QHYCCD is proud to announce the release of an exciting new APS-C format color camera.The QHY247C uses a 24 Megapixel sensor with 3.91um pixels and has TE cooling to -35C below ambient.The QHY247C incorporates the latest technology and offers:

  • USB 3.0, 10 FPS@1920 x 1080 HD, 3 FPS@ 6024 x 4024 Full Frames
  • 1e- read noise at high gain, 2.7e- at lowest gain
  • High Dynamic Range
  • Zero Amplifier Glow
  • Unique Thermal Noise Reduction Technology
  • 128MB DDRII Image Buffer
  • True RAW Image Output
  • Anti-Dew Technology
  • Advanced AR Coatings on Optical Window, Sensor Glass and Micro lenses!
  • Anti-reflection Black Case for F2 Imaging Systems
  • High Precision Axis Calibration (no need for tilt corrections)

The Sony IMX193 sensor is the same sensor used in Nikon’s D5300 and D5500 cameras.The IMX193 has the lowest read noise and lowest thermal (dark) noise of any sensor in the QHY medium size camera product line.Additionally, the already low thermal noise is reduced even more by QHYCCD’s proprietary thermal noise reduction technology that does not affect the accuracy of the raw image.Amplifier glow can also be an issue with some CMOS cameras, but this new QHY model boasts the rare capability of zero amplifier glow, no matter how long the exposure.The image output is a true raw image, without any internal processing for maximum flexibility with image processing software.Other features include a 128MB image buffer that helps tremendously with slower computers using USB 2.0, and when running multiple cameras using the same computer.The optical window has built-in dew control and the chamber is protected from internal humidity condensation.In addition to AR coating on the optical window, the sensor cover glass and micro lenses are also AR coated for maximum halo suppression.The optical window is AR+AR coated, reducing halos around bright stars.IR blocking is not used so that the cameras can be used with maximum sensitivity to H-alpha and near IR light when desired, or a simple IR blocking filter can be attached for typical RGB imaging with IR cut.Each camera is carefully calibrated to high precision assuring flatness of the sensor to +/- 20 microns from edge to edge, eliminating the need for external adjustments by the user.
