The ASI678MC is an uncooled colour astronomy camera built around the Sony IMX678. Its 7.7 × 4.3 mm sensor records 3840 × 2160 pixels with 2 µm sampling.
The manufacturer specifies a 12-bit ADC, 11,270-electron full well, 83% peak quantum efficiency and read noise of As low as 0.6 electrons. Capture speed is 47.5 fps advertised maximum. Smaller regions of interest can increase frame rate; speed depends on ADC mode, output format, exposure and connection.
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.
The USB connection supplies power and transfers images. The camera uses a M42 × 0.75 interface, with 12.5 mm sensor spacing. Its AR-coated protective 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.
