I got both, but I'm not sure how.

The first image is a 64 second exposure and the stars are sharp (but the image is low quality for hosting). The second image is a 30 second exposure of a different section of sky. The 64 second exposure is the best and sharpest star picture I've taken yet but I don't know why.

Sometime between the two images I adjusted my focus to make sure it was at infinity; I think I pushed it past infinity.

I want to be prepared to take sharp star pictures outside of the light polluted suburbs when I travel. Please help!
