Its small 2.0µm pixels are optimized for capturing fine detail on the planets, while the back-illuminated architecture and low 0.57e- read noise ensure clean captures of faint targets. A generous 512MB DDR3 buffer sustains a full-frame capture rate of 43 FPS without dropping frames, making it a powerful tool for lucky imaging of the Moon, Sun, and planets.\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\u003eSony IMX678 Sensor: 8.4MP Resolution and 2.0µm Pixels\u003c\/h3\u003e\n\u003cp\u003eAt the core of the QHY5III678C is Sony's back-illuminated IMX678 sensor, which delivers an 8.4 megapixel image over a 3856 x 2180 array. The small 2.0µm pixels provide excellent image sampling on a wide range of telescopes, allowing you to resolve fine details in Jupiter's cloud bands or delicate lunar rilles. The sensor's low read noise, ranging from just 0.57e- to 3.3e-, combined with a 9ke- full well capacity gives clean, well-exposed planetary frames.\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\u003eHigh-Speed Capture: 43 FPS at 8-bit with a 512MB DDR3 Buffer\u003c\/h3\u003e\n\u003cp\u003ePlanetary imaging relies on capturing thousands of frames in a short window to freeze atmospheric turbulence. The QHY5III678C is built for this task, streaming full 8.4MP frames at 43 FPS in 8-bit mode. The onboard 512MB DDR3 image buffer is critical, preventing data bottlenecks and dropped frames that can ruin a capture session.\u003c\/p\u003e\n\u003cp\u003eFor even higher frame rates, you can use a Region of Interest (ROI) to focus only on the planet. This boosts speeds dramatically, reaching 85 FPS for a 1080-line window and up to 140 FPS for a 640-line window, ensuring you capture those fleeting moments of perfect seeing.\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\u003eEnhanced NIR Sensitivity with IR-Cut and IR-850nm Filters\u003c\/h3\u003e\n\u003cp\u003eThe IMX678 sensor features deeper photodiodes, giving it exceptional sensitivity in near-infrared (NIR) wavelengths. While this color camera includes a built-in IR-cut filter to ensure correct visual-spectrum color balance for planets like Jupiter, QHY also includes an IR850 filter in the box.
