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 after the rocket had begun to descend after reaching apogee. However, in the Winter 1993 issue of the Estes Educator News magazine, two sets of instructions (Lookdown Astrocam, and the Lookdown Astrocam MK11) were included describing how the camera could be converted to look back down the length of the rocket before reaching apogee, or upon a staging event. Estes catalogs showed some of the photographs from these modified rockets, but they never produced a version designed to look down, or capable of being switched at will. A version of the Astrocam called the Astrocam 110 is also available, and the Estes Snapshot is very similar as well

A modern version of the Astrocam is the Oracle (rocket), Oracle, which shoots video. A newer video version, called the Astrovision, is also available.
