Why it’s the biggest digital image I’ve ever opened on a computer, the biggest and most beautiful image of a nebula and the highest resolution photo (even better than the Hubble Deep Field) I’ve seen. Warning: don’t download and open the image if you’re on a slow computer. Even on my AMD Turion II P546 dual core 2.4Ghz laptop with 6Gigs of RAM took 20 seconds to open it in IrfanView.
Granted this isn’t the largest image ever on the Internet. That honor probably belongs to the version of the Blue Marble adapted by IIPImage. But the nebula is still more attractive.
