QHYCCD QHY600PH: High-Performance CMOS Astrophotography Camera
Key Features:
Advanced Sony IMX455 Sensor: The QHY600 Series utilizes the Sony IMX455 BSI full-frame sensor with 3.76um pixels and native 16-bit A/D conversion, available in both monochrome and color versions.
Ultra-Low Dark Current: Boasts extremely low dark current (0.002e/p/s @ -20C) thanks to Sony’s Exmor BSI CMOS technology.
Zero Amplifier Glow: The QHY600PH camera ensures clear imaging without amplifier glow interference.
High Sensitivity and Speed: Delivers only one electron of read noise at high gain with a full resolution readout speed of 4FPS, ideal for photon-limited conditions such as short exposures and narrow-band imaging.
Large Image Buffer: Equipped with a 2GB DDR3 image buffer for smooth data transfer of the entire 60MP sensor, especially important for computers with limited processing power or USB 3.0 support.
Improved Full Well Capacity: The back-illuminated CMOS structure allows more light absorption, resulting in higher quantum efficiency and sensitivity.
True RAW Data Output: Offers authentic RAW image output without noise reduction or hot pixel removal, preserving the integrity of astronomical images.
Efficient Cooling & Anti-Dew Technology: Features dual-stage TE cooling and an electric heating board to control dark current noise and prevent dew formation.
Robust Sealing Technology: Utilizes silicon gel tube socket design for humidity control within the sensor chamber, ensuring no oil leakage.
Diverse Naming Options: The QHY600PH is available in various models tailored for different applications – from Photographic (PH) to Scientific (Pro) grades.
USB3.2 Gen1 Type-C Interface: Features a more durable and flexible Type-C interface, enhancing connectivity and longevity.
Universal ST-4 Guiding Interface: The QHY5III (Ver.2) cameras come with a universal ST-4 compatible guiding interface for easy replacement.
Status Indicator LED: The camera includes a status indicator at the back, assisting in diagnosing camera statuses with different colored lights.
Easy Remote Reboot: Designed for remote observatory control, the camera can be rebooted using the +12V power supply without needing to disconnect the USB interface.

Unity Gain*
25 (Extended Full Well Mode) *
*With the improvement of the CMOS technology, the 16bit CMOS camera has been released, like QHY600/268/411/461. For these cameras, even in lowest gain it has beyond the requirement of unit gain (less than 1e/ADU due to sufficient samples) So you can directly set gain 0 as start. Please note QHY600/268C/411/461 has extend full well mode. In this mode you still need to find out the unit gain position.
