Imagers capture the sky
See all the entries of the 2009 Astroimaging Contest.
July 27, 2009
Astronomy's 2009 Astroimaging Contest was a resounding success. You can see all the winning submissions and read more about them in the September issue of Astronomy magazine. But we didn't have enough pages to print all the images we received, so we set up this web page to allow you to enjoy every picture.
GRAND PRIZE WINNER: To create this image, astrophotographer Tony Hallas made 10 vertical panels through a 14.5-inch telescope and nine horizontal “background” panels through a 6-inch Stellarvue telescope. Each vertical panel combined seven 25-minute exposures through L, R, G, and B filters; the horizontal panels combined five or six 20-minute exposures through L, R, G, and B filters. The total exposure time thus equaled approximately 19 hours, and the entire project (including image processing) took 4 months.
