The Spaghetti Nebula

Catalogued as Sharpless 2-240, this faint supernova remnant goes by the popular nickname, the Spaghetti Nebula. It is fairly large (150 light years across) and located 3000 light years away toward the boundary of the constellations Taurus and Auriga. Light from the massive stellar explosion first reached Earth 40,000 years ago.

The violent stellar explosion that created the Spaghetti Nebula left behind all that remains of the original star’s core: a spinning neutron star known as pulsar PSR J0538+2817, surrounded by intricate filaments of material. This expanding remnant has an expansion rate of about 950 kilometers (nearly 600 miles) per second.

Total integration: 41h 45'

Abell 1060 - The Hydra Cluster

Copyright: Nicolas Adriano

Image URL: https://cdn.astrobin.com/images/67318/2 ... af7c3c.jpg
Abell 1060 - Hydra Cluster TL LRGB CHI-1.jpg
The largest spiral galaxy in the Hydra Cluster is NGC3312, which is located 194 million light years from Earth, and spans itself for 171,000 light years. To give you some perspective of how big and how far this galaxy is:
Photographing such a big object located that far away, is the same as photographing a 2 meter tall person 2 kilometers away. Or, the same as photographing a 10 centimeter pen 113 meters away.

Hello and welcome to Starship Asterisk*! :D That's a fine picture! :D

NGC 253 annotated Ehsan Ebrahimian.png

1) Is that an open or a globular cluster?

2) Is that a globular cluster?

3) Wow, that seems to be a large widespread open cluster (or association) that seems to have formed from outflows of gas from the center of NGC 253! Amazing!

4) That's a nice nebula!

IC 342 - The Hidden Galaxy of Camelopardalis
https://chaoticnebula.com
Copyright: Daniel Feller A beautiful galaxy that doesn’t get much recognition. IC 342 lies very close to the Milky Way, between 7 million and 11 million light years away. However, from Earth’s perspective, we have to peer through the dusty area of the galactic equator to see IC 342, which can obscure the visibility. This is why the galaxy is sometimes referred to as The Hidden Galaxy. However, even with the line of site through the galactic equator, IC 342 stands out. IC 342 does not belong to the local group of galaxies. Instead, it leads the IC 342 group, which is the closest group to our Local Group.

Image Details: 60*600 seconds Red, 60*600 seconds Green, 60*600 seconds Blue, and 30*600 seconds through HA Filter (35 hours total).
Dates Taken: Over 11 nights through Sept/Oct 2021
Location: Suburbs of Minneapolis
Telescope: Meade 12” LX200
Mount: Losmandy G11T

Thanks :D

here is a larger size of that region:

I think the both 1&2 are globular clusters. Open clusters are all around, which is consistent with the starburst nature of this galaxy.

An omega moonset’s continuous change
The inferior mirage of celestial bodies rising or falling from the sea level is the most special and beautiful mirage. This is a special phenomenon that occurs when there is a low-density layer of hot air on the surface of the earth or ocean due to refraction. The most common one is the sun’s inferior mirage. The moon’s inferior mirage is not common because it is dark, but if you have the opportunity to see the moon’s inferior mirage, you can just use the terrain and potholes on the moon to confirm the mirage with inverted shape!
The weather was good on November 10th, and I was lucky enough to meet the rare inferior mirage of the sinking moon! When the moon is very close to the sea level, the inverted virtual image below will form and slowly rise and connect with the upright image above to form a rare sight like an Etruscan vase or Omega (Ω) shape !
This combined picture includes the appearance of the lower mirage, the rising, and the connection with the upright image above, like an Etruscan vase. Then the bottleneck of the vase becomes thicker and shorter, and finally only a corner disappears on the sea surface.
Link to the time-lapse video where the mirage appears under the moon and is connected to the upright image: https://youtu.be/49HA67u_f20

Hubble's view of M82 by William Ostling, on Flickr

A full write-up with processing steps can be found here: "https://theastroenthusiast.com/hubbles- ... messier-82

Also known as the Cigar Galaxy because of its appearance, Messier 82 is a starburst galaxy with a superwind. In fact, through supernova explosions and powerful winds from massive stars, the burst of star formation is driving the stunning red outflows. This image highlights emission from filaments of atomic hydrogen gas in reddish hues. The filaments extend for well over 10,000 light-years.

I would highly recommend viewing this image on gigapan, where you can zoom in to the full resolution. http://www.gigapan.com/gigapans/227686

M51 in H-alpha and continuum light

M51 (also known as Whirlpool Galaxy) are two interacting galaxies in constellation Canes Venatici. The larger one (M51A or NGC 5194) is a spiral galaxy, the smaller companion (M51B or NGC 5195) is a distorted a dwarf galaxy.

The image is calculated with and without H-alpha information. By toggling between the two variants the correlation between HII gas clouds and bluish regions (containing young stars and probably also OIII gas) can be visualized.

IC410 - The Tadpole Nebula
Seen above is IC410 in the SHO color palette. IC 410 is a faint and dusty emission nebula of more than 100 light-years across approximately 12,000 light-years away from Earth in the northern constellation of Auriga. Notable are two streamers of material, known as the “Tadpoles of IC 410”. These tadpoles, which consist of denser, cooler gas and dust, are approximately 10 light-years long and potentially sites of ongoing star formation. They are almost in the center of the image.

Omicron Persei Star Forming Region

https://www.flickr.com/photos/147135308@N08/51679752596
Copyright: Christian Koll

Competing with nearby deep sky attractions like the California Nebula or the Pleiades star cluster, the region around Omicron Persei unfortunately does not get the attention it truly deserves. Only a deep exposure reveals the vast amounts of dust and gas that are in the process of gravitational collapse, forming new stellar objects. While many protostars are still hidden within their dusty enclosure, a young star cluster - IC 348 - has already emerged. Also standing out from the background of reddish hydrogen gas is Barnard 3, a prominent dark nebula discovered by Edward Barnard in the early 20th century.

Stack of 110 exposures at f/5.5 totalling approximately 8 hours.
Taken during 4 nights in Sptember, October and November 2021 in rural Upper Austria with a QHY600C-PH and a Skywatcher Espirt 100 at 550mm focal length. Tracking with Skywatcher EQ6-R, autoguiding with MGEN-3. Processed with Astro Pixel Proxessor, Starnet++ and Photoshop.

Best regards!
