QSI 760-W7 - Full Frame IMX455 61mp Monochrome CMOS Camera with Integrated 7 Position 50mm Filter Wheel

The new QSI 700 series features the best CMOS sensors, high quality electronics, an integrated design and European manufacture!

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 digitization. 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. Filter wheels 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 minimize halos. The cameras use a highly efficient 2-stage Peltier cooler that draws less current and delivers more cooling than some other cameras.

QSI 700 Series

The new QSI 700 Series cameras are the company's latest high-end mono astroimaging cameras and include the QSI 760 and QSI 726.

The new QSI 700 Series cameras offer CMOS sensors that are back-illuminated with native 16-bit digitization. QE is 90% and readout is a fast 120 million pixels per second over USB3. The cameras offer built in 2" filter wheels are mechanically indexed to ensure the most precise location for perfect flat fields. The fused silica windows are dew resistant and coated on both sides with high transmission anti-reflective coating to minimize halos. The cameras use a highly efficient 2-stage Peltier cooler that draws less current and delivers more cooling.

QSI 760

The full frame QSI 760 is the flagship product of the new QSI 700 Series cameras. The full frame IMX455 is widely regarded as the premium sensor for astronomers. The integrated 2"/50mm filter wheel minimizes back focus, essential for the widest compatibility with focal reducers. Cable clutter is reduced thanks to the integrated filter wheel, 2 USB2 in sockets and power out. Power sockets have threaded connections for maximum reliability.

QSI 726

The QSI 726 is the optimum camera for most amateur telescopes. The 28mm diagonal IMX571 maximizes 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.
