Cameras, CCD and CMOS sensors

CMOS sensor-based astro cameras have recently come to the fore and have really changed the game in amateur as well as professional astronomy. The cameras used in the images from New Jersey on this site are the ZWO ASI2400MC, ASI071MC and the ASI2600MM. The images taken remotely from Chile before 2024 used cameras with CCD sensors, the KAF-16803 CCD full frame sensor in FLI and SBIG configurations. Since 2024 we are using the Moravian C5A 100M CMOS camera (mono camera with LRGB filters).
