Introducing the QHY5III462M (monochrome) and QHY5III462C (color) cameras
The QHYCCD QHY5III462M (monochrome) and QHY5III462C (color) are specialized cameras for planetary, lunar, solar (with suitable filter) and guidance imaging. Equipped with Sony's 6th-generation IMX462 STARVIS backlit CMOS sensor, they offer 2.1-megapixel resolution and exceptional sensitivity in the visible and near-infrared (NIR) ranges. Thanks to their low read noise and high acquisition speed, these cameras are ideal for capturing precise details of celestial objects.
Main technical specifications
- Sony IMX462 CMOS sensor :
- Size: Typical 1/2.8" (6.46 mm x 3.64 mm).
- Resolution: 2.1 megapixels (1920 x 1080 effective pixels).
- Pixel size: 2.9 µm, ideal for medium- and long-focus configurations.
- Backlit structure (BSI) with enhanced near-infrared sensitivity.
- Native sampling depth :
- 12-bit ADC with output in 16-bit or 8-bit formats.
- Full Well Capacity :
- Up to 12 ke-, for capturing high-contrast scenes without saturation.
- Low playback noise :
- As low as 0.5 e-, ideal for short exposures or low-light images.
- sHCG (Super High Conversion Gain) technology :
- Enables efficient conversion of small loads to high voltage, increasing sensitivity in low-light conditions.
- Exposure time :
- Adjustable exposure range from 7 µs to 900 seconds, offering great flexibility for different types of celestial objects.
Optical Performance
- Acquisition frequencies (Full Frame) :
- Full resolution (1920 x 1080) :
- 135 FPS @8 bits,
- 60 FPS @16 bits.
- ROI (Region of Interest) :
- Resolution adjusted for higher speeds in selected areas.
- Enhanced near infrared (NIR) sensitivity :
- The IMX462 sensor is almost as sensitive to NIR light as to visible light, with a quantum efficiency peak around 800 nm, enabling detailed observations of gas giants such as Jupiter and Saturn.
Design and Connectivity
- High-speed USB3.0 interface : Ensures fast, reliable transfer for high-resolution acquisitions.
- Integrated ST-4 port : Compatible with standard guide mounts for precise tracking.
- Interchangeable optical window :
- The QHY5III462C comes with two 1.25" screw-on filters:
- A UV/IR-cut filter to block infrared radiation when observing in the visible spectrum.
- An IR850 filter for capturing near-infrared details.
