Featuring the latest technological advances, it offers exceptional performance thanks to its large CMOS sensor, advanced cooling and integrated features.<\/p>\n<h3>CMOS sensor and performance<\/h3>\n<p>The QSI 760 is equipped with Sony's IMX455 monochrome sensor, considered one of the best CMOS sensors for astrophotography. This full-frame sensor features the following characteristics:<\/p>\n<ul>\n<li><strong>Resolution<\/strong> 61 megapixels with a matrix of 9576 x 6380 pixels, offering outstanding image quality.<\/li>\n<li><strong>Pixel size<\/strong> 3.76 \u00b5m, ideal for capturing fine details while maintaining high sensitivity.<\/li>\n<li><strong>Sensor size<\/strong> 36 mm x 24 mm (43.3 mm diagonal), for complete coverage of large optical fields.<\/li>\n<li><strong>Quantum Efficiency (QE)<\/strong> Up to 90 %, for optimum conversion of light into digital signals.<\/li>\n<li><strong>Playback noise<\/strong> Only 1.2 electrons, ensuring extremely clean images even with long exposures.<\/li>\n<li><strong>Maximum potential well<\/strong> 51,000 electrons, offering an excellent dynamic range.<\/li>\n<\/ul>\n<p>The backlit sensor (BSI) effectively eliminates artifacts such as \"amp glow\" and banding, producing sharp, noise-free images.<\/p>\n<h3>Thermal cooling<\/h3>\n<p>The camera is equipped with a two-stage Peltier cooling system, capable of lowering the sensor temperature to 45\u00b0C below ambient. This advanced cooling minimizes thermal noise, essential for long astronomical exposures.<\/p>\n<ul>\n<li>The sensor chamber is hermetically sealed with a fused silica window featuring a double-sided anti-reflective coating, reducing light halos and preventing condensation.<\/li>\n<\/ul>\n<h3>Integrated filter wheels : Two options available<\/h3>\n<p>The QSI 760 is available with two configurations of motorized filter wheels:<\/p>\n<ol>\n<li><strong>5-position filter wheel<\/strong> :\n<ul>\n<li>Compatible with 2\" mounted or 50 mm unmounted filters.<\/li>\n<li>Ideal for a restricted set of filters (e.g. LRGB + H\u03b1).<\/li>\n<\/ul>\n<\/li>\n<li><strong>7-position filter wheel<\/strong> :\n<ul>\n<li>Compatible with unmounted 50 mm diameter filters.<\/li>\n<li>Designed to accommodate a wider range of filters, especially for narrow-band imaging (H\u03b1, OIII, SII).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p>These filter wheels minimize backfocus, making them easy to use with various optical accessories such as focal reducers.<\/p>\n<h3>Connectivity and Ergonomics<\/h3>\n<p>The QSI 760 is designed to be practical and ergonomic:<\/p>\n<ul>\n<li><strong>Simplified connectivity<\/strong> :\n<ul>\n<li>USB 3.0 port for fast data transfer.<\/li>\n<li>Two additional USB 2.0 ports enable direct connection of peripherals such as a guide camera.<\/li>\n<li>A threaded power outlet provides a secure connection for accessories.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Robust construction<\/strong> :\n<ul>\n<li>Made from durable, long-lasting materials.<\/li>\n<li>Supplied in a rigid molded case with protective foam for secure transport.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>Technical features<\/h3>\n<ul>\n<li>Extended dynamic range thanks to a native 16-bit analog-to-digital converter (ADC).<\/li>\n<li>Compatible with popular acquisition software via ASCOM drivers (Maxim DL, NINA, etc.).<\/li>\n<li>Rolling shutter with exposure range from 1 ms to 24 hours.<\/li>\n<\/ul>\n<h3>In the Box\" contents<\/h3>\n<p>The QSI 760 camera is supplied with the following accessories:<\/p>\n<ol>\n<li>QSI 760 camera (with integrated filter wheel - 5- or 7-position version depending on model selected).<\/li>\n<li>High-speed USB 3.0 cable.<\/li>\n<li>External power supply with threaded connectors.<\/li>\n<li>Windows-compatible acquisition software (downloadable).<\/li>\n<li>Detailed user manual.<\/li>\n<li>Rigid molded case with protective foam.<\/li>\n<\/ol>\n<h3>Conclusion<\/h3>\n<p>The QSI 760 camera boasts a high-performance full-frame sensor, advanced cooling and an ergonomic design tailored to the demanding needs of astrophotographers. Whether you choose the 5- or 7-position filter wheel version, it guarantees outstanding image quality and versatility for professional astronomical imaging.<\/p>","protected":false},"excerpt":{"rendered":"<p>La cam\u00e9ra QSI 760 La cam\u00e9ra QSI 760 est un mod\u00e8le phare de la s\u00e9rie QSI 700, sp\u00e9cialement con\u00e7ue pour l\u2019imagerie astronomique de haute pr\u00e9cision.
