The Center of the Milky Way and its surroundings.

Four days of gathering material, 12 heavily overlapping panels, 475 exposures of 120 seconds each, and the stunning southern sky over South Africa.

My focus was not on saturating the H-alpha regions but rather on showcasing the "interplay of planes and dust layers" overlapping each other in the Milky Way image. I wanted to highlight how the dust streams of the Great Rift influence the Rho and Zeta Ophiuchi areas, as well as many other larger and smaller details that often do not play the primary role. Did I succeed?

This is a superb image! I would love to see it as an APOD!

It's not often imaged by itself, Thor's Hammer in IC1848 in the HST palette. Done with the 16in Dall-Kirkham and Player One Poseidon mono camera, imaged remotely from Spain. It's the third image from it and so far I am really loving the way its running. Exposure time were 60x 180s Ha and 75x 300s each in O3 and S2 total 13hrs.
Thanks for looking

Meteor and Aurora display over Brasstown Bald

On the night of August 12, the Perseid meteor shower coincided with a strong geomagnetic storm, making the northern lights visible as far south as Georgia. The vibrant auroras began to emerge in the northern sky just after 1 AM. Simultaneously, an intense shower of meteors, originating from the constellation Perseus in the northeastern sky, lit up the night as Earth passed through the comet Swift-Tuttle's debris. In this image, small streaks of meteors can be seen as they burned up in Earth's atmosphere.

A Blue Moon from the Czech Republic

I used a Newtonian telescope and a ZWO ASI 294MC to capture this. It happened on 19 08 2024. It essentially was a test of a new workflow for very fast moving objects and a low amount of quickly captured frames.

Suggested Title: Eternal Slumber: Elephant Remains Under the Starry Sky of the Okavango

Image Credit & Copyright: Amaar Amir @_amaar_amir

Explanation: What may first appear as the remnants of some colossal otherworldly being, is in reality the weathered bones of a mighty bull elephant who once roamed the open planes of the Okavango. Declared a UNESCO World Heritage Site in 2014, the Okavango Delta in northwestern Botswana stands as one of the largest endorheic river systems on Earth. The waters of the Okavango drain into the vast expanse of the Kalahari Desert, creating a unique and thriving oasis amid the surrounding arid landscapes. As a result, Botswana is home to a remarkable array of flora and fauna, including the largest herds of African Elephants in the world. Elephants are remarkably intelligent creatures and exhibit highly complex social interactions. Studies have documented mourning and grief-like behaviors in the form of caressing the remains of a deceased individual with their trunks, remaining in close proximity to the body, vocalizing low-frequency rumbles, and sometimes revisiting the site of death months or even years later. This photo records the setting core of the Milky Way galaxy behind the relatively untouched skeleton of a 60-year-old bull who passed away naturally. The tusks were removed by wildlife authorities to protect against disruption by poachers. The remaining bones will gradually disappear as other herbivores chew and consume the bone fragments, a behavior known as osteophagia, to extract essential nutrients including calcium and phosphorus.

Details regarding data acquisition: This image was taken in the field deep in the bush of the Okovango, as we set out from "Mma Dinare" Camp. The foreground was a single image and the sky was a stack of 18 individual images to help with noise reduction, color, and detail enhancement of the central band of the Milky Way galaxy. Imaging at night in the unfenced private concession was truly a unique experience due to the abundant mosquitos and presence of active predators. Upon the recommendation of our guide, we had to suffice with the amount of images already taken as he was growing uncomfortable due to the sound of advancing hyenas and a nearby herds of buffalos!

Images / compositions of today's Saturn occultation. The difference in brightness between the two objects has made capturing and processing difficult... But I think it has been worth it... Good seeing conditions have helped to take some decent images. I hope you like the images

The equipment used was an 11" Celestron Schmidt Cassegrain telescope with a planetary dedicated camera, and a 2x Barlow, with other small optical and mechanical accessories, like a Focuser or UV-IR cut filter...
The image was processed in Autostakkert, Astrosurface and the composition was made in Photoshop.

Abell 36 - Pk 318+41.1 +50 Hs NB in HOO palette

Abell 36 is a fascinating planetary nebula located in the constellation of Virgo. This nebula is a result of a dying sun-like star shedding its outer layers, creating a beautiful and complex structure in space. This report provides a detailed description of Abell 36, synthesizing information from various sources to offer a comprehensive understanding of this celestial object.

Location and Discovery
Abell 36 is situated approximately 780 to 800 light years away from Earth in the constellation of Virgo. It was discovered in the 1950s by the American astronomer George Ogden Abell, which is why it bears his name.

Structure and Appearance
The nebula is faint and barrel-shaped, with a very faint halo of ionized gas that measures about 4° x 5° in angular diameter. The inner part of the nebula has a resemblance to the helical-shaped Cat's Eye Nebula (NGC 6543) with two pairs of bipolar lobes. This bipolar structure is a common feature in many planetary nebulae.

Central Star and Temperature
At the heart of Abell 36 lies a very hot white dwarf star, known as FB138, with an effective surface temperature exceeding 73,000 K. This central star emits a significant amount of ultraviolet radiation, which ionizes the surrounding gas and causes it to glow.

Formation and Age
The nebula is estimated to have formed around 10,000 years ago. This formation is a result of the central star expelling its outer layers as it runs out of nuclear fuel, a common end stage for low-mass stars like our Sun.

Future and Significance
Over the next 10,000 years, the nebula will continue to expand and dissipate into the interstellar medium, eventually becoming invisible. This process is a glimpse into the future of our own Sun, which will undergo a similar transformation in billions of years.

Abell 36 is a remarkable example of a planetary nebula, showcasing the final stages of stellar evolution for sun-like stars. Its complex structure, hot central star, and faint halo make it a subject of interest for astronomers and astrophotographers alike. Understanding Abell 36 not only provides insights into the life cycle of stars but also offers a preview of the eventual fate of our own solar system.

vdB141 The Ghost Nebula

The Ghost Nebula (designated Sh2-136, VdB 141) is a reflection nebula located in the constellation Cepheus. Looking at the adjacent image, the nebula's name is easily understood. This nebula spans about 2 light years across and lies about 1500 light years away.

The star right in the middle of the nebula is a proto-star and there are several stars embedded, whose reflected light make the nebula appear a yellowish-brown color.

The Ghost Nebula is in Cepheus Constellation and is plenty around a large number of hot stars. Part of the Cepheus Flare at the edge of the Milky Way's plane, the Ghost is about two light years across and exhibits clear signs of star formation.

Perseid Meteor and the Milky Way

The night before the Perseid Meteor Shower was set to peak on August 11, I spent the evening at Wayah Bald. The fire tower is located at high altitude in Nantahala National forest.
During the day it’s quite popular because this is where Appalachian Trail and Bartram Trail intersect. And at night, it offers a secluded setting for stargazing, away from city light pollution. Although Franklin is nearby, the southeastern sky is free from city lights.

Meteors rained through the sky all night. There was this one meteor that made a spectacular entrance as it passed just close to the galactic center. And in that moment, I clicked.

It was the brightest meteor I saw that night. As for the rest for the night, mists engulfed the forest but I just sat there near the tower and watched the meteor fall from the sky one after another.

Multiple exposure image. The stars and milky way are 20 exposures stacked to reduce noise. Single exposure for the meteor and foreground.
