The ASI664MC is an uncooled colour astronomy camera built around the Sony IMX664AAQR1-C. Its 7.841 × 4.454 mm sensor records 2704 × 1536 pixels with 2.9 µm sampling.
Imaging performance
The manufacturer specifies a 12-bit ADC, 36,500-electron full well, 91% peak quantum efficiency and read noise of 0.46–5.8 (3.2 at 19 dB gain) electrons. Capture speed is 95 fps advertised maximum. Smaller regions of interest can increase frame rate; speed depends on ADC mode, output format, exposure and connection.
Applications
One-shot colour capture records colour during a single imaging sequence. High-speed video allows short exposures and frame selection for lunar and planetary 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.
