iOptron iCAM464C Planetary Camera

Sony IMX464: 4.2MP Resolution at 93 FPS

At the heart of the iCAM464C is the 1/1.8" Sony IMX464 sensor, which provides a 2712 x 1538 pixel array. This 4.2MP resolution gives you a larger field of view than typical 2MP planetary cameras, making it easier to frame Jupiter with its Galilean moons or capture expansive lunar landscapes without creating large mosaics. The high-speed readout achieves 93 fps at full resolution, enabling the "lucky imaging" technique required to overcome atmospheric turbulence and produce sharp, detailed final images.

Low-Noise Architecture: 0.7e Read Noise and HCG Mode for High-Dynamic-Range Imaging

The iCAM464C is engineered for high signal-to-noise performance. Its ability to achieve read noise as low as 0.7e ensures that faint, low-contrast details are not lost in the electronic background. The camera also supports HCG (High Conversion Gain) mode, which automatically activates at higher gain settings to reduce read noise without compromising the dynamic range provided by the 12K e full well depth. This combination is critical for capturing both the bright zones and subtle belt structures on planets in a single exposure stack. The camera's rolling shutter is well-suited for planetary work, where exposure times are typically very short.

Guiding and Connectivity: Integrated ST-4 Port and USB 3.0 Data Transfer

Beyond its primary role as a planetary imager, the iCAM464C serves as a highly capable autoguider for deep-sky astrophotography. The integrated ST-4 compatible guide port provides a universal connection to most equatorial mounts for precise tracking corrections. To handle the massive amount of data generated at 93 fps, the camera features a USB 3.0 port, ensuring a stable, high-speed connection to your capture PC. The camera connects to your telescope via a standard 1.25" adapter, making it compatible with nearly any setup.

iCAM464C vs. IMX462-Based Cameras: 4.2MP vs. 2.1MP

Cameras using the Sony IMX462 sensor are renowned for their exceptional sensitivity, particularly in the near-infrared spectrum. They represent a strong choice for methane-band imaging or capturing details on the dimmest targets. The primary advantage of the iCAM464C is its resolution. With 4.2MP, it doubles the pixel count of 2.1MP IMX462-based cameras, offering several key benefits:

• Larger Field of View: You can capture a wider area of the sky, which is ideal for mosaics of the Moon or Sun (with a certified solar filter).
• More Pixels on Target: For a given telescope, the iCAM464C places more pixels on a planet's disk, allowing for greater image scale and more detailed processing.
• Framing Flexibility: The larger canvas makes it easier to keep a planet centered during a capture run, especially in conditions of imperfect tracking.

The choice depends on your priority. For maximum resolution and field of view, the iCAM464C is the clear winner. For specialized imaging that requires the highest possible sensitivity, an IMX462-based camera may be preferred.
