ASI 533MM

Uncooled Entry Level Camera for Deep Space Photography

The ASI533MM adopts a Sony back-illuminated IMX533 sensor, which is a 1" square-frame sensor suitable for deep sky photography needs. It can be regarded as an upgrade of the ASI183 series. Not only does it retain the high-quality features of the ASI183, such as high QE and high frame rate, it also features no amp glow, readout noise as low as 1.0e, and pixel size of 3.76 μm. 

Zero Amp Glow

Traditional CMOS sensors can generate weak infrared light, which is equivalent to a light source during exposures. The ASI533MM Pro uses a no-glow circuitry to ensure best-quality images regardless of gain or exposure length.
