QHY5III715C

Introducing the QHYCCD QHY5III715C

The QHYCCD QHY5III715C is an ultra-high-resolution color camera, specially designed for planetary, lunar and solar imaging (with suitable filter), as well as for precise guidance. Equipped with the Sony IMX715 backlit CMOS sensor, it offers 4K resolution with exceptionally small pixels of 1.45 µm, making it ideal for short focal length refractors and configurations requiring high precision. Thanks to its enhanced sensitivity in the visible and near-infrared range, this camera is a perfect choice for capturing incredible detail.

Main technical specifications

• Sony IMX715 CMOS sensor :
• Size: 1/2.8 optical format (5.6 mm x 3.2 mm).
• Resolution: 8.4 megapixels (3840 x 2192 effective pixels).
• Pixel size: 1.45 µm, ideal for fields of view of less than 1 arcsecond with focal lengths of 300 mm or more.
• Backlit structure (BSI) with enhanced red and near-infrared (NIR) sensitivity.
• Native sampling depth :
• 12-bit ADC with output in 16-bit or 8-bit formats.
• Full Well Capacity :
• Up to 5.7 ke-, reducing the risk of saturation in bright areas.
• Low playback noise :
• Between 0.87 e- and 2.17 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 (3840 x 2192) :
• 42 FPS @8 bits,
• 23 FPS @16 bits.
• ROI (Region of Interest) :
• Resolution adjusted for higher speeds :
• 1920 lines: 83 FPS @8 bits, 47 FPS @16 bits.
• 640 lines: 99 FPS @8 bits, 99 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, enabling detailed observations in these wavelengths.

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.
