae
The supergiant star Gamma Cygni lies at the center of the constellation Swan (Cygnus). Known by its proper name Sadr, the bright star is also at the center of this beautiful panorama, which features a complex of stars, dust clouds and bright nebulae along the plane of our Milky Way galaxy. The emission nebulae IC 1318 (Butterfly Nebula) and NGC 6888 (Crescent Nebula), the star cluster NGC 6910 and the reflection nebulae NGC 6914 are clearly visible in this wide-field image, which extends about 6° (12 full moons).
The photo is a collage of data taken over the years and from 3 different locations (Montefeltro, Emilia, Spain), for a total of almost 6h of exposure.
RGB: Canon EF 300 mm f/4 with Canon EOS 6D mod. 62x180s f/5 3200 ISO - from Montecopiolo Italy
Ha (1): Nikkor 180 mm f/2.8 with Atik 4000 LE. 12x600s f/4 Ha 7nm - from Casalgrande Italy
Ha (2): Samyang 135mm f/2 with ZWO ASI 2600MM. 25x120s f/2.8 Ha 3nm - remotely from Fregenal De la Sierra Spain.

Sh2-142 / NGC7380 Wizard Nebula
https://www.astrobin.com/vqn8v2/
Copyright: Paweł Radomski
I allow to use this photo in APOD consideration and in social media associated to APOD
NGC 7380, also referred to as the Wizard Nebula, is an active star-forming complex situated approximately 7,200 light-years away in the Perseus Arm of the Milky Way, within the constellation Cepheus. This H II region, spanning roughly 110 light-years, is a prime example of an emission nebula, where intense ultraviolet radiation from newly formed, massive O-type and B-type stars ionizes the surrounding hydrogen gas, causing it to emit light.
Central to the nebula is the open star cluster, also designated as NGC 7380, which is only a few million years old. The most prominent star in the cluster, HD 240794, is an O7V star with a high effective temperature and luminosity, driving strong stellar winds that shape the surrounding nebula. These winds, along with radiation pressure, are responsible for the dynamic structures observed in the nebula, including pillars, ridges, and cavities. The "wizard-like" morphology of NGC 7380 is a result of these complex interactions between the young, massive stars and the interstellar medium (ISM).
Spectroscopic studies reveal that the nebula's emission is dominated by hydrogen-alpha (Hα) lines, with significant contributions from doubly ionized oxygen (O III) and singly ionized sulfur (S II). These emissions are crucial for mapping the physical conditions within the nebula, including electron temperature, density, and chemical abundances. NGC 7380 provides a valuable laboratory for studying the feedback effects of massive stars on their natal environments and the processes governing the lifecycle of the ISM.
Key Astrophysical Parameters:
Distance: ~7,200 light-years
Apparent Size: ~25 arcminutes
Physical Size: ~110 light-years
Spectral Types of Central Stars: O7V, B-type stars
Dominant Emission Lines: Hα, [O III],
Age of Star Cluster: ~4-5 million years

Sh2-126 (2-Panel Mosaic)
by Ali Alobaidly, on Flickr
https://live.staticflickr.com/65535/539 ... 7785_o.jpg
Description:
Sh2-126, also known as the Ionized Hydrogen Region LBN 428, is a large and faint emission nebula located in the constellation Lacerta. I've seen some call it the Gecko Nebula, though to me it looks more like a swimming dolphin. This region was a challenge to process due to the richness of the stars and the multiple wavelengths that I needed to combine. While my monochrome camera was occupied over at Cepheus, I decided to have a go at this target with my 382mm refractor. Shortly after giving it the command to slew to Lacerta, I quickly realized that my FOV was not satisfactory and started planning a mosaic on the spot. Then there was another issue: after 12 hours of broadband data, I found that my Hydrogen Alpha signal was pretty weak in my One Shot Color dedicated astrophotography camera, so I found myself in the desert the next day, armed with a 3nm Dual-Band filter and another 6 hours of my life to burn away under the stars (No regrets).
Then came the challenge of continuum subtraction and merging the Hydrogen data after stacking and stitching all the frames—and that was where the fun began. Trying to figure out how to make all this data come together in a satisfying way was immensely fulfilling, and it made resisting the heat of the Kuwaiti desert for 3 nights absolutely worthwhile!
This is what I came up with, and I hope to continue this mosaic in the future, but for now, I have to step back to reality and spend some quality time with my family and dedicate some of my attention to my day job. At least until the next new moon!

Then there was another issue: after 12 hours of broadband data, I found that my Hydrogen Alpha signal was pretty weak in my One Shot Color dedicated astrophotography camera, so I found myself in the desert the next day, armed with a 3nm Dual-Band filter and another 6 hours of my life to burn away under the stars (No regrets).
Then came the challenge of continuum subtraction and merging the Hydrogen data after stacking and stitching all the frames—and that was where the fun began. Trying to figure out how to make all this data come together in a satisfying way was immensely fulfilling, and it made resisting the heat of the Kuwaiti desert for 3 nights absolutely worthwhile!
This is what I came up with, and I hope to continue this mosaic in the future, but for now, I have to step back to reality and spend some quality time with my family and dedicate some of my attention to my day job. At least until the next new moon!

M45, the daughters of Atlas & Pleione – with Barnard’s Merope Nebula IC 349.
[url=https://flic.kr/p/2q9hbYa][img]htt ... .jpg[/img]M45 Pleiades + IC349 with inserts by Martina McGovern, on Flickr[/url]
M45 is known as The Pleiades or The Seven sisters, it is a group of very hot young stars. The name might lead you to think there are only 7 stars but there are over 1,000 stars in the open cluster.
In classical Greek mythology the name Pleiades was used for the seven divine sisters, their father Atlas and mother Pleione are also stars in the cluster.
The stars are passing through gas and dust clouds (nebulae). The hot, Blue coloured stars illuminate the gas and dust which makes it glow blue – Reflection Nebulae.
The star cluster is approx. 445 lightyears from us in the constellation of Taurus.

It’s believed the stars formed within the last 100 million years – that means dinosaurs were around before the Pleiades!
I have known about The Pleiades for so, so many years but it wasn’t until I started imaging it that I realised there is a small Nebula near the star Merope, IC 349 (0.6 light years from it). This was discovered in 1890 by American astronomer Edward Emerson Barnard, hence its name Barnard’s Merope Nebula. I challenged myself to capture this small nebula…
I have added Hubble’s (HST) image of this nebula in some of my images to let you see what is really looks like.
Total integration time for this image is just over 8hrs.
Equipment details:
Askar FRA400 (400mm FL), HEQ5 PRO, guided, ZWO ASI2600MC Pro, the Optolong L-Pro filter ….
All controlled with an ASIair Plus.
Imaging details:
Mainly 120sec subs, captured over 2 nights during January this year.
Where captured:
From my garden in the UK, near Cambridge city (in a very small village), Bortle 4 (ish).
Processing software:
Stacked etc and processed in PixInsight.
Thanks for looking and wishing you all Clear skies.

Echoes of a Violent Past: The Cygnus Loop
Stretching across the night sky, the Cygnus Loop is a supernova remnant from a star that exploded 10,000 years ago. This vast region spans nearly 3° in the sky, encompassing famous nebulae like the Western Veil (NGC 6960), the Eastern Veil (NGC 6992, NGC 6995, and IC 1340), and Pickering’s Triangle. Each section of the loop reveals the intricate remains of the star’s violent death, now displayed as delicate filaments of ionized gas.
While I see the Alien movie character in the Eastern Veil, what do you see?
Equipment
• Telescope: William Optics RedCat 51 II
• Camera: ZWO Astrophotography ASI2600MM Pro
• Mount: Sky-Watcher NEQ6-Pro
• Processed in: HOO with RGB stars
• Total integration time: 18 hours 15 minutes
• Bortle 6 sky

Re: Submissions: 2024 September
Floating serenely in the vastness of the night sky, the Dolphin Head Nebula (Sh2-308) stretches its ethereal fins, its soft, bubble-like form resembling a cosmic dolphin gliding through the interstellar sea. This stunning structure is a Wolf-Rayet nebula, sculpted by the powerful stellar winds from Wolf-Rayet star EZ Canis Majoris (WR 6), which lies at its heart. The stellar winds from this dying star have blown a vast bubble of glowing gas, forming the magnificent Dolphin Head Nebula.
Below the Dolphin’s head, you can faintly spot PNG 234.9-09.7, a small planetary nebula that adds a subtle yet captivating feature to the image. This planetary nebula, while faint, stands out as a reminder of the remnants left behind by stars in their final stages, contrasting the Wolf-Rayet bubble above it. This was a real challenge to capture in a Bortle 6 sky.
This image reveals both the grandeur of Sh2-308 and the hidden treasures that lie within its vicinity.
Equipment used:
• Telescope: William Optics RedCat 51 II
• Camera: ZWO Astrophotography ASI2600MM Pro
• Mount: Sky-Watcher NEQ6-Pro
• Processed in: HOO with Narrowband stars

The Omega Effect at Sunset
Have you ever watched the sun melt into a lake or ocean? This is known as the "Omega effect", when the sun develops feet at the bottom like the Greek Symbol Omega.
You are actually seeing an inverted image of the sun due to refraction. This mirage usually occurs when the sun's rays shine through a warm dense layer of air over a large lake or ocean.
