However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. Pettit described his technique as follows: 'My star trail images are made by taking a time exposure of about 10 to 15 minutes. This avoids possible heat build up or digital noise caused from a single long exposure.Īmerican astronaut Don Pettit recorded star trails with a digital camera from the International Space Station in Earth orbit between April and June, 2012. However, this can be avoided through the use of shorter exposure times that are then stacked in post production software. Another problem that digital cameras encounter is an increase in electronic noise with increasing exposure time. On these cameras, the Bulb, or B, exposure setting keeps the shutter open. Mechanical cameras that do not require a battery to open and close the shutter have an advantage over more modern film and digital cameras that rely on battery power. The star trails captured with 136 minutes long period of exposure in Eleebana, NSW, Australia on Mar 03, 2019īecause exposure times for star trail photographs can be several hours long, camera batteries can be easily depleted. Wide-apertures, such as f/5.6 and f/4, are recommended for star trails.

Even though star trail pictures are created under low-light conditions, long exposure times allow fast films, such as ISO 200 and ISO 400. Typical exposure times range from 15 minutes to many hours long, depending on the desired length of the star trail arcs for the image. A cable release or intervalometer allows the photographer to hold the shutter open for the desired amount of time. Photographers generally make these images by using a DSLR or Mirrorless camera with its lens focus set to infinity. Star trails are considered relatively easy for amateur astrophotographers to create. Star trail photographs are captured by placing a camera on a tripod, pointing the lens toward the night sky, and allowing the shutter to stay open for a long period of time.
