الشرح: Winner in the 2023 IAU OAE Astrophotography Contest, category of Still images taken exclusively with smartphones/mobile devices.
In the serene landscapes of Lofoten, Norway on 28 March 2023, the sky was set ablaze by the aurora. The Northern (Southern) Lights, also known as aurorae, are natural light displays resulting from interactions between solar winds and Earth’s magnetic fields, as charged particles are redirected towards the north and south pole regions. In Norse legends, they are often depicted as a heavenly fire. In this scene, the celestial show is beautifully complemented by the silhouette of a lighthouse, as if the lighthouse ignited the mesmerising display overhead. Caught off-guard by this dazzling spectacle, the photographer swiftly captured the moment with a smartphone. This is a testament to the breathtaking surprises nature offers and the impressive capabilities of modern devices.

الشرح: Third place in the 2022 IAU OAE Astrophotography Contest, category Time lapses of celestial patterns.
This video tries to cover a huge variety of phenomena in the night sky from different locations — Iceland and China — and is designed like a theatre play, starring mother nature herself.
It starts with a blue twilight sky that dims and unveils the starry night sky on the stage with terrestrial clouds on a beautiful landscape. The impressive parts of the southern Milky Way between Scorpius and Crux, with the pointer stars Alpha and Beta Centaurus, are shown passing by majestically. The terrestrial clouds blur the stars and allow us to recognise their colours even more clearly.
The first act presents the starry sky in human culture. One scene shows the Pleiades rising over the top of a hill, while a human moves hastily with a flashlight below. At the very moment that the Pleiades rises behind the hill, the beam of the flashlight hits the camera. There is some humour in this remarkable scene referencing the human relationship to the rise of the Pleiades in cultural history.
The next scene shows The Big Dipper, Ursa Major, as a typical northern constellation, with an arch of aurora below it. The aurora evolves and moves but does not change much fundamentally. In northern human cultures, aurorae were often interpreted as the ghosts of ancestors, but this play does not spend any time on human beliefs, instead moving the view southwards in the subsequent scenes. First we see some stars rising shortly before sunrise. The lightcone of Zodiacal light appears in Gemini/Taurus and the horizon gets brighter. In the next scene, at about 1 minute and 13 seconds, we see Orion setting over water, so that the water surface mirrors the celestial scene. Some clouds crossing the image prove that the videos were really taken on our beautiful planet, and, since Orion’s shoulder and foot are seen to set almost simultaneously, this sequence must have been captured almost at the equator. In this area, the bright stars of Orion look like a huge butterfly, with Orion’s Belt forming the body, and the quadrilateral of four bright stars interpreted as the wings.
As in a real theatre, we now see a curtain before the next act of the heavenly play, an aurora curtain. The next act presents several bright stars in original scenes: the Chinese asterisms of The Tail (of the Azure Dragon), the Winnowing Basket and the Southern Dipper, which are seen in the modern constellations Scorpius and Sagittarius. The striking shape of Corona Borealis that has been recognised as an asterism in many cultures all over the globe, is also shown, as are some planets, the stars Vega and Deneb with adjacent areas, Altair, the Milky Way, and the characteristic W shape of Cassiopeia that has also been an asterism for many cultures on Earth.
The outro presents two more scenes with a smooth and silent night sky.

The Big Dipper in the Polar Night
فيديو
أُنشئ لصالح OAE
الشرح: Third place winner in the 2023 IAU OAE Astrophotography Contest, category of Time-lapses of rotation of Big Dipper or Southern Cross.
Step into the cosmic theatre of Iceland’s northern skies in this time-lapse where the illustrious Big Dipper commands attention, tracing an almost complete circle around Polaris — an exquisite sight that is not visible from mid-latitudes. This time-lapse, captured through fisheye lenses, reveals the timeless choreography of the Big Dipper, vividly illustrating its celestial waltz. Amidst this spectacle, the Arctic night reveals its grandeur, painting a panoramic canvas that showcases not just the celestial journey of this iconic asterism but also the ethereal dance of the Northern Lights. In this breathtaking tapestry, the Big Dipper takes centre stage against the mesmerising backdrop of the Icelandic nightscape, adorned by the vibrant hues of the Aurora Borealis.
