Player One Mars-C II IMX662 Color Planetary Camera

The IMX662 Sensor: 2.1 MP at 108 FPS

At the heart of the Mars-C II is the Sony IMX662, a 1/2.8" format color sensor that delivers a 1936x1100 resolution image. This sensor size is an excellent match for the corrected image circle of most Barlow lenses and Schmidt-Cassegrains, minimizing field curvature issues. The camera's ability to stream 12-bit data at 108 FPS allows you to leverage lucky imaging techniques, capturing thousands of frames in a short period to freeze moments of steady atmospheric seeing and resolve intricate details in the cloud bands of Jupiter or the Cassini Division in Saturn's rings.

Zero Amp Glow and a 54k e- Full Well

A standout feature of the Mars-C II is its complete lack of amplifier glow. Unlike many CMOS sensors that produce a bright pattern on dark frames, the IMX662's background is entirely dark, even when stretched. This produces a perfectly clean foundation for your images, simplifying processing and making the camera highly effective for EAA where live stacking benefits from a uniform background.

The sensor's deep 54k e- full well capacity provides immense dynamic range. This prevents brighter planetary features, like Mars' polar caps or Jupiter's Galilean moons, from saturating while you expose for fainter details, resulting in richer color and more nuanced images in a single capture session.

Onboard Hardware: DDR3 Cache and Dead Pixel Suppression (DPS)

Player One integrates a DDR3 cache into the Mars-C II to ensure stable, drop-free data transmission. This buffer protects your imaging session from lost frames, a common issue during high-speed capture, and reduces the demand on your computer's CPU. The camera maintains reliable performance even when connected to a USB 2.0 port.

The camera also features onboard Dead Pixel Suppression (DPS) technology. It analyzes the sensor and maps any abnormal pixels, automatically correcting them in each frame you capture. This saves significant time in post-processing by delivering cleaner raw data from the start.

Mars-C II (IMX662) vs. IMX462 Cameras: A 4x Full Well Advantage

While cameras based on the previous-generation IMX462 sensor are noted for their high infrared sensitivity, the Mars-C II with the IMX662 offers a decisive advantage for mainstream color planetary imaging. The primary difference is dynamic range.

• IMX462 Full Well: Typically around 13k e-.
• Mars-C II (IMX662) Full Well: A massive 54k e-, over four times greater.

This larger capacity means the Mars-C II is far less likely to saturate bright targets. You can use higher gain settings to capture faint moons or surface details without blowing out the highlights on the planet itself, yielding a more balanced and data-rich final image.
