Its 2.9µm pixels and 2.1MP resolution capture fine details on Jupiter and Mars, while the staggering 136.1 FPS frame rate freezes moments of perfect seeing. With a peak Quantum Efficiency of approximately 89% and unmatched sensitivity in the near-infrared, this camera excels at cutting through atmospheric turbulence for remarkably sharp lunar, solar, and planetary captures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUnrivaled Near-Infrared (NIR) Sensitivity at 800nm+\u003c\/h3\u003e\n\u003cp\u003eThe core strength of the ASI462MM is the Sony IMX462 sensor's extraordinary sensitivity in the near-infrared spectrum. Where other planetary cameras see their response drop off sharply, the ASI462MM maintains high efficiency beyond 800nm. This allows you to leverage methane and other long-pass filters to reveal deep atmospheric features on Jupiter and Saturn that are invisible in the visible spectrum, effectively calming atmospheric seeing for sharper final images.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e136.1 FPS Capture Rate with Zero Amp Glow\u003c\/h3\u003e\n\u003cp\u003eAt a full resolution of 1936x1096, the ASI462MM streams data at up to 136.1 frames per second via its USB 3.0 interface. This high-speed capability is critical for \"lucky imaging,\" allowing you to capture thousands of frames in a short period to overcome atmospheric distortion. The integrated 256MB DDR3 buffer ensures stable, drop-free data transfer, while the sensor architecture eliminates amp glow entirely, even on longer exposures when using the camera for guiding.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed Mode:\u003c\/strong\u003e Captures full-resolution frames at 136.1 fps with a 10-bit ADC for maximum frame rate.\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Dynamic-Range Mode:\u003c\/strong\u003e Utilizes the full 12-bit ADC at 63.9 fps for smoother tonal gradations and a full well capacity of 11.2ke-.\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUltra-Low Read Noise of 0.47e- for Cleaner Stacks\u003c\/h3\u003e\n\u003cp\u003eThe ASI462MM leverages STARVIS technology and an integrated High Conversion Gain (HCG) mode to achieve a minimum read noise of just 0.47 electrons.

Its high sensitivity and extremely low 0.47e- read noise allow it to detect faint guide stars easily. The 2.9µm pixel size provides high-resolution guiding for a wide range of guide scope focal lengths, and the standard ST4 port ensures compatibility with virtually any equatorial mount.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the optimal focal ratio for the ASI462MM for planetary imaging?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFor ideal planetary imaging that critically samples the image, a focal ratio between f\/14 and f\/20 is recommended with the ASI462MM's 2.9µm pixels.

This allows it to capture finer detail (higher resolution) and fainter signals, making it the preferred choice for advanced planetary imagers who use a separate filter wheel to create color images. The color version offers convenience but at the cost of some sensitivity and resolution.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDoes the ASI462MM suffer from amp glow?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo. The ZWO ASI462MM's sensor design and circuitry completely eliminate amplifier glow.
