Nightscapes especially stars really fascinate me. I wanna capture "Aurora" once. Cool picture BTW. Try to make your frame without the electric wires. They distract.
Here's a startrail I took last year. There was a road and I didnt notice when I set my camera but them some cars passed through the road and so you can see the burning horizon. Over a period of 2 hours I took around 90-100 shots of 6-10 seconds and then stacked them. It was a no moon night.
