Deep-sky cameras are designed for long exposures on large deep-sky objects such as star clusters, nebulas or galaxies.
Typical deep-sky cameras have larger sensors to handle the wide fields of view required. They may also have larger pixel sizes for additional sensitivity as well as allowing for a greater field of view.
Because they are intended for long exposures, deep sky cameras have cooling systems incorporated in them. This decreases the amount of noise resulting from the electronic circuitry inside the camera.
The ATR3CMOS Series is designed with an integrated heat dissipation structure and an efficient cooling module. This allows the image sensor to operate at a temperature that is 45 degrees lower than the ambient temperature.
The USB 3.0 interface offers a 5Gbps bandwidth. A 512MB DDR3 buffer guarantees stable data transmission, preventing frame loss. Together these features make sure that camera can work with a PC that has a modest hardware configuration.
