Distant Suns: 16 million stars for free
First, please take a couple of minutes to sign up for my monthly astronomy newsletter (this is optional). This will give you tips on what's happening each month in the heavens and how to more effectively use Distant Suns. Not to mention special sales from time to time. All data is privately held and will not be released to other parties. Goodness knows, I get spammed enough, I'm not going to aid others doing the same (check out McAfee's Spamkiller, it's great!):
