What seems to be a smudge gradually resolves in thousands of pinpoint stars swarming around a central nucleus. https://marktweedie.uk/portfolio/astrogravure/pinwheel-galaxy/ Sat, 16 Aug 2025 19:29:26 +0100 https://marktweedie.uk/portfolio/astrogravure/pinwheel-galaxy/ The Pinwheel Galaxy, or Messier 101, is a faint deep sky object at a distance of approximately 25 million light-years and is located outside of our own galaxy. https://marktweedie.uk/portfolio/astrogravure/tadpoles-nebula/ Thu, 14 Aug 2025 19:55:18 +0100 https://marktweedie.uk/portfolio/astrogravure/tadpoles-nebula/ The size of the Tadpoles is immense. Each measures in the region of ten light-years in length. For me they are a symbol of the out-bursting of life in our universe, still young at 4 million years old, lying at a distance of 12,000 light-years from Earth. https://marktweedie.uk/portfolio/astrogravure/pelican-nebula/ Wed, 06 Aug 2025 19:55:18 +0100 https://marktweedie.uk/portfolio/astrogravure/pelican-nebula/ Medium: Photopolymer gravure Paper: Hahnemühle Etching White 300g Date: 2025 Image size: 27.5cm x 36.5cm / 10.75in x 14.25in Size unframed: 40cm x 56cm / 15. https://marktweedie.uk/portfolio/astrogravure/pleiades-and-the-moon/ Tue, 01 Jul 2025 19:55:18 +0100 https://marktweedie.uk/portfolio/astrogravure/pleiades-and-the-moon/ On the 1st April 2025 the Moon crossed directly across the Pleiades star cluster making a beautiful scene of our nearest celestial neighbour with a backdrop of stars over 400 light-years away. https://marktweedie.uk/portfolio/astrogravure/western-veil-nebula/ Fri, 13 Dec 2024 06:52:53 +0100 https://marktweedie.uk/portfolio/astrogravure/western-veil-nebula/ The Western Veil is an astronomical photo printed as a photopolymer gravure or etching and is a combination of hi-tech and low-tech processes. The nebula is a remnant of a star which cataclysmically exploded some ten or twenty thousand years ago leaving behind huge trails of ionised gas. https://marktweedie.uk/portfolio/astrogravure/moon-copernicus/ Fri, 13 Dec 2024 06:56:42 +0600 https://marktweedie.uk/portfolio/astrogravure/moon-copernicus/ Copernicus is a beautiful and dramatic crater, easily seen in a small telescope. Its scale is not immediately obvious to the naked-eye observer, however the crater measures 93km in diameter with a central mountainous peak of 1. https://marktweedie.uk/portfolio/astrogravure/sinus-iridum/ Tue, 03 Dec 2024 20:56:42 +0600 https://marktweedie.uk/portfolio/astrogravure/sinus-iridum/ Sinus Iridum, the Bay of Rainbows. Medium: Photopolymer gravure Paper: Hahnemühle Etching White 300g Date: 2024 Image size: 16.5cm x 23.5cm / 6.5in x 9.25in https://marktweedie.uk/portfolio/astrogravure/moon-lunar-x/ Tue, 03 Dec 2024 20:56:42 +0600 https://marktweedie.uk/portfolio/astrogravure/moon-lunar-x/ This gravure is made from a charcoal sketch rather than a photograph. The lunar X is a clair obscur effect caused by the angle of the sun’s rays casting shadows of ridges between the craters La Caille, Blanchini, and Purbach in a specific shape on the lunar landscape. https://marktweedie.uk/portfolio/astrogravure/elephants-trunk-nebula/ Wed, 11 Sep 2024 19:55:18 +0100 https://marktweedie.uk/portfolio/astrogravure/elephants-trunk-nebula/ The Elephant’s Trunk is another stunning deep-sky object in Cepheus. It is almost as if the wise eye gazes back to us on Earth. Recipient of the RE Printmakers “Small But Mighty” exhibition 2025 Membership Prize https://marktweedie.uk/portfolio/astrogravure/cygnus-wall-with-meteor/ Wed, 11 Sep 2024 19:29:26 +0100 https://marktweedie.uk/portfolio/astrogravure/cygnus-wall-with-meteor/ The Cygnus Wall is a region of bright gas in the constellation Cygnus. On this particular night I was lucky enough to capture a streaking meteor at a perfect position in the frame. https://marktweedie.uk/portfolio/astrogravure/the-ghost-of-cassiopeia/ Wed, 11 Sep 2024 06:56:40 +0100 https://marktweedie.uk/portfolio/astrogravure/the-ghost-of-cassiopeia/ The Ghost of Cassiopeia is a reflection nebula, that is a cloud of instellar dust and matter illuminated by a nearby star. Medium: Photopolymer gravure https://marktweedie.uk/portfolio/astrogravure/horsehead-nebula/ Tue, 10 Sep 2024 20:56:42 +0600 https://marktweedie.uk/portfolio/astrogravure/horsehead-nebula/ The Horsehead Nebula, a mixture of dark dust and ionised hydrogen gas, is one of the iconic sights of the northern hemisphere. Adjacent to it is the Flame Nebula illuminated by the super-bright star Alnitak, the left-most star of Orion’s belt. https://marktweedie.uk/portfolio/astrogravure/astral/ Mon, 23 Dec 2019 20:56:42 +0600 https://marktweedie.uk/portfolio/astrogravure/astral/ Astral is a self-portrait composite image comprising a pinhole image of the figure and a widefield image of the Christmas Tree cluster and the surrounding starfield in the constellation Monoceros. /img/rss-icon.png https://marktweedie.uk/index.xml 32 32 Print and artworks
