QHY-5-III-585 Colour - 2nd generation
The QHY-5-III-585C is one of the first solar, lunar, planetary and guider cameras of the new 2nd generation of the QHY-5-III series. It is a further development with technical improvements of the
QHY 5-III-485C Planetary and All Sky Camera
(#1931030 , € 395,- € € 276.50)
.It has a similar high sensitivity in the near infrared as the first generation QHY 5-III-462C CMOS Camera (#1931026 , € 295,- € € 191.75) , while the performance in the dynamic range has been significantly improved. It has a large sensor with very low noise performance without readout glow. The new QHY-5 III-585C comes with a UV/IR blocking and an IR 850nm filter.
As one of the first models in the new 2nd generation of planetary cameras and guiders, the QHY-5-III-585C includes all the improvements and upgrades found in this latest camera series, including:
- Larger 512MB DDR3 internal image memory.
- Improved front-end design
- Compatibility with CS and C-mount lenses
- USB 3.2 Type-C interface
- Universal ST-4 guiding interface
- LED status indicator for malfunctions
- 1¼" body size for direct telescope connection
Enhanced sensitivity in the near infrared spectral range (NIR).
In the latest generation of Sony Starvis II sensors, the photodiode area of the imaging elements is physically deeper than in previous sensors, allowing photons with longer wavelengths to penetrate deeper into the substrate. This significantly increases the sensor's sensitivity to red and near-infrared (NIR) light. The sensor's peak sensitivity for NIR light is almost as high as for light in the visible spectrum (400 to 700 nm).
Increased dynamic range
The IM X585 is a Sony Starvis II sensor that offers not only high sensitivity but also a high dynamic range (HDR) of 88 dB, which is about eight times the previous generation IMX485 image sensor in a single exposure. Its sensitivity in the near-infrared range is about 1.7 times higher than that of the old IMX 485 C sensor.
USB 3.2 Gen1 Type-C interface
The 2nd generation QHY Kamers of the 5 III series now have a USB 3.2 Gen 1-C interface. It is designed for a longer life span and can transfer data at up to 5 Gb per second.
We recommend using the official data cable from QHYCCD. The market is flooded with a large number of inferior Type-C cables where it may cause the camera to malfunction. If you want to use your own cable, please make sure it is a high quality cable.
