Star Streaks

I'm still trying to learn how to do star streaks properly. Guess what? There is no proper way to do it, but there are MANY ways.

Last night I set my tripod up on the deck and took exactly 200, 21.9 MB, 30 second exposures. My laptop choked on it, but my desktop was successful in putting them all together.

The tree was occasionally illuminated by a motion light which brings the tree out too far.

I'll get a plan down on thjis soon.
