SkySafari Pro 1.8

SkySafari Pro contains the same feature set as SkySafari Plus, but includes a hugely-expanded database: 15 million stars from the Hubble Guide Star Catalog, 750,000 deep sky objects, and over 550,000 solar system objects - including every comet and asteroid ever discovered. It's geared toward advanced amateur observers who simply want everything available in a mobile astronomy package.
