With multiple readout modes offering noise as low as 1.1e- and a full well capacity exceeding 80ke-, this camera captures both the faintest nebulosity and brightest stellar cores in a single exposure. Data integrity is ensured by a 2GB DDR3 buffer and dual 2x10Gigabit Fiber interfaces, enabling a full-resolution 16-bit frame rate of up to 3.5 FPS for demanding research applications.\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\u003eFull-Frame 61.17MP Sony IMX455 Sensor: Native 16-Bit Depth\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the QHY600C Pro is the 36mm x 24mm Sony IMX455 sensor, which provides an enormous 9576 x 6388 pixel array. The 3.76µm pixels are an ideal match for high-resolution refractors and corrected reflectors, sampling the sky with immense detail. Unlike cameras that use 12-bit or 14-bit conversion, the QHY600 Pro employs a true, native 16-bit A\/D converter, rendering 65,535 distinct grayscale levels for exceptionally smooth tonal gradations in deep-sky objects.\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\u003eMulti-Mode Readout: 1.1e- Read Noise and \u0026gt;80ke- Full Well\u003c\/h3\u003e\n\u003cp\u003eThe QHY600C Pro offers several selectable readout modes to optimize the camera for any target. In High Gain Mode, read noise plummets to a mere 1.1e-, allowing you to extract faint signal from photon-starved regions with minimal noise penalty. For bright targets or long-exposure narrowband imaging, the Extended Full Well Mode expands pixel capacity to over 80ke-, preventing saturated stars and preserving highlight detail. This flexibility, combined with a dark current of just 0.0022e-\/pixel\/sec at -20°C and zero amplifier glow, ensures a clean, data-rich foundation for your 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\u003eProfessional I\/O: 2x10Gbit Fiber, USB3.0, and a 2GB DDR3 Buffer\u003c\/h3\u003e\n\u003cp\u003eDesigned for applications where speed and reliability are critical, the QHY600C Pro includes both a standard USB3.0 port and a dual 10Gigabit Fiber Optic interface. The fiber connection allows for high-speed data transfer over long distances, delivering up to 3.5 FPS at full 16-bit resolution. To handle this massive data stream without dropped frames, the camera incorporates a 2GB DDR3 memory buffer, a feature essential for remote observatories and automated scientific surveys.\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\u003eRegulated Cooling to -35°C Below Ambient\u003c\/h3\u003e\n\u003cp\u003eThermal noise is suppressed by a powerful dual-stage thermoelectric cooling system, capable of achieving a regulated temperature typically -35°C below ambient for long exposures.
