Its back-illuminated architecture features 2.9μm pixels and a peak Quantum Efficiency of approximately 91%, capturing faint details with readout noise as low as 0.7e. A deep 38ke full well capacity, processed through a 12-bit ADC and supported by a 128M buffer, ensures high dynamic range and stable frame capture at up to 24 FPS over its USB 2.0 connection.\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 IMX662 Sensor: 2.1 MP at 2.9µm for High-Resolution Planetary Work\u003c\/h3\u003e\n\u003cp\u003eThe SV305C is built for capturing fine details on solar system targets. The sensor's 2.9µm pixels are well-matched to the resolving power of many Schmidt-Cassegrains and Maksutovs, allowing you to sample atmospheric details on Jupiter or subtle rilles on the Moon without needing an aggressive Barlow lens. With a peak QE of 91%, the camera makes efficient use of every photon, which is critical for pulling out low-contrast features during short video 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\u003e38ke Full Well and HCG Mode for High Dynamic Range\u003c\/h3\u003e\n\u003cp\u003eA key challenge in planetary imaging is capturing the bright planetary disk without blowing out the highlights on its moons or cloud features. The SV305C's 38ke full well capacity provides the headroom to manage this contrast. This is complemented by the camera's HCG (High Conversion Gain) mode, which automatically engages at higher gain settings to reduce read noise to just 0.7e while preserving the sensor's full dynamic range, resulting in cleaner 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\u003e128MB Buffer and Dual 7.5mm\/12.5mm Back Focus\u003c\/h3\u003e\n\u003cp\u003eWhile the SV305C uses a USB 2.0 interface, it incorporates a 128MB DDR buffer to ensure your imaging sessions are free from dropped frames. The buffer caches image data, feeding it to the computer reliably even if the USB bus is momentarily interrupted. For physical integration into your optical train, the camera offers two back focus distances—7.5mm and 12.5mm—providing critical spacing flexibility for use with filter wheels, off-axis guiders, or other accessories.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in UV\/IR Cut Filter:\u003c\/strong\u003e The protective window over the sensor blocks ultraviolet and infrared wavelengths, ensuring accurate color balance for one-shot-color imaging without requiring a separate filter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Platform Support:\u003c\/strong\u003e The camera is compatible with Windows, Linux, Raspberry Pi, Mac OS, and Chrome OS, offering broad support for various capture software and operating environments.\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\u003eSV305C (IMX662) vs. IMX462-Based Cameras: A Generational Leap\u003c\/h3\u003e\n\u003cp\u003eThe IMX662 sensor in the SV305C represents a significant upgrade over the previous-generation IMX462.
