katarn writes "Nick Risinger traveled the world, using a robotic camera mount and six air-cooled cameras, each fitted with their own lenses and filters, to capture the entire night sky in one image; the largest full true-color sky survey. The project took a year to complete, and Risinger logged 60,000 travel miles. The final image is made up of over 37,000 individual photos, has a resolution of 5,000 megapixels, and took months to piece together. Risinger says, 'Travel was necessary as capturing the full sphere of the night sky brought with it certain limitations. What might be seen in the northern hemisphere isn't always visible from the south and, likewise with the seasons, what may be overhead in the summer is below the horizon in the winter. Complicated by weather and moon cycles, this made for some narrow windows of opportunity which we chased through the remote areas of Arizona, Texas, Nevada, Colorado, California and Oregon.'"
