#2... I like the star trails in this and and the colors used in them. I like the color gradient in the sky and the downtown buildings, but I think that may be too detailed for some of the uses for the logo. I like the font on downtown, but maybe go with Trajan Pro if you have it. I don't really like the font on Star Trails, I think it may be a little to "Sci-fi". Awesome job on the star trails. Maybe do something where the name is bigger... more prominent.
I like #2 better than #1
