QHYCCD 268C-PH Camera: Advanced Imaging with CMOS Technology

Key Features:

  • Cutting-Edge CMOS Sensor: The QHY268M/C features a new generation back-illuminated CMOS sensor, offering low readout noise and high-speed readout for superior astronomical imaging.

  • High-Resolution and Sensitivity: Equipped with a Sony IMX571 sensor, this camera delivers true 16-bit A/D conversion and 3.76um pixels, ensuring detailed and high-quality images.

  • Amplifier Glow Free: The QHY268M/C stands out as an amplifier glow-free camera, a significant advantage for capturing clear night sky images.

  • Large Image Buffer: Comes with a 1GB DDR3 image buffer to handle the high data throughput of the 26MP sensor, ensuring smooth and uninterrupted image capture.

  • Humidity Sensor in QHY268M: The QHY268M model includes an internal humidity sensor for monitoring conditions, a feature not available in the QHY268C variant.

  • Backside Illumination (BSI) Technology: Improved full well capacity due to the BSI structure, enhancing the sensor's efficiency in converting photons to electrons.

  • True RAW Data Output: QHY Cameras provide authentic RAW image output, maximizing flexibility for post-acquisition processing without the common drawbacks found in DSLR implementations.

  • Effective Cooling and Anti-Dew Control: Dual-stage TE cooling and proprietary technology control dark current noise, with a built-in dew heater and sealed chamber to prevent internal humidity condensation.

  • Professional Sealing Technology: Drawing on nearly 20 years of cooled camera design experience, the camera features a silicon gel tube socket for humidity control, ensuring no oil leakage.

  • Multiple Readout Modes: Specialized readout modes for QHY 16-bit Cameras, offering varied performance to suit different imaging requirements.

  • Thermal Noise Suppression: Innovative technology significantly reduces fixed-position thermal noise, characteristic of back-illuminated CMOS cameras.

  • UVLO Protection and USB Traffic Optimization: Protects against low voltage damage and minimizes horizontal banding in images through USB traffic adjustment.

  • Remote Reboot Feature: The camera can be rebooted remotely by controlling the +12V power supply, ideal for observatory setups.

  • Multiple Readout Modes with Enhanced Performance: Includes Photographic, High Gain, Extended Full Well, and 2CMS modes, each offering distinct advantages for astrophotography.

  • ASCOM, SharpCap, and N.I.N.A Support: The readout modes are supported in various software, allowing for versatile imaging options and settings.
