Star Trails I

Posted by
Bill Brown (California, United States) on 25 May 2009 in Miscellaneous and Portfolio.

This is a test image to refine my parameters for creating star trails. This was a 30 min. exposure at f8 and ISO 200, which proved to be too much. I reduced exposure by 2.5 stops in processing to yield this image. Granted this isn't exactly a great image, but it gives me a starting point. I welcome your comments and/or suggestions.

Using the North star as a central point is always good and get far away as possible from any street lighting.

I agree, Bill - a very good start. Use a neutral density filter if you need to. I've used a polarizer in a pinch. You obviously got a sturdy tripod. The best advice you've already figured out - go long!

@Stephen Phillips: Thanks for your comments and advise. I will be trying again this week but I'm going to go for a 60 minute exposure. I also need to get away for some of the city light pollution. This shot is from my backyard.
