iOptron Camera iCam 464C (74122)

The iCAM464C camera features a Sony IMX464 color sensor, making it an excellent choice for planetary imaging. It has an imaging area of 1/1.8”, a pixel size of 2.9µm, and a resolution of 4.2MP (2712 x 1538), with a diagonal measurement of 9mm. This camera offers very high sensitivity and exceptionally low readout noise, achieving values as low as 0.75e at a gain of 350 and approximately 0.71e at a gain of 400.

The iCAM464C includes advanced features such as DPS (Dead Pixel Suppression) technology, which eliminates abnormal or dead pixels by analyzing dark frames, and HCG mode, which activates automatically when the gain is set to ≥80. HCG mode significantly reduces readout noise while maintaining high dynamic range at low gain settings. Its unique QE response peaks at 800-850nm, making it ideal for infrared imaging when paired with an IR850 or CH4 filter.

When connected via USB3.0, the camera achieves up to 93 FPS in RAW8 mode (10-bit ADC) during full-resolution preview. To maximize USB3.0 data speeds during image recording, it is recommended to use a high-quality solid-state drive. The ST-4 guiding port allows easy connection to a mount GUIDE port for autoguiding.
