The ASI662MM is an uncooled monochrome astronomy camera built around the Sony IMX662. Its 5.568 × 3.132 mm sensor records 1920 × 1080 pixels with 2.9 µm sampling.
Imaging performance
The manufacturer specifies a 12-bit ADC, 38,200-electron full well, 91% peak quantum efficiency and read noise of 0.8–6.9 (1.22 at 19 dB gain) electrons. Capture speed is 107.6 fps advertised maximum. Smaller regions of interest can increase frame rate; speed depends on ADC mode, output format, exposure and connection.
Applications
Monochrome capture supports luminance and filtered imaging. Use suitable external filters to select the wavelength range for lunar, planetary or specialist imaging.
Connections and spacing
The USB connection supplies power and transfers images. The camera uses a M42 × 0.75 interface, with 12.5 mm sensor spacing. Its 21 × 1.1 mm AR-coated window protects the sensor. The body is 62 mm in diameter and weighs 126 g. Match optical adapters and any external filter to the required telescope spacing.
Use the exact named-model manufacturer connection and operating instructions linked with this product. Optional parts and adapters require their specified spacing and power limits.
