Traveling under a galaxy of fireflies in this Moontrailscape. It's really nice to see how they shine during twilight.

This was shot before Geminids on Dec 13. That night it went cloudy.

Essentially a blue-green egg shaped cloud with two distinct and intricate red Halpha jets emanating from each end, NGC 1360 is an unusual
but beautifully subtle egg shaped planetary Nebula in Fornax. It floats majestically in front of a wide spread of distant background galaxies.

Startrails at the Danube ("Virtual Reality")
Copyright: György Soponyai

This photo is my second experiment in playing with the just-launched Flickr Virtual Reality tool. I didn't expect to reuse the original photo such a way so that the bottom is missing as I positioned my camera slightly upwards in order to have some overlapping of the star stripes in the zenith.

This all-sky startrail photo was taken between 17th and 24th August 2014. Dömös is a village in the Danube Bend (Dunakanyar) located 45 km north from Budapest. The Dunakanyar is often considered as one of the most beautiful part of river Danube where it flows between Börzsöny Mountain and Visegrád Mountain.

I started the project on evening of 16th August by taking two hours of exposure turning the camera to northern direction towards the Börzsöny Mountain however the air was very humid and cloudly and I was not sastisfied with the poor result. The next two nights the sky was crystall-clear so I went on photographing the southeastern and southwestern part of the scene. Every night I started the photo sessions four minutes earlier so the visible position of stars were the same.
On the third night many friends of mine joined for baking some bacon, you can spot us in the southern part of the photo near the campfire.

When I started processing the raw images it became obvious that it's impossible to make a good-looking result by using the first night's photos. So I went back to Dömös on 24th August in order to re-take the photos of the northern sky. In the previous six days the water level of the Danube decreased making the photo alignment complicated. But here is the result at last.

Geminids over LAMOST telescope

Space dust from asteroid 3200 Phaethon rained into the Earth's atmosphere,and burnt as meteors at about 100 km above Xinglong Station of National Astronomical Observatories of China, piercing the night sky over the Guoshoujing LAMOST telescope.

All meteors seemed to radiate from the same point, which lies at Gemini, and that’s how the meteor shower named Geminids.

Over 100 meteors were captured in the composed image taken on the peak night of the 2015 Geminid meteor shower, and the brightest bolide even instantly lit up the landscape.

This is Hydrogen Alpha data and covers more than 12 Full Moons (6 degrees) on the sky with North to the left.
The field includes emission region Sh2-227 top left, IC 405 (top center) about 1,500 light-years distant. Also known as the Flaming Star Nebula, its Hydrogen Alpha convoluted clouds of glowing hydrogen gas are energized by hot O-type star AE Aurigae. Slightly to the below is M38.
IC 410 (below center slightly right) is significantly more distant, some 12,000 light-years away. The star forming region is famous for its embedded young star cluster, NGC 1893, and tadpole-shaped clouds of dust and gas. IC 417 and NGC 1931 at the lower right.

Lulworth Cove is a cove near the village of West Lulworth, on the Jurassic Coast World Heritage Site in Dorset, southern England. Apart from its unique geomorphology it is an ideal target for Winter Solstice photography. From this vista it spans 115 degrees across the southern horizon whereas the Sun covers 103 degrees from sunrise to sunset at this latitude during the shortest day of the year.

Five photos stacked during the whole day at 20/12/2015, two days before the Winter Solstice.

Merry Christmas and a happy new year!

Deep optical image of Malin 1

We present Megacam deep optical images (g and r) of Malin 1 obtained with the 6.5m Magellan/Clay telescope, detecting structures down to ~ 28 B mag arcsec-2. In order to enhance galaxy features buried in the noise, we use a noise reduction filter based on the total generalized variation regularizator. This method allows us to detect and resolve very faint morphological features, including spiral arms, with a high visual contrast. For the first time, we can appreciate an optical image of Malin 1 and its morphology in full view. The images provide unprecedented detail, compared to those obtained in the past with photographic plates and CCD, including HST imaging. We detect two peculiar features in the disk/spiral arms. The analysis suggests that the first one is possibly a background galaxy, and the second is an apparent stream without a clear nature, but could be related to the claimed past interaction between Malin 1 and the galaxy SDSSJ123708.91 + 142253.2. Malin 1 exhibits features suggesting the presence of stellar associations, and clumps of molecular gas, not seen before with such a clarity. Using these images, we obtain a diameter for Malin 1 of 160 kpc, ~ 50 kpc larger than previous estimates. A simple analysis shows that the observed spiral arms reach very low luminosity and mass surface densities, to levels much lower than the corresponding values for the Milky Way.

"Finger of God"
by Iván Sánchez




In this picture I wanted to join the sentimental symbolism of the Milky Way with one of the most characteristic symbols of religion.

This photograph is made in an abandoned village, and received the punishment of civil war in Spain. In fact, this cross is called "the Cross of the Fallen". The goal was to unite all these elements in a photograph.

Technically, a single shot with a Canon 5D Mark III was performed with ISO 3200, f / 2.8 to 30 seconds of exposure. With noise reduction from the camera and further processing for the detail in the galactic center.

From behind the cross, it has brought to light a torch to provide continuity in the light of the Milky Way, and separate cross background, giving a mystical atmosphere.

Let me know if you need more information about this picture or more resolution.

Best Regars.
