QHY 533C Color Astrophotography Camera: Advanced CMOS Imaging

Key Features:

Revolutionary CMOS Technology: The QHY533M/C harnesses the power of CMOS technology, offering low readout noise and high-speed readout, ideal for astrophotography.
Back-Illuminated Sensor: Features a new generation back-illuminated CMOS sensor with 3.76um pixels, similar to flagship models QHY600 and QHY268, ensuring low noise and high sensitivity.
Improved Full Well Capacity: The back-illuminated structure allows more light to hit the photosensitive layer directly, resulting in improved quantum efficiency and sensitivity, especially beneficial for sensors with small pixels.
True RAW Data Output: QHY Cameras provide unaltered RAW image output, without any noise reduction or hot pixel removal, maintaining the integrity of astronomical images.
Advanced Anti-Dew Technology: Drawing on nearly 20 years of experience, the camera features comprehensive dew control solutions, including a built-in dew heater and a silicon gel tube socket to prevent internal humidity.
Efficient Cooling System: Equipped with dual-stage TE cooling and proprietary technology to control dark current noise, enhancing image quality.
Flexible Interface Design: The QHY533M and QHY533C models are designed for versatility, with the QHY533M easily connecting to the QHYCFW3S-SR filter wheel and DSLR lenses (additional adapter required).
Tripod Adapter Included: Both QHY533M/C models come with an additional adapter for tripod interface, facilitating easy shooting with DSLR lenses.
Optimized QHYCFW3S Adjustment for QHY533M: The QHYCFW3S-SR filter wheel has been updated to seamlessly connect with the QHY533M without needing to remove any parts, offering a short back focal length and easy setup.
Compatibility with QHYCFW3S-SR: The QHY533M is recommended to pair with the QHYCFW3S-SR for optimal use, while the included adapter in the CFW3S-SR package maintains compatibility with other models like QHY183 or QHY163.
