After an aggravating day at the office, I decided to spend a little time out in the cold night air learning about low light photography. The Christmas lights on the house threw off a weird blue light that was magnified by the longer exposures. It certainly doesn't look this blue to the naked eye. I think these images look very interesting with the warmer starry sky in the background.

It has also been an education on how quickly the stars are spinning in the sky. Your exposure doesn't have to be very long before the star points become star dashes. The movement of the Earth due to it's rotation is much faster than you might realize.
