QHYCCD QHY600 Professional Color CMOS Camera

QHY's QHY600 CMOS color camera is a great, full frame astrophotography camera with extremely low dark and read noise. This professional version of the QHY600 uses the Sony IMX455 back-illuminated, full frame sensor with 3.76um pixels, measuring at 36mm x 24mm. A back-illuminated CMOS structure gives this camera improved full well capacity. Unbinned, the camera has a full well capacity of more than 51ke-. Binned 2x2 to 7.5um, the camera's full well is 196ke-, and binned 3x3 to 11um, the full well is 441ke-. This CMOS camera also has an extremely low dark current.

The monochrome QHY600 Professional camera comes with a plethora of features. These include a 2GB Image Buffer for smooth, uninterrupted, and high-speed data transfer and USB3.0 and 10 Gigbit Fiber port support high speed interface. Additionally, the professional version's support of 2x10 Gigabit Optical fiber ports provides faster interface, is very stable, and has a long transfer distance of up to 300 meters. The round camera design of this camera makes it ideal for the new generation of RASA telescopes because it can match the image field.

Equipped with an electronic rolling shutter, the camera utilizes Sony's Exmor BSI CMOS technology and electric shutter. This type of shutter is more reliable than a mechanical shutter and more stable when the astrophotographer takes a large number of exposures.

With a native 16-bit A/D on-chip, this camera has an output of 65536 levels, meaning that the camera gives a higher resolution and a system gain that is less than 1e-/ADU. QHY's 600 series cameras has no sample error noise and very low read noise. The QHY600 has only one electron of read noise, meaning the camera can achieve an SNR>3 at only four to six photons. You can use this camera for short exposures, narrow band imaging, sky surveys, time domain astronomy, fluorescence imaging, DNA sequencing, and microscopy!
