"Carina over Lake Ballard"
Taken on Lake Ballard, Western Australia on 25/12/2017 - this image shows the signature hill that thrusts out from the dry salt lake, watched under the glow of the mighty Carina Nebula and the Southern Cross constellation. Lake Ballard is around 2 hours drive north of Kalgoorlie, with about 50km on a average dirt road (accessible by two wheel drive, which I did last year - but would recommend a 4x4).
On this night, the moon was at 40%, 20 deg elevation and descending therefore lighting up the foreground nicely - although at this brightness I had to back off alot on the exposure time to avoid whiting out the sky. Clouds were an issue as well, floating by occasionally. Fortunately, you can view this hill / lake from any angle so it was a matter of walking around such that the composition targeted a clear patch of sky.
This was a 22 panel mosaic but cropped to reveal closely the fantastic beauty of the Carina and Crux region of the sky. A tracking mount was used for the sky and turned off for the foreground. All camera and lens settings were kept the same for all panels. Stitching in PTGui, colour calibration, levels, saturation and contrast in Photoshop.
Enjoy, Will Vrbasso.

Crab Nebula round clock
The Crab Nebula, the result of a #supernova noted by Earth-bound chroniclers in 1054 A.D., is filled with mysterious filaments that are are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The #Crab #Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron #star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.

The Horsehead Nebula, a Magnificent Interstellar Dust Cloud
This nebula is a very well-known object and a popular target for observations, most of which show the Horsehead as a dark cloud silhouetted against a background of glowing gas.The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion, approximately 1500 light years from Earth.
It is located just to the south of the star Alnitak (designated Zeta Orionis, is a multiple star ), which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex.
It is part of Orion's Belt along with Alnilam and Mintaka.)
The nebula was first recorded in 1888 by Scottish astronomer Williamina Fleming on photographic plate B2312 taken at the Harvard College Observatory.
It is an extremely dense cloud projecting in front of the ionized gas that provides the pink glow so nicely revealed in this picture.
We know this not only because the underside of the 'neck' is especially dark, but because it actually casts a shadow on the field to its east (below the 'muzzle').
The marked change in the density of stars visible on either side indicates that the strip of glowing hydrogen marks the edge of a substantial dark cloud. As a cloud core emerging from its parental cloud, and as an active site of low-mass star formation, the Horsehead is a simple system of considerable use for testing models of photodissociation regions, and revealing the intricate interrelations between gas, dust, and the light from hot stars.
Here, the gorgeous color image combines both narrowband and broadband images recorded using three different telescopes.
Stars are forming within the dark cloud. Contrasting blue reflection nebula NGC 2023, surrounding a hot, young star, is at the lower left.
The darkness of the Horsehead is caused mostly by thick dust blocking the light of stars behind it. The lower part of the Horsehead's neck casts a shadow to the left. The visible dark nebula emerging from the gaseous complex is an active site of the formation of "low-mass" stars. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming.

Sharpless 29: Stellar Nursery Blooms into View
Also known as Sh 2-29, Sharpless 29 is located about 5500 light-years away in the constellation of Sagittarius (The Archer) and sits right next to the famous Lagoon Nebula. In fact, Sh 2-29, togheter with Sh 2-31 and Sh 2-32, is part of group of three nebulae next to the much larger Lagoon nebula. Sh 2-29 is the largest of the three. This group is combined together in the RCW (RCW 146c) and Gum (Gum 75) catalogs.
The European Southern Observatory (ESO)’s VLT Survey Telescope (VST) has captured a sparkling image of Sharpless 29, home to much embellishing star formation features. This sight brings together a diversity of astronomical phenomena, including young bright stars, illuminating gas and darkening dust.
The region of sky pictured is listed in the Sharpless catalogue of H II regions: interstellar clouds of ionized gas, rife with star formation. More precisely a H II region is a region of interstellar atomic hydrogen that is ionized. It is typically a cloud of partially ionized gas in which star formation has recently taken place, with a size ranging from one to hundreds of light years, and density from a few to about a million particles per cubic cm.
The hot young stars in this image are no more than two million years old and are blasting out streams of high-energy radiation. This energy heats up the surrounding dust and gas, while their stellar winds dramatically erode and sculpt their birthplace. In fact, the nebula contains a prominent cavity that was carved out by an energetic binary star system. This cavity is expanding, causing the interstellar material to pile up and create the reddish arc-shaped border.
The nebula at the centre of this picture, NGC 6559, contains all the fundamental molecules and elements needed to kick-start the birth of many massive stars. It shows both emission (red) and reflection (bluish) regions. In particular, the red glow is caused by the emission of energy from the most abundant gas in the universe, hydrogen. The blue light is caused by the reflection and scattering of starlight from small dust particles.
► More details at>> http://www.eso.org/public/news/eso1740/
► Image explanation:
The OmegaCAM imager on ESO’s VLT Survey Telescope has captured this glittering view of the stellar nursery called Sharpless 29. Many astronomical phenomena can be seen in this giant image, including cosmic dust and gas clouds that reflect, absorb, and re-emit the light of hot young stars within the nebula.

"The Great Carina Nebula" by Will Vrbasso (www.stellaraustralis.com)
My first session with my telescope for 2016 (and for a couple months), so I decided to pick an "easy" target (easy because it is bright and relatively simple to find and photograph). This image was taken from the dark skies of Namming Nature Reserve, Western Australia.
The Great Nebula in Carina is one of the largest diffuse nebulae in the night sky, and is four times larger and also brighter than the mighty Orion Nebula. It also contains the high luminous hyper-giant star Eta Carinae (100-150 times the mass of our Sun, and four million times as bright), the Homunculus nebula, the Keyhole nebula, and the Mystic Mountain (a dust-gas pillar made famous in a Hubble image).
This image was a quick stack of only 8 images with an unmodified Canon EOS6D through a Skywatcher 120mm apo telescope. I would've like to do more, but I had the moon rising and I needed to be quick.
Enjoy, Will.
PS: all my images are available to download on my website at www.stellaraustralis.com.
