QSI 726 Mono CMOS Imaging Camera

For nearly 20 years, QSI has been synonymous with high-quality, desirable cameras for astronomers. Now, in 2024, they proudly announce their 700 Series.

The QSI 726 features Sony's high-resolution Mono IMX571 CMOS Sensor, which provides outstanding image quality, resolution, and sensitivity.

In two decades, much has changed beyond recognition. Sensors are now back-illuminated CMOS with native 16-bit digitisation. QE is an impressive 90%, and readout is a speedy 120 million pixels per second over USB3, a performance that once was unimaginable. What is maintained by QSI’s newest cameras is the integrated design, attention to detail, and bulletproof reliability. In the design of the 700 series, QSI has taken their best technology. Filterwheels are mechanically indexed to ensure the most precise locations and perfect flat fields. The fused silica window is dew-resistant and is coated on both sides with high transmission anti-reflective coating to minimise halos. The cameras use a highly efficient 2-stage Peltier cooler that draws less current and delivers more cooling than some other cameras.

The QSI 726 is the optimum camera for most amateur telescopes. The 28mm diagonal IMX571 maximises the sharpest parts of a telescope’s image and is less affected by coma and vignetting than larger sensors. As with its bigger brother, the 760, cable clutter is reduced thanks to the integrated filter wheel (36mm), 2 USB2 in sockets and power out. Power sockets have threaded connections for maximum reliability. 

QSI cameras are designed in Norwich, UK, by a dedicated team with many years of experience in astronomy. Skills include 10-layer high-speed PCB design and platform-independent software code base. The cameras are manufactured in a state-of-the-art facility in Lisbon, PT. Quality is controlled using an ISO9001:2015 accredited management system. The factory extensively uses solar power and takes seriously the potential impact of manufacturing on the environment, gaining ISO 14001 accreditation.
