The Atik 490EX is the highest resolution Atik camera to date, featuring the latest generation Sony EXview HAD CCD II technology with outstanding Quantum Efficiency, very low noise and excellent thermal management. With 9.13 megapixels, it is designed to effectively work with fast focal ratio lenses such as Hyperstar and Fastar, and its lightweight and slim profile ensures it does not strain the telescope's corrector plate. Its excellent sensitivity and the possibility of binning while maintaining high pixel counts makes it one of the best cameras for deep-sky astrophotography, with unrivaled flexibility. The camera features a regulated cooling system that offers stable image calibration and generates very low noise, with a straightforward 12V power requirement and low power consumption suitable for both observatory use and amateur applications.
