  • The mount described here provides one of the easiest ways to track the night sky with your camera. Known generically as a barn-door tracking platform, it’s easy to make and works well for camera-and-lens astrophotography. I built the tracker shown here based on one recently made by Ohio telescope maker Ed Jones and on a platform built by Sky & Telescope’s Dennis di Cicco in the mid-1980s. Ed and Dennis used parts they had lying around, but I used components sourced online and from local hardware stores.
