The purpose of these systems is to carry out All or Full Sky surveillance of the night or day sky, and in a continuous fashion. It is possible to assess, in real time, the night sky quality, and to record fast phenomena (meteors and fireballs) or slower (satellites, rockets, noctilucent clouds, zodiacal light, aurora, airglow ....).

Thanks to its high sensitivity, this system can record a very good image quality of the night sky, while producing images of stars that will not be trailed by natural Earth rotation, no star tracking is required.

This camera is a special product, that has been purchased by 4 units. The aim of this project is to cover full horizon line in high resolution fashion with 4 camera laid 90° each other. The field of view of each camera is 100° horizontal by 70° vertical. A special stand has been design to include a bit of horizon line in the image. The camera is similar to OMEA 8 with a different lens.

Focus and auto-iris remote control are included.
