Well this is my first attempt at star trails. Light poluttion makes it tougher to get anything worthwhile. On top of that, clouds and airplanes peeked into the frame. In anycase, I learned a lot, so I am pleased with the results. I learned things I could do better and things that just require a more rural environment. I used the A6000, Rokinon 12mm, the Sony time lapse app and Photoshop to combine. Stay tuned... Next time... Any tips are welcome.
