Star Trails

We are in a night photography course and wanted to photograph star trails. Unfortunately, we live in an area with extreme light pollution. In addition, it is often cloudy and rainy. As an experiment, we build a box with a plexiglass lid and a black interior to house our camera. The box kept water off the camera and served as a “lens hood.” We sealed the box with silicone and mounted it to an open area at our roofline.

The first night we tried to use the box, a heavy dew fell and coated the plexiglass blurring our photos. We used a silicone spray on the plexiglass to keep waterdrops from sticking and tried again the next night. Here is our result.

Given the odds against us, we were pretty happy with this photo. A few clouds and the light of the full moon affected the photo but we think we can apply this technique later this year in a moonless and cloudless sky.
