Total solar eclipse
GRAND PRIZE WINNER: Total solar eclipse (3-inch Pentax 75 SDHF apochromatic astrograph, Canon EOS 50D DSLR, exposure times varied from 1/125-second to 2 seconds, at ISO 100 and ISO 200, 53 of 82 images taken during totality were used, taken July 11, 2010, between 18h41m38s UT and 18h44m36s UT, at Hao Atoll in French Polynesia)
Thomas Bader

The results are in. Four individuals from four countries took home the prizes in Astronomy magazine’s 2010 Astroimaging Contest. Astronomy editors chose the winning images.

The overall winner is Thomas Bader of Rheinfelden, Germany. His image from Hao Island in French Polynesia of the eclipsed Sun taken during the July 11, 2010, total solar eclipse shows incredible detail, both in the Sun’s corona (outer atmosphere) and on the Moon’s surface, where features shining from light reflected off Earth are easily visible during totality. For his image, Bader wins a Celestron CPC 1100 GPS XLT 11-inch Schmidt-Cassegrain telescope.

The Milky Way
GENERAL CATEGORY WINNER: The Milky Way (Canon EOS 5D DSLR, 24mm lens at f/1.4, ISO 1600, nine images form this 3×3 matrix, the top six images are 30-second exposures, the bottom three are 60-second exposures)
Tunç Tezel

The winner in the General category is Tunç Tezel of Bursa, Turkey. His image of the southern Milky Way from Mangaia, one of the Cook Islands in the South Pacific, shows the closest star system to Earth, Alpha Centauri, the Southern Cross, the Magellanic Clouds (two of our galaxy’s satellites), and thousands upon thousands of other stars. Tezel wins a DMK 21AU04.DS CCD camera courtesy of Imaging Source.

The Leo Trio
DEEP-SKY WINNER: The Leo Trio (5.6-inch Telescope Engineering Company TEC 140 apochromatic refractor at f/7, Quantum Scientific Imaging QSI-583wsg CCD camera, LRGB image with exposures of 90, 70, 40, and 40 minutes, respectively)
Ruben Kier
In the Deep-sky category, longtime Astronomy magazine contributor Ruben Kier of Orange, Connecticut, bested the competition. His superb image shows three galaxies — M65, M66, and NGC 3628 — collectively called the Leo Trio because of the constellation in which they reside. Kier wins a DMK 41AU02.AS CCD camera from Imaging Source.
Eclipse sequence
SOLAR SYSTEM WINNER: Eclipse sequence (Canon EOS 30D DSLR, Canon EF 16-35mm f/2.8L II lens, set at 16mm, combination of 32 images, most at f/8 and 1/500-second exposure, totality at f/4 and 1-second exposure, taken July 11, 2010, every 5 minutes starting at 7:28:06 local time, at Hao Atoll in French Polynesia)
Li-Chun Chen

Top honors in the Solar System category go to Li-Chun Chen of Taipei, Taiwan. He combined 32 exposures of the July 11, 2010, total solar eclipse from Hao Island in French Polynesia into one dramatic image that documents the event. Chen wins a DMK 31AU03.AS CCD camera contributed by Imaging Source.

Astronomy magazine Photo Editor Michael E. Bakich talked enthusiastically about the participation: “This year’s entries — 77 in all — went way beyond expectations. I received submissions from longtime contributors and also from many people who had never sent the magazine an image before.”

Subscribers have access to galleries containing all official entries in each category. And as a bonus, look for the four winning images in the Reader Gallery section of our April 2011 issue.
