Starship Asterisk*

[b]M81, Bode’s Galaxy. [/b]

It took the light from this galaxy 12 million years to reach us, and I welcomed it with an open telescope. I gave it a full day — 24 hours — of exposure over three nights in March (15th, 16th, and 17th.

For this feat, I employed the Edge HD 8, 0.7x Reducer, ASI533MC Pro, Antlia Quadband Filter, ZWO AM5, and dedicated a total of 23.7 Hours. All this, in the challenging Bortle 9 conditions of Vancouver, Canada.

Last fall I captured several tens of hours of images of the Triangulum galaxy, Messier 33. I used the popular broadband approach (LRGB), but also gathered more than 100 hours in narrow band filters in order to see the star forming regions and rich nebulae in this neighbouring galaxy. The image also showed some [b]IFN around M33[/b] (you can also see the starless version in my website that highlights this IFN).

The resulting image has more than 150 hours of exposure captured from my backyard observatory, located in the village of Prades, a Bortle 4 dark sky in the south of Barcelona (Spain).

I highlighted a faint nebula detected in the [OIII] and Ha channels that has been finally published as a new discovery:

It was published as a Research Note of the American Astronomical Society.

I'm pleased to submit to you for your consideration my latest work on the Witch Head nebula, IC 2118. It's a 102h LRGBHa image captured from my backyard observatory that aims to show not only the popular reflection nebula but all the galactic cirrus (Ha data) surrounding the scene.

Thanks for all your work. Best wishes,

Full image details:[/b]

In the Eridanus constellation, and close to the Orion constellation, we find a very interesting and pretty faint reflection nebula, IC 2118. Also known as the Witch Head nebula, IC 2118 is believed to be made of gas, and dust and is about 50 light-years across. Located around 900 light-years away from Earth, the Witch Head Nebula is illuminated by Rigel, the bright blue supergiant star in the constellation Orion. The blue color of the Witch Head nebula contrasts beautifully with the dusty red clouds around the nebula, creating a striking visual spectacle. These red clouds are galactic cirrus, galactic filamentary structures that surround our galaxy.

This 102h 25' image was acquired from my backyard observatory during several winter nights this 2024. I used my dual Takahashi FSQ setup in order to get double the data. One telescope, the FSQ85, was focused solely on Ha data in order to capture the faint galactic cirrus. More than 50 hours were needed to show the final detail. I find interesting trying to push the limits of my own amateur astrophotography work with such deep exposures that allows me to show several interesting details. If you look carefully, in the bottom right of the image a galactic cirrus reveals the shape of a a bat, just below the "mouth" of the witch. We called it pareidolia, but it's also a nice view of the deep universe. The other telescope, FSQ106, was used to capture the Luminance data along with the RGB.

Image details:

FSQ106:
L: 486 x 300" (40h 30')
RGB: (35,28,50 x 300") (9h 25')

Date - september 15 2023


Explnation -The aurora, also known as the Northern Lights in the Northern Hemisphere and the Southern Lights in the Southern Hemisphere, can appear in a variety of shapes and forms. Here are some of the common shapes of auroras:

Curtains: This is one of the most common shapes of auroras. Curtains appear as long, vertical bands of light that dance and sway across the sky. They often have a rippled or wavy appearance.
Arcs: Arcs are large, sweeping bands of light that stretch across the horizon. They can be either stationary or slowly move across the sky.
Rays: Auroral rays are narrow beams of light that shoot upwards from the horizon, resembling columns or pillars of light. They can extend from the horizon to high in the sky.
Coronas: As previously mentioned, corona-like auroras resemble the corona of the Sun. They appear as diffuse, circular shapes that spread out across the sky, sometimes surrounding a darker area near the zenith.
Bands: Bands are broad, flat regions of diffuse auroral light that cover a large portion of the sky. They often have a faint glow and lack the distinct structure seen in curtains or arcs.
Patches: Auroral patches are irregularly shaped areas of light that appear scattered across the sky. They can vary in size and brightness and often lack well-defined borders.
Discrete features: These include various shapes such as spirals, swirls, and loops that form within the aurora. These features can be more intricate and dynamic, often changing rapidly over short periods of time.

For your consideration: my longest project to date. With just over 42 hours, IC 2944 - The Running Chicken Nebula, was quite a challenge to image with such a little scope. IC 2944, famously known as the Running Chicken Nebula, lights up the southern skies in the constellation of Centaurus. This active stellar nursery, not just a visual spectacle but also a site of complex cosmic phenomena, is easily identifiable by its unique avian shape, which has captured the imagination of astronomers and stargazers alike.

In my Astrobin post above, you can find more details information about several parts of the image. What I like about it is that it highlight many interesting areas, such as:


Center of IC 2948 (Thackeray's Globules): This detailed crop of IC 2948 reveals the mysterious Thackeray's Globules - small, dense molecular clouds that appear as dark silhouettes against the brighter nebular glow. These globules are key sites for studying the early stages of star formation, providing clues about the life cycle of stars and the conditions within bustling nebular environments.

Below λ Centauri (Favorite Section): My favorite part of the nebula lies just below λ Centauri, where a nebulous formation presents itself with a mesmerizing blend of colors and shapes. This area, rich in ionized gases and scattered starlight, offers a breathtaking view that highlights the artistic beauty inherent in the cosmos.

Comet 12P/ Pons Brooks - a southern view

We have been seeing all the lovely images of Comet 12P/ Pons Brooks from the Northern Hemisphere and waiting to see it as it moves south. In the last couple of days the comet has been well enough placed for us to image it in detail. In the image the blue-grey ion tail is streaming away towards the upper right of the image, driven by the solar wind. There is tremendous structure to be seen here, with the thin streamers near the comet's head which then start to ripple, due to the varying strength of the solar wind, as they move away from the nucleus. The nucleus itself can be made out as the small bright object at the head of the comet. Off gases glow green to the left of the nucleus, where diatomic carbon is excited by UV light from the Sun and emits in the green spectrum. It has a short lifespan and does not persist much away from the nucleus. Meanwhile, the brown curved dust tail can be seen below and right. This is where debris has sloughed off the comet and lies along its curved trajectory. I believe we are seeing the dust tail, from in front at a narrow angle, which gives it a broad appearance. That tail is long but we are looking along its length.

From an orbital simulation one can see it had just rounded the Sun and is heading in our direction. The solar wind, from the Sun, at left, is causing the ion tail to stream away to the right.

The f/1.9 imaging is very fast and the 14” mirror means that a lot of photons can be gathered in a short time, thus the short exposures which freeze the comet’s movement. Classic comet processing techniques were used, whereby the stars were separated from the comet in each image, and a comet align tool was then used to align the comet images before integration. Finally the comet was then recombined with the stars.

The capture details are as follows:

Galaxy season ✅
Galaxy Cluster ✅
Bortle 7 😰 ✅
😶‍🌫️✅

The galaxy season is well and truly here. Presenting the famous M81 and M82 pair commonly known as the Bodes and Cigar galaxy! These galaxies are 12 Million light years away from us. It means that when we are looking at them, we are actually looking 12 Million years into the past because that's how long the light took to reach us!

M81, a spiral galaxy, whispers tales of graceful arms adorned with glittering star clusters, while M82, a tumultuous starburst galaxy, roars with the fiery birth of new celestial bodies amidst chaotic gas clouds. In their celestial ballet, we witness the relentless dance of creation and destruction, a reminder that the cosmos is both birthplace and a graveyard. Yet, amid the chaos, there is harmony—the delicate balance of forces sculpting the fabric of space-time.

It's possible to compare the apparent size of the Moon and the inner planets by capturing their silhouettes during solar eclipses and transits of Venus and Mercury.
The past years I was able to observe and capture all of these events. As I was using different cameras and lens, I re-scaled the photos.

NGC 3572, also known as the Pincushion Cluster, is a beautiful emission nebula and star cluster located in the constellation Carina. It’s often overlooked by astroimagers in favor of its brighter neighbor, the nearby Carina Nebula. The region contains approximately 150 young stars, including seven red giants and seven white dwarfs. The visible interstellar gas and dust are part of the star cluster’s natal molecular cloud. Dense streamers of material within the nebula, eroded by stellar winds and radiation, trail away from the energetic young stars, resembling cosmic tadpoles.

Hi everyone, this is my first post on this forum, I hope it's posted correctly
This is a composition in which the details of the solar ejections can be seen at their best

I took these images from Arkansas on April 8, and I was amazed that these ejections could be seen even when looking at the sun with glasses.

(Thumb only)

>>>High Resolution: https://astrophoto-hannover.de/downloads/Regulus_Dwarf_by_Markus_Horn.jpg

One of the brightest stars in the night sky and a dwarf galaxy right next to it: Regulus and the dwarf galaxy Leo I are a fascinating pair that I've had on my to-do list for quite some time.
Leo I is a dwarf spheroidal galaxy in the constellation Leo. At about 820,000 light-years distant, it is a member of the Local Group of galaxies and is thought to be one of the most distant satellites of the Milky Way galaxy.
Leo I is located only 12 arc minutes from Regulus, the brightest star in the constellation. For that reason, the galaxy is sometimes called the „Regulus Dwarf“. Scattered light from the star makes studying the galaxy more difficult.

[size=150]NGC 2403[/size]

This spiral galaxy in Camelopardalis is often compared to M33, but is imaged much less often. Visually, it is a bright binocular object. It is strikingly populated by H II regions, one of which is so large it has its own catalog designation [url=https://en.wikipedia.org/wiki/NGC_2404](NGC 2404)[/url] inside its parent galaxy. NGC 2403 is a mere 10 million light years away, a member of the M81 group, which is a close neighbor to our own Local Group.

Galactic Core Beyond the Hole in the Wall

I have wanted to travel to this bortle 1 location for this unique structure for over 2 year now and finally I had the chance to shoot the hole in the wall structure or "Makhroum El Sahraway" in the depth of the New Valley Desert 500 km away from Cairo due south. I shot the Milkyway sky first from the other side of the opening and shot the foreground from this side just before sunrise. I knew with such integration time for the sky from a bortle 1 that I would be able to pull up much detail and color so I took my time to finalize this blended composite.
