Launch Imaging AssistantThe Player One Mars-M IMX290 Mono Planetary Camera combines a 2.1 Megapixel Sony IMX290 sensor with 2.9µm pixels, a combination purpose-built for high-resolution lunar and planetary imaging. It achieves a maximum frame rate of 136 FPS at full resolution, while its high-sensitivity design reaches a peak QE of approximately 80% with read noise as low as 0.98e. The 1/2.8" CMOS sensor features a 6.5mm diagonal and a full well capacity of 14.6k e, captured through a 12-bit ADC for smooth tonal gradations on bright targets like Jupiter and Saturn.
At the core of the Mars-M is the monochrome Sony IMX290 sensor, prized for its high sensitivity and extremely low read noise. Its 2.9µm pixels create a sharp image scale on long focal length Schmidt-Cassegrains and Maksutovs, resolving fine detail in cloud bands and crater rims without requiring aggressive Barlow lenses. As a monochrome camera, it captures significantly more light than its color counterparts, resulting in brighter, higher-contrast images that are essential for lucky imaging.
With a peak Quantum Efficiency of ≈80% and read noise that drops to just 0.98e, the Mars-M extracts faint details with minimal noise, even during very short exposures. While its 6.5mm diagonal sensor is optimized for planets, the Moon, and sunspots, its primary trade-off is a smaller field of view, making it less suited for capturing large nebulae or galaxies in a single frame.
The Mars-M can stream full-resolution 1944×1096 video at up to 136 FPS in 10-bit mode. This high frame rate is critical for freezing moments of atmospheric stability, allowing you to select only the sharpest frames for stacking. To ensure every one of those frames is captured without corruption, Player One includes an onboard DDR3 cache.
This cache acts as a high-speed buffer, preventing dropped frames that can occur when the host computer's hard drive cannot keep up. It stabilizes data transmission, reduces read noise, and lowers the computational demand on your PC. This makes high-speed capture reliable even on older laptops or when using a USB 2.0 connection.
The Mars-M incorporates several features to ensure clean, high-contrast images. Dead Pixel Suppression (DPS) is an onboard technology that analyzes dark frames to map and correct for hot or cold pixels automatically. This correction happens inside the camera before the data is sent to your computer, saving you a post-processing step.
The sensor is protected by a D21*1.1MM window with a multi-layer anti-reflection coating (AR Plus), maximizing light transmission and preventing internal reflections. For solar imagers, an adjustable focal plate helps mitigate Newton's rings, a common frustration when imaging through narrowband solar telescopes.
Both the Mars-M and ZWO's popular ASI290MM camera are built around the same excellent Sony IMX290 monochrome sensor, giving them nearly identical resolution, pixel size, and quantum efficiency. The primary differences lie in the features Player One has engineered around the sensor.
A monochrome sensor is significantly more sensitive than a color sensor because every pixel is used to detect light, rather than being filtered for red, green, or blue. This results in brighter, sharper, and higher-contrast images of the Moon and planets. For color imaging, you can use a separate filter wheel to create superior LRGB composites.
The DDR3 cache acts as a buffer to prevent data loss during high-speed video capture. When you're recording at 136 FPS, your computer's hard drive can sometimes lag, causing "dropped frames." The cache stores the data temporarily, ensuring a smooth and stable transfer, so you never lose critical data during a moment of perfect seeing.
Yes. The Player One Mars-M is equipped with a standard ST4 guide port. Its high sensitivity and low read noise make it an excellent autoguider for deep-sky imaging when you are not using it for planetary work.
The 2.9µm pixels of the Mars-M are an excellent match for a typical 8" f/10 SCT, providing a well-sampled image scale for Jupiter's cloud bands and Great Red Spot. At this focal length, you can capture detailed video at high frame rates (over 60 FPS) to "freeze" atmospheric turbulence, allowing software like AutoStakkert! to produce a sharp final image.
Absolutely. The Mars-M's monochrome sensor is highly sensitive to the H-alpha wavelength used in most dedicated solar telescopes. Its high frame rate is ideal for capturing sharp detail in active regions and prominences. The camera also features an adjustable focal plate to help reduce Newton's rings, a common artifact in solar imaging.
DPS is a built-in feature that automatically identifies and corrects for defective pixels on the sensor. It analyzes dark frames to create a map of these pixels and then replaces their values with an average of the surrounding pixels during imaging. This provides a cleaner image straight from the camera, reducing the need for manual cosmetic correction in software.
