Introducing the QHYCCD QHY5III585C
The QHYCCD QHY5III585C is a new-generation color camera designed for planetary, lunar, solar (with suitable filter) and guidance imaging. Equipped with the Sony IMX585 backlit CMOS sensor, it offers a high resolution of 8.4 megapixels, enhanced sensitivity in the near infrared (NIR) and improved dynamic range thanks to Sony Starvis II technology. Compact and powerful, this camera is ideal for capturing precise details of celestial objects.
Main technical specifications
- Sony IMX585 CMOS sensor :
- Size: 1/1.2 inch (11.1 mm x 6.3 mm).
- Resolution: 8.4 megapixels (3856 x 2180 effective pixels).
- Pixel size: 2.9 µm, ideal for medium- and long-focus configurations.
- Backlit structure (BSI) with enhanced red and near-infrared sensitivity.
- Native sampling depth :
- 12-bit ADC with output in 16-bit or 8-bit formats.
- Full Well Capacity :
- Up to 32 ke-, around three times greater than that of its predecessor, the QHY5III485C.
- Low playback noise :
- Between 0.8 e- and 5.5 e-, offering excellent image quality even in low light.
- Exposure time :
- Adjustable exposure range from 11 µs to 900 seconds, allowing great flexibility for different types of celestial objects.
Optical Performance
- Acquisition frequencies (Full Frame) :
- Full resolution (3856 x 2180) :
- 41.5 FPS @8 bits,
- 23.5 FPS @16 bits.
- ROI (Region of Interest) :
- Resolution adjusted for higher speeds :
- 1920 lines: 82 FPS @8 bits, 47 FPS @16 bits.
- 640 lines: 135 FPS @8 bits, 79 FPS @16 bits.
- Enhanced near infrared (NIR) sensitivity :
- Thanks to a deeper photodiode in each pixel, the sensor is almost as sensitive to NIR light as to visible light. This enables detailed observations in these wavelengths, particularly for gas giants such as Jupiter and Saturn.
Design and Connectivity
- Integrated DDR3 buffer memory (512 MB) : Reduces pressure on data transmission to the computer during fast imaging sessions.
- High-speed USB3.2 Gen1 Type-C interface : Ensures fast, reliable transfer for high-resolution acquisitions.
- Integrated ST-4 port : Compatible with standard guide mounts for precise tracking.
- Extended optical compatibility :
- Connection to telescope via standard 1.25" adapter, compatible with CS and C lenses after replacement of front adapter.
- Filters included :
- IR850nm filter to capture near-infrared detail.
- Integrated IR-Cut filter to block infrared rays when observing in the visible spectrum.
