Overview
For nearly 20 years QSI has been synonymous with high-quality desirable cameras for astronomers. Now in 2024 we proudly announce the 700 Series.
In two decades, much has changed beyond recognition. Sensors are now back-illuminated CMOS with native 16-bit digitisation. QE is an amazing 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 we have taken our best technology. Filterwheels are mechanically indexed to ensure the most precise location for 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.
Specifications
QSI 726
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.
