Its peak Quantum Efficiency of 80% and low 4.0e read noise allow it to reliably detect faint guide stars, even in sparse fields. A 12-bit ADC and a maximum frame rate of 39 FPS ensure your mount receives corrections quickly and accurately, keeping your long exposures sharp.\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\u003eIMX225 Sensor: 80% QE and 4.0e Read Noise for Reliable Guiding\u003c\/h3\u003e\n\u003cp\u003eAt the core of the SV905C is the Sony IMX225 sensor, chosen for its high sensitivity and low noise characteristics. A peak QE of 80% means the camera makes efficient use of incoming light, enabling it to lock onto fainter guide stars than less sensitive cameras. This is critical when your target is in a star-poor region of the sky or when using an off-axis guider.\u003c\/p\u003e\n\u003cp\u003eThe camera's low read noise of 4.0e, combined with its HCG (High Conversion Gain) mode, preserves the signal-to-noise ratio even when you increase the gain. This results in cleaner guide star profiles and more stable guiding, as the software isn't chasing atmospheric scintillation or electronic noise.\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\u003eSmart Design: 8.5mm\/12.5mm Back Intercept and Repeatable Focusing\u003c\/h3\u003e\n\u003cp\u003eThe SV905C is built for practical use in the field. It features dual back intercept distances of 8.5mm and 12.5mm, providing the flexibility needed to achieve focus in various setups, from separate guide scopes to off-axis guiders with different prism-to-sensor distances. Its standard 1.25\" body fits directly into most guide scopes and focusers.\u003c\/p\u003e\n\u003cp\u003eFor imagers who use portable setups, the camera body includes a scale mark and snap ring. This simple but effective feature allows you to mark your focus position, ensuring you can return to perfect focus quickly night after night without guesswork. The modern Type-C USB 2.0 port provides a reliable connection to your control computer.\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\u003eBroad Compatibility: PHD2, ASCOM, and Multi-OS Support\u003c\/h3\u003e\n\u003cp\u003eA guide camera is only as good as its software support, and the SV905C offers wide-ranging compatibility.
