The ASI294MC is an uncooled colour astronomy camera built around the Sony IMX294. Its 19.1 × 13 mm sensor records 4144 × 2822 pixels with 4.63 µm sampling.
Imaging performance
The manufacturer specifies a 14-bit ADC, 63,700-electron full well, 90% peak quantum efficiency and read noise of As low as 1.2 electrons. Capture speed is 19 fps at 12-bit; 16.3 fps at 14-bit. 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 6.5 mm bare; 17.5 mm with 11 mm ring sensor spacing. Its AR-coated window protects the sensor. The body is 62 mm in diameter and weighs 140 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.
