Astrocam
The Astrocam 110 (or Astrocam) is a model rocket with a built-in camera for taking aerial photographs. The Astrocam was introduced in the 1979 Catalog by its manufacturer Estes and it can be flown with B6-4 and C6-7 model rocket motors (see Model rocket motor classification). The Astrocam was available as kit, or as ready-to-fly model. Both versions use the Estes Delta II launch body. The camera uses 110 film and is mounted in the nose cone of the rocket with the aperture perpendicular to the main axis of the rocket. A mirror held in a hood is used like a periscope to enable the camera to look forward. The camera needs to be manually advanced and "cocked" by pulling a string attached to spring-loaded shutter taut. When the nose cone is placed on the rocket body, the string is placed between the nose cone and the body so that when the ejection charge of the engine expels the nose cone, the string is released causing one frame of film to be exposed. Since the rocket is not steerable, the photographer can not determine what the camera will photograph. Stock models of the Astrocam were intended to take their photographs
