Top Ten Deep Space Objects

I created this illustration with input from my astronomy professor husband for the "Out of this World" challenge at www.theydrawandtravel.com. I asked for his ten favorite astronomical objects, and created the individual illustrations in watercolor and digital drawing. Some of these objects, like the Pleiades, are visible with the naked eye; others, such as the Eagle Nebula, have been beautifully photographed by the Hubble Space Telescope.
