The QHY600 Mono Full Frame Cooled CMOS Camera uses the latest SONY IMX455 back-illuminated sensor, a full frame (35mm format) sensor with 3.76um pixels and native 16-bit A/D. This sensor is available in both monochrome and color versions. The sensor size is 36mm x 24mm. With the round body design, the QHY600 is an ideal camera to match the image circle of the new generation of RASA telescopes.

The new Sony sensor used in the QHY600 has native 16-bit A/D on-chip. The output is real 16 bit with 65536 levels. Compared to 12-bit and 14-bit A/D, a 16-bit A/D yields higher sample resolution and the system gain will be less than 1e-/ADU with no sample error noise and very low read noise. This leads to the possibility of images with superb dynamic range.

One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. Even unbinned, the QHY600 has a full well capacity of more than 51ke-. When binned 2×2 to 7.5um the full well is 196ke- and when binned 3×3 to 11um the full well is 441ke-

The QHY600 has only one electron of read noise at high gain / full resolution and a 4FPS readout speed. One electron of read noise means the camera can achieve a SNR>3dB at only 4 to 6 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc. This makes the sensor ideal for sky surveys, time domain astronomy, fluorescence imaging, DNA sequencing and microscopy.

In order to provide smooth uninterrupted data transfer of the entire 60MP sensor at high speed, the QHY600 has 2GB DDR3 image buffer. In addition the camera features a USB3.0 interface for transmission of data at high speed.

    I bought the QHY600 Mono PH version two months ago, so I have time for deeper tests. A the beginning I commission to manufacture connector between telescope and camera. I had also some problems INDI driver (but I fixed that problem). During last two month I had taken images of M31 , NGC7023 and many single frames of other objects with different camera settings. Advantages of camera:
    – read modes (allow to more flexible gain setting)
    – IMX455 K Grade sensor and 16-bit A/D
    – strong and well made camera design
    – good Linux support
    – some problem with video mode on Linux and INDI
    – during short exposition camera become hot quicker
    I had earlier following QHY cameras: QHY10 / QHY168C / QHY247C. In my opinion the QHY600 is the best camera. I’m using it with TS APO 130mm, for this setup camera allow to:
    – maximum usage of telescope capabilities – telescope works near angular resolution border
    I don’t regret buying of this camera.
    – give huge field of view 3×2 degrees
    – join two worlds – on one image I have huge panorama with a wealth of details
