The Pillars of Darkness

This is the Barnard 22 region shot under Bortle 1 skies of the 2021 Okie-Tex Star Party in Western Oklahoma. I spent 6 nights in total shooting once it had risen high enough, primarily focusing on Luminance, though the transparency conditions were mediocre to poor most the week so out of 26 hours total I only used about 16. I found the shape of this nebula reminiscent of M16's Pillars of Creation, leading to my contrasting title, though when viewing the image upside-down I can also see a shape resembling Sauron's fortress of Barad-dûr. One curiosity I found was 6 small smudges evenly placed in the corner of the stacked images (which were carefully clone stamped out), indicating a slow-moving object - after querying a JPL site I found that 322 Phaeo, a 70km-wide asteroid discovered in 1891, was moving through the area during the star party (see Annotated image link below)

Messier 51 from Hubble by William Ostling, on Flickr

The graceful, winding arms of the majestic whirlpool galaxy appear like a grand spiral staircase sweeping through space. They are actually long lanes of stars and gas laced with dust.

This sharpest-ever image of the Whirlpool Galaxy illustrates a spiral galaxy’s grand design, from its curving spiral arms, where young stars reside, to its yellowish central core, a home of older stars. The bright pink regions display large bursts of H-alpha, where new stars are formed.

I would highly recommend viewing this image on gigapan, where you can zoom in to the full resolution. http://www.gigapan.com/gigapans/227620

NGC 660. KG Observatory, Julian, CA.

"NGC 660 is a peculiar and unique polar-ring galaxy located approximately 45 million light-years from Earth in the Pisces constellation. It is the only such galaxy having, as its host, a "late-type lenticular galaxy".It was probably formed when two galaxies collided a billion years ago. However, it may have first started as a disk galaxy that captured matter from a passing galaxy. This material could have, over time, become "strung out" to form a rotating ring.

The ring is not actually polar, but rather has an inclination from the plane of the host disk of approximately 45 degrees. The extreme number of pinkish star-forming areas that occurs along the galaxy's ring could be the result of the gravitation interaction caused by this collision. The ring is 50,000 light-years across - much broader than the disk itself - and has a greater amount of gas and star formation than the host ring. This likely indicates a very violent formation. The polar ring contains objects numbering in the hundreds. Many of these are red and blue supergiant stars. The most recently created stars in the ring were just formed approximately 7 million years ago. This indicates that the formation of these stars has been a long process and is still occurring.

Data about the dark matter halo of NGC 660 can be extracted by observing the gravitational effects of the dark matter on the disk and ring's rotation.From the core of the disk, radio waves are being emitted. The source of these waves is an area only 21 light-years across. This may indicate the presence of a super-cluster of stars located within an area of cloud of gas. The region in the centre has a vast amount of star formation, so luminous that it is considered to be a starburst galaxy.

Late in 2012, this polar-ring galaxy produced an enormous outburst having a magnitude of approximately ten times brighter than a supernova explosion. The cause is not certain, but this event may have resulted from a tremendous jet being emanating from galaxy's central black hole."

The silence spreading along the front lines on 11th of November 1918 marked the end of the bloodiest conflict mankind saw up until that point. Millions were not lucky enough to witness the end of 4 years of hell. My image honors them all.

More than 8500 Austro-Hungarian and Russian soldiers are lying in their eternal rest near the village of Veľkrop, in the largest WW1 cemetery in Slovakia. Nature paints a beautiful scenery for the men, who knew so little peace and quiet in their final days.

Space Valley

My camera decided to shoot this tree all night long. That's what happened! Heart's movement make a little trail in the stars, recorded by the sensor. The sum of 305 shot, each one of 47 seconds, made this kind of effect, a Startrail.
I shoot from 00:30 till dawn at 4:30am.
After a long night shooting milky way, I really want to shoot this startrail and I found quickly this spot, because I was really tired. We are in Pollino National Park, on peak Serra Di Crispo, 2050m above sea. This tipical tree, Pino Loricato, was looking the valley of Piani del Pollino for many many centuries!
After the shooting started, I came back to my tent near the spot for enjoy a really cold night. All my friends are sleeping so.. Shh!

M77. KG Observatory, Julian, CA.

Object 2 of 2 from my October/November dark cycle.

Here I used 5-minute L subs to help expose more of the very bright core. The spirals emminating from the core looked to be a bit stronger in the R channel. 45 minutes of screened Ha helped highlight that.

All processing uses 2x Drizzle to help increase resolution for a narrow shot. (-:

"Initially identified as a nebula by the French astronomer Pierre Méchain in 1780, M77 is one of the largest galaxies in the Messier catalog. It is located in the constellation Cetus at a distance of 45 million light-years from Earth.

M77 is a prime example of a Seyfert galaxy, or a galaxy with an intensely active center that is obscured by gas and dust in visible light.

Only one supernova has been detected in Messier 77. The supernova, named SN 2018ivc, was discovered on 24 November 2018 by the DLT40 Survey."

Traveling through the valleys of Saint Catherine at day and capturing the majestic Rho Ophiuchi cloud complex at night was my routine in the last few nights.
I was lucky getting few of them while capturing the beautiful bortle 1 night sky of Egypt. This image was shot using my beloved portable setup with no complications just a tracker, stock dslr, 135mm lens, and most importantly patience.
Location: Dar Eid - Saini - Egypt.
Date: August 11/12/13.

I always look forward to your images, and you never disappoint! :D

That's a great portrait of M77! I love the fact that you bring out so much of the outer faint parts of M77. If you compare it with a NASA/ESA image, it only shows the bright inner spiral of M77. And those that show as much of the outer parts of the galaxy as your image does overexpose the bright inner bulge more than you do. In short, this is a superb image! :D

The stars like dust. This is a zoom-in the Milky Way region near Caph in Cassiopeia. Image taken on 2 x Canon 200mm lenses. Usually pictures of the Milky Way look like beautiful cloud-like structures. I have not seen a close-up like this before where you can see just how many stars are packed together.
