Starship Asterisk*

"The Land Before Time"

I have been following and researching CometC/2023 A3 (Tsuchinshan–ATLAS) for several months now. I had a feeling there was going to be a good chance we could see it here in the Northern Hemisphere, And I knew just the spot I wanted to go to capture it. This is one of my favorite spots to go for night photography, Borrego Springs, California. An extremely talented artist, Ricardo Breceda has built these giant metal sculptures and they are scattered throughout the desert here. The dinosaurs are my favorite! I captured this Monday night Oct 14th. While the moon was still pretty bright it wasn't totally full so still got some pretty good detail along with the foreground being lit up nicely.

NGC 1491, also known as LBN 794 or SH2-206, is a bright emission-type nebula located approximately 9,800 light-years from Earth in the constellation Perseus. The nebula obtains its dark red coloring due to Many massive stars (such as BD+50 866) embedded in NGC 1491 produce lots of ultraviolet radiation energizing/ionizing the hydrogen gas that makes up the nebula.

Story:
The Atacama Desert is renowned for its exceptional conditions that make it a prime location for astrofotography. The region's high altitude, averaging around 2,400 meters, results in a thin and dry atmosphere with minimal light pollution. This combination creates remarkably clear and stable skies, offering astronomers and photographers an unparalleled view of celestial objects. The absence of urban development in the surrounding areas further contributes to the pristine conditions, making the Atacama Desert one of the world's premier sites for capturing the wonders of the night sky.
Moreover, the Atacama boasts an arid climate, receiving minimal precipitation throughout the year. This low moisture content in the atmosphere minimizes the presence of clouds, ensuring extended periods of clear skies for astronomical observations. The combination of high altitude, low light pollution, and arid climate collectively establishes the Atacama Desert as an extraordinary haven for astrofotographers seeking optimal conditions to capture the beauty of the cosmos.
In addition to its atmospheric advantages, the Atacama hosts cutting-edge observatories, such as the European Southern Observatory (ESO) facilities, which further underscores its significance in the field of astrophysics. These state-of-the-art observatories leverage the pristine sky conditions to conduct groundbreaking research and capture stunning images of the universe, solidifying the Atacama Desert's reputation as a celestial paradise for astrofotography enthusiasts.

The California Nebula
this is my " first light" image taken at Dark Sky New Mexico on my Takahashi FSQ106/A-P 1100 combo
The California Nebula (NGC 1499) is an emission nebula about 1000 Light years from Earth.
Its name comes from the fact that the central most often imaged portion looks (a bit) like the outline of the state of California.
So maybe I should call this image "the West coast Nebula" as it does extend a fair bit further as its brightness diminishes.
This is a two-pane mosaic to capture the full width, and actually it was quite a 'pain' to process as Pixinsight's Mosaic process introduced artifacts and I eventually separately processed both images all the way through and merged the jpegs in PS.
The nebula is principally "excited" by the nearby star super energetic star Xi Persei (Menkib) the bright star in the image.

Lobster Claw Nebula in SHO palette, it tooks me more than 22 hours to get it, and maybe the same time to process it :)


Within this cosmic tapestry, the Bubble Nebula reveals itself in an explosion of colors, while the celestial jewels, NGC 7538 and NGC 7510, twinkle in the background. The image captures the moment when the Lobster Claw appears poised to devour these celestial prey, creating a fascinating astral ballet where beauty and voracity converge in the infinite expanse of the universe.

The Llanquihue National Reserve is one of the oldest protected wild areas in the country, it was created in 1912 and is located in the Andes mountain range, in the province of Llanquihue, communes of Puerto Varas, Puerto Montt and Cochamó, in the Region . of Los Lagos. Geographically it is located west of the Reloncaví estuary, in the mountainous area it extends north of Lake Chapo.
It is part of the Temperate Rain Forests of the Southern Andes Biosphere Reserve.

We can appreciate the impact on the vegetation and its erosion, resulting from the eruption of the Calbuco volcano in 2015.

Got to revisit one my early targets this season.

"While not strictly a constellation, the Pleiades, comprise a striking open star cluster visible to the naked eye. They are located at the shoulder of Taurus the Bull and appear to the naked eye as a miniature dipper. On a clear, dark night, a person with good eyesight can easily see six stars, and with a little patience, seven and perhaps more. (The record is said to be 19.) The cluster takes on even greater beauty when viewed through binoculars." - The Mythology of the Night Sky

No, flights to the Moon are not yet offered on Black Friday, but who knows in the coming future... :wink:

From time to time, during our photo and video captures of celestial objects, an airplane or satellite comes between our telescope and the sky object.

In this case, an [b]Airbus 320-112[/b] with registration EC-NBD of the Volotea company, covering [b]flight V72487 from Lanzarote (Spain) to Bordeaux (France)[/b], was pictured while taking videos for the hi resolution moon picture shown above.

How can we know those flight details? By knowing the exact moment when our image/video was captured, we can look applications on the Internet that inform about the flights (flightradar) and satellites (heavensabove) that fly over us at a given moment and location.

In this case it is just for fun, but it shows us the importance of collecting and reviewing all the data from our images systematically, because you never know when you may have captured an astronomical event (a TLP, Transient Lunar Phenomena for example) and it would be needed.

Cassiopeia A, SNR G111.7-02.1, or Cas A for short, is a supernova remnant (SNR) in the constellation of Cassiopeia that lies at a distance of roughly 11.000 lightyears and spans 10 lightyears in diameter.
What makes this SNR so special is that it’s the leftover of the second most recent supernova, dating back to approximately 1681. This makes it a very interesting target for professional research as it holds valuable information about the different stages of a supernova as well as of the different processes going on in a supernova.
In fact Cas A is one of the best studied objects in the night sky, especially in the realm of SNR’s, which is due to its proximity and young age. It already has proved valuable in understanding nucleosynthesis processes, shock physics and evolution of SNR’s amongst many other things.

For the Deep Sky Collective (DSC) “Cassiopeia A” was an interesting target as it lacks deep integrations and detailed looks from any amateurs, seemingly being forgotten about by non-professionals.
After our deep look at M51 we decided to split the DSC into 2 groups, one with big FOV’s and one with small FOV’s - this proved to be extremely useful as it enabled us to use the narrow FOV’s for Cassiopeia A. We ended up with a total of 13 people working on Cas A - 1 Editor, 1 stacker and 11 photographers.
Being determined to go deep and do Cas A some justice amongst amateurs, we started in mid August and ended up with a total of 525h 54min of integration after rejecting bad frames. This not only marks the longest integration time ever on Cas A from any group of amateurs, but also the longest integration time ever on a single panel here on astrobin and possibly even for all of amateur astrophotography (for the moment ). If anybody knows what is the most integration on a single image ever done let us know in the comments!

As the target lacked any good amateur observation we did not really know what to expect in our final stack - more on the results in a later section of the text. Other than not knowing what to expect in the final stack, we also did not know how to split the integration between channels. In the end we went for a traditional SHO palette as this is the traditional way to shoot SNRs and PNs. To our surprise the SNR has a relatively strong signal in Sii and Oiii and barely any signal in Ha - more on that later.
Just a few days before stacking we looked up some existing images of Cas A and saw that some parts of the SNR don’t show in narrowband but are broadband only (i.e emit light in wavelengths that we don’t have special filters for). As we only had a few hours of broadband by that point we shifted focus and got some more of it in the remaining time. In the end it wasn’t crucial but does add some value to the image.

[b]--- NEW DISCOVERY : Strottner-Drechsler Object 59 ---[/b]

Here is the first image of the object StDr59 :

[i]Copyright : Julien Dufour / Marcel Drechsler[/i]

This is a discovery by Xavier Strottner and Marcel Drechsler.
The data were collected by Julien Dufour.
The image was processed by Marcel Drechsler.

[u]A few words from Marcel Drechsler about StDr59 :[/u]

[quote]The object Strottner-Drechsler 59, officially registered under the catalog number PN-G: 196.9-01.5, is considered a possible planetary nebula with a diameter of 73.8 arcmin. The reason for this assessment was the conspicuous circular appearance and a potential central star (a probable white dwarf). The possible central star is slightly offset from the center of the nebula, but this is not an exclusion criterion, as the nebula could already be very old and the central star could have migrated out of the center due to its proper motion.

However, there are also other explanations for the round shape of StDr 59.
For example, it could be a bubble of interstellar ionized gas (ISM).
The signal of doubly ionized oxygen (OIII) that surrounds the bubble of ionized hydrogen (H-alpha) like an envelope is striking. This is usually reversed in planetary nebulae, so (OIII) is closer to the central star than H-alpha.

Hard to miss is a red-blue band of filigree filaments running through the left part of the image. This structure is a little-known supernova remnant - the MonoGem ring. With a diameter of more than two dozen degrees in the night sky, it is the largest known supernova remnant. The image shows the westernmost part of this titan and represents less than 1 percent of the total area of the MonoGem SNR.[/quote]

The Pleiades (also known as the Seven Sisters, the Little Mother or by the acronym M45 from Charles Messier's catalog) are an open cluster visible in the constellation of Taurus. This rather close cluster (440 light years) has several stars visible to the naked eye. In city environments only four or five of the brightest stars are visible, in a darker place up to twelve. All components are surrounded by light reflection nebulae, especially observable in long exposure photographs taken with telescopes of considerable size.

The star-forming region around NGC 6726 in the southern constellation of Corona Australis (Southern Crown) about 400 – 500 light years distant is a complex association of dust and beautiful blue reflection nebula. In the image, the globular cluster NGC 6723 is also seen. Though prospectively near the nebulae, its ancient stars actually lie nearly 30,000 light-years away, far beyond the young stars of the Corona Australis dust clouds.

I've just returned from Iceland, where I was with the 4th group of my Photo Tour through the Land of Fire and Ice. The greatest anticipation when thinking about a year-end tour in Iceland is the opportunity to photograph the Northern Lights at some of the country's major natural attractions, and there are plenty of them.
Each time in Iceland is different; the weather conditions vary greatly throughout the days of the journey, and on each occasion, we witness different situations in the places we visit. Despite this, we've been very lucky in the Kirkjufell mountain region, where in the last 3 expeditions, we had incredible weather and Northern Lights conditions.
This panoramic image was captured on November 9th, the second day of our expedition in Iceland. The day was amazing from dawn until night, when we had a spectacular Northern Lights show over Kirkjufell. Unfortunately, at the moment when the Northern Lights were strongest and most active, I couldn't take photos as I was assisting my students. A bit later, when it was weaker, I managed to capture this shot, and I was very happy with the result.
