Its back-illuminated architecture and 3.76µm pixels capture vast, high-resolution fields of view with exceptional sensitivity. Native 16-bit A\/D conversion ensures smooth tonal gradations over an immense dynamic range, while read noise as low as 1.0e- preserves the faintest details in your signal. With a massive 44mm x 33mm imaging area, a 1GB DDR3 buffer, and dual-stage TEC cooling capable of reaching -35°C below ambient, the QHY461PH is engineered to replace and surpass the performance of legacy large-format CCD cameras.\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\u003eThe 102 MP Sony IMX461: A Medium Format BSI Sensor\u003c\/h3\u003e\n\u003cp\u003eAt the core of the QHY461PH is the Sony IMX461, a back-illuminated (BSI) CMOS sensor with an effective resolution of 11664 x 8748 pixels. This 102-megapixel array, combined with a 3.76µm pixel size, provides an ideal balance of resolution and sampling for modern high-quality refractors and reflectors. The medium format 44mm x 33mm sensor (55mm diagonal) allows you to frame enormous celestial targets in a single shot.\u003c\/p\u003e\n\u003cp\u003eThe BSI structure places the sensor's wiring below the photosensitive layer, maximizing the light-gathering area of each pixel for higher quantum efficiency across the visible spectrum. For imagers using larger telescopes, 2x2 binning creates 7.5µm effective pixels and still delivers a 25-megapixel image, offering enhanced sensitivity and higher full well capacity while maintaining a resolution far greater than previous-generation CCDs.\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\u003eNative 16-bit A\/D and Multiple Readout Modes\u003c\/h3\u003e\n\u003cp\u003eThe IMX461 sensor features on-chip, native 16-bit analog-to-digital conversion, capturing image data with 65,536 distinct grey levels. This high bit depth provides the sample resolution needed to record subtle variations in nebulosity and galaxy structure without posterization, a critical advantage over 12-bit or 14-bit sensors. This architecture, where each column of pixels has its own A\/D converter, also contributes to the camera's remarkably low read noise of 1e- to 3.7e-.\u003c\/p\u003e\n\u003cp\u003eThe QHY461PH offers multiple user-selectable readout modes to optimize performance for different targets. You can choose between Standard Mode with a 50ke- full well capacity, or Extended Full Well Mode, which boosts capacity to 80ke- for capturing bright stars in dense fields without saturation. These capacities increase dramatically with binning, reaching up to 720ke- in 3x3 Extended Mode, giving you immense flexibility for both broadband and narrowband imaging.\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\u003eAdvanced Noise Control: -35°C Cooling and 0.003e- Dark Current\u003c\/h3\u003e\n\u003cp\u003eA clean signal is paramount for deep-sky imaging, and the QHY461PH employs a multi-faceted approach to noise suppression. A powerful dual-stage thermoelectric cooling (TEC) system actively reduces the sensor temperature to -35°C below ambient for long exposures, drastically lowering thermal noise. This results in an exceptionally low dark current of just 0.003 e-\/pixel\/s at a sensor temperature of -20°C.\u003c\/p\u003e\n\u003cp\u003eQHYCCD's design completely eliminates amplifier glow, ensuring that no part of the frame is contaminated by this common source of calibration error. Furthermore, the camera incorporates proprietary technology to suppress time-variant thermal noise, a characteristic of some BSI sensors, resulting in cleaner, more consistent raw frames that stack beautifully.\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\u003e1GB DDR3 Buffer and USB 3.0 Data Path\u003c\/h3\u003e\n\u003cp\u003eManaging the massive 102-megapixel data stream requires a robust data path.

A desiccant tube is included in the box.\u003c\/p\u003e\n\u003cp\u003eFor remote operation, the camera features robust power management. It requires a stable 12V supply and has Under Voltage Lockout (UVLO) protection, which warns you if the voltage drops below 11V. You can also reboot the camera by simply cycling the 12V power, eliminating the need to physically reconnect the USB cable.
