Rivelati i vincitori dell'Astronomy Photographer of the Year 2019

Il Royal Observatory Greenwich ha rivelato i vincitori del prestigioso concorso Insight Investment Astronomy Photographer of the Year 2019 e, come sempre, le immagini vincenti sono spettacolari.

Quest'anno il concorso ha ricevuto oltre 4.600 fotografie scattate in 90 paesi in tutto il mondo. I giudici avevano il compito non invidiabile di identificare un vincitore, un secondo classificato e "menzioni speciali" per ogni categoria, un vincitore per la categoria "Robotic Scope" e un vincitore per il nuovo premio Sir Patrick Moore per la categoria "Best Newcomer".

Il premio pricipale è andato al vincitore della categoria "Our Moon", il fotografo ungherese László Francsics , che ha combinato 32 esposizioni multiple in questa splendida ripresa dell'eclissi lunare totale su Budapest, in Ungheria, il 21 gennaio:

Descrizione per gentile concessione del Royal Observatory Greenwich:

"The phases were so close together that they blended perfectly in a continuous image that captured the shadow of the Earth. On the edge of the shadow appears a rare blue tint, the shadow of the Earth’s ozone layer. The sequences were taken with 3-minute gaps using a pre-programmed shutter remote. They were stacked onto each other using the faint background stars as a guide, so that the photographer could reveal the real orbit of the Moon."

Young Astronomy Photographer of the Year

Fiore stellare © Davy van der Hoeven

"Once the photographer decided to capture a deep sky image, he started researching online for nebulae and came across the magnificent Rosette Nebula. With the help of his father he built the equipment and together, over three nights in November, captured images images of the Rosette Nebula using different filters. In order to familiarise with processing images, the young photographer practised on one of his father’s older photographs and then processed the raw data of this image by himself."

Aurorae Winner

The Watcher © Nicolai Brügger

"The photographer hiked in the snow to the top of the mountain Offersøykammen in Norway, to witness and capture the breathtaking giant aurora over the Lofoten Islands. He waited many hours and after midnight the bright Northern Lights finally appeared. The photographer shot this as a panorama to showcase the arched aurora over the mountains."

Galaxies Winner

Shells of Elliptical Galaxy NGC 3923 in Hydra © Rolf Wahl Olsen

This is a deep image of the peculiar, elliptical galaxy NGC 3923. The galaxy features myriad concentric shells as a result of past mergers with other nearby galaxies. Recent research has documented 42 concentric shells in NGC 3923, more than in any other known galaxy. A prominent stream of stars extends towards the lower right, terminating abruptly in a shell-like fragment. Within the stream lies a small round galaxy believed to be one of the progenitors of the shell system. Now in the process of falling back towards the centre of NGC 3923, it shows a comet-like tail of stars extending behind it. Scattered throughout the field of view, far in the distant background, are numerous other galaxies. Some are even visible through the diffuse glow of NGC 3923. Many lie several billion light years away.

Our Sun Winner

A Little Fireworks © Alan Friedman

A close-up of the solar limb with what looks like fireworks in the solar minimum period of the Sun’s cycle. A group of prominences are silhouetted against the background of space. The tonality has been inverted to express depth and contrast of the features in the Sun’s chromosphere. The data, captured with a monochrome (black and white) camera, has been colourised.

People and Space Winner

Ben, Floyd & the Core © Ben Bush

The image depicts the photographer and his dog, Floyd, surrounded by Mars, Saturn and the galactic core of the Milky Way galaxy. This photo encapsulates the photographer’s love for the cosmos. As his constant companions, the photographer often tries (and fails) to capture his dogs at night. With this shot the shutter speed was reduced to 10 seconds to allow to keep Floyd still. To counter this, the ISO was increased and the photographer whispered ‘don’t move, don’t move, don’t move’ to Floyd for the whole 10 seconds. The shot was repeated a number of times in order to capture a clear silhouette in a single exposure shot. The image contains everything the photographer loves about photography; the relationship with the landscape, family, dogs and friends.

Planets, Comets and Astroids Winner

Death of Opportunity © Andy Casely

This is a sequence of images through the perihelic opposition of Mars in 2018 that follows the progress of the great global dust storm, which proved to be detrimental for the Opportunity Mars rover, which exceeded its planned lifespan by 14 years. The first frame (26 May) precedes the storm, with clouds on volcanoes in the Martian spring. The storm rapidly grew from regional to global coverage between 6 and 11 June (second and third frames), obscuring Opportunity, and only the Tharsis volcanoes were peeking out by 3 July. After a close July opposition, with features such as Syrtis Major only dimly visible through the dust, the usual darker albedo features returned as Mars disappeared into the distance again, while the south polar cap shrank into Martian summer.

Robotic Scope Winner

Infrared Saturn © László Francsics

With this image, the photographer decided to take on the challenge of revealing the very near infrared colours of Saturn, using the combination of the red and other two infrared planetary filters, the IR 685 and the IR 742, respectively. These are usually taken using special infrared planetary filters, in order to reduce the perturbation effect of the atmosphere, and RGB filters, to show the visual appearance of the planet. This choice of filters meant the photographer could push the limits of amateur astrophotography a little further. In doing so, he managed to shift the spectral range of the coloured image with 0.4 microns (620–1150 nm) towards infrared.

Skyscapes Winner

Across the Sky of History © Wang Zheng

This mystical image of withered poplar trees was taken in the Mongolian region of Ejina, in the historical Kingdom of Xi Xia. The poplars’ resistance to erosion has led to an extraordinary formation of a desolate landscape and as a meteor falls, their shapes look like ancient creatures on an uninhabited desert.

Stars and Nebulae Winner

Statue of Liberty Nebula © Ignacio Diaz Bobillo

These are two nebula complexes, far apart from one another. The one on the right, NGC 3576, is closer to Earth, and its shape provides the title of this image. Both are active stellar nurseries, lit and shaped by the radiation from energetic young stars, showcasing a spectacular array of structures and colours. Acquired with narrow band filters, the composite image colour scheme follows the three-colour Hubble Palette standard.

Best Newcommers Prize

The Jewels of Orion © Ross Clark

This is an image that the photographer wanted to capture since starting astrophotography in September 2018. This strip of the Orion constellation includes some of the best targets in the Northern Hemisphere. According to the photographer, the image shows what can be done with a pretty average DSLR camera and a lens and is hopefully an inspiration to those who have some photography kit already and want to get started. The image is a mosaic of two panes at 200 mm. Both panes were stacked in PixInsight, and have same basic early processing of gradient removal and colour calibration. Both images were then transferred and stitched together in Photoshop with further work done to reduce noise, bring out the dust and control the stars’ size and colour.

Sky and Ground, Stars and Sand © Shuchang Dong

The Moon was shining bright over the sand dunes in north-central China, when the photographer decided to capture this image with a friend. After enjoying a sunset and the rise of the Moon, they began to take photos of the magnificent starry sky.

Ningxia, China, 25 July 2018

Le immagini vincitrici, i secondi classificati e le immagini menzionate saranno esposte insieme a una selezione di 68 fotografie selezionate in una speciale mostra di Astronomy Photographer of the Year al National Maritime Museum.
