The Camera Obscura

Invented centuries ago as an aid for artists, the camera obscura brings the outside inside. From its humble beginnings as a pinhole camera, the modern device can be a fully adjustable instrument that reveals insects around a nearby streetlight, traffic on distant freeways or smoke from the wheels of landing aircraft. The image is projected as a moving, full-color display viewed by a group of people in a darkened room.

The camera obscura appeals to observers of all ages and interest – landscape views, clouds, sunsets, moon, sun and planets – all are revealed while you remain comfortably seated inside your own motorized telescope
