ASI183MM Pro

The ZWO ASI183MM Pro is a cooled monochrome astronomy camera featuring a 20.1-megapixel Sony IMX183 back-illuminated CMOS sensor with 5496x3672 resolution and 2.4-micron pixel size, ideal for capturing high-resolution images of deep-sky objects such as nebulae, supernova remnants, and galaxies, lunar and solar images, and real-time electronically-assisted astronomy (EAA). Integrated TEC cooling reduces sensor temperature to 40-45°C below ambient to enable low-noise imaging, with fast USB3.0 transfer at up to 19 fps at maximum resolution and a 256MB DDR3 buffer for quick and stable data transfer. The back-illuminated sensor provides a peak quantum efficiency of 84%, and the full well capacity of the 2.4 micron pixels is 15,000e with read noise of 1.6e at 30dB gain. The compact red anodized CNC aluminum body measures 78mm in diameter and weighs only 410g.
