The QSI 760 camera

The QSI 760 is a flagship model in the QSI 700 series, specially designed for high-precision astronomical imaging. Featuring the latest technological advances, it offers exceptional performance thanks to its large CMOS sensor, advanced cooling and integrated features.

CMOS sensor and performance

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:

  • Resolution 61 megapixels with a matrix of 9576 x 6380 pixels, offering outstanding image quality.
  • Pixel size 3.76 µm, ideal for capturing fine details while maintaining high sensitivity.
  • Sensor size 36 mm x 24 mm (43.3 mm diagonal), for complete coverage of large optical fields.
  • Quantum Efficiency (QE) Up to 90 %, for optimum conversion of light into digital signals.
  • Playback noise Only 1.2 electrons, ensuring extremely clean images even with long exposures.
  • Maximum potential well 51,000 electrons, offering an excellent dynamic range.

The backlit sensor (BSI) effectively eliminates artifacts such as "amp glow" and banding, producing sharp, noise-free images.

Thermal cooling

The camera is equipped with a two-stage Peltier cooling system, capable of lowering the sensor temperature to 45°C below ambient. This advanced cooling minimizes thermal noise, essential for long astronomical exposures.

  • The sensor chamber is hermetically sealed with a fused silica window featuring a double-sided anti-reflective coating, reducing light halos and preventing condensation.

Integrated filter wheels : Two options available

The QSI 760 is available with two configurations of motorized filter wheels:

  1. 5-position filter wheel :
    • Compatible with 2" mounted or 50 mm unmounted filters.
    • Ideal for a restricted set of filters (e.g. LRGB + Hα).
  2. 7-position filter wheel :
    • Compatible with unmounted 50 mm diameter filters.
    • Designed to accommodate a wider range of filters, especially for narrow-band imaging (Hα, OIII, SII).

These filter wheels minimize backfocus, making them easy to use with various optical accessories such as focal reducers.

Connectivity and Ergonomics

The QSI 760 is designed to be practical and ergonomic:

  • Simplified connectivity :
    • USB 3.0 port for fast data transfer.
    • Two additional USB 2.0 ports enable direct connection of peripherals such as a guide camera.
    • A threaded power outlet provides a secure connection for accessories.
  • Robust construction :
    • Made from durable, long-lasting materials.
    • Supplied in a rigid molded case with protective foam for secure transport.

Technical features

  • Extended dynamic range thanks to a native 16-bit analog-to-digital converter (ADC).
  • Compatible with popular acquisition software via ASCOM drivers (Maxim DL, NINA, etc.).
  • Rolling shutter with exposure range from 1 ms to 24 hours.

In the Box" contents

The QSI 760 camera is supplied with the following accessories:

  1. QSI 760 camera (with integrated filter wheel - 5- or 7-position version depending on model selected).
  2. High-speed USB 3.0 cable.
  3. External power supply with threaded connectors.
  4. Windows-compatible acquisition software (downloadable).
  5. Detailed user manual.
  6. Rigid molded case with protective foam.

Conclusion

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.
