After reading a few messages about Joe and his generator, I thought I would start a new email message about this. I have a netbook computer. This is one of those really small laptop computers. It has a 10.6" screen and the battery runs for about 6 hours. So when I'm out observing, I run Stellarium and have some music playing lightly. I got mine at Costco for $300 so they're pretty inexpensive. ++++++++++++++++++ Troy Davidson Am I working - http://www.istroyworking.com
