QHYCCD Cooled QHY128C CMOS Color Camera

The QHY128C cooled CMOS camera is one of the best performing cameras in QHYCCD's COLDMOS line. With a sensor made specifically for astronomical use, this camera is equipped with a custom thermal noise reduction technology. The camera also outputs a True RAW data that results in the dark current of this camera to be a remarkable 0.0006e-/p/s at -15C. This is the lowest dark current of any camera in the COLDMOS line!

The QHY128C optical window has high quality AR+AR multi-layer coatings and the sensor surface is AR coated as well. These coatings significantly reduce halos around bright stars when capturing the images.

With anti-amp glow technology, the QHY128C is equipped with zero amplifier glow. This is apparent even in long exposures! This feature definitely sets the camera apart.

High Quality Performance

This QHY cooled color camera uses the Sony IMX128, full frame, 35mm format, 24 Mehapixel, 14-bit CMOS sensor. It also has a high dynamic range of more than 14 stops!

True RAW Image Output

The QHY128C offers a feature called True RAW Image Output. This produces an image made of the original signal only, and, therefore, maintaining the maximum felxibility for post-aquisition image processing systems.

Unique Thermal Noise Reduction Technology

Along with the 2-stage thermoelectric cooling, this QHYCCD camera uses a thermal noise technology to reduce CMOS sensor noise without affecting the quality of the raw image.

Zero Amplifier Glow

This QHY color camera has a zero amplifier glow that is independent from exposure length.

128MB DDRII Image Buffer

The QHY128C has a 128MB DDRII image buffer to cache the image. This avoids the risk of a frame loss. The image data is stored in the DDR after the image is aquired, and then it is transferred to the computer from the memory buffer. Doing this avoids problems of a busy USB port.

Anti-Dew Technology

The QHY128C features full anti-dew technology for both the CCD sensor cover glass and the sensor chamber optical window. The QHY128C has an electric heating board made for the chamber window to prevent dew formation. The sensor is kept dry using a silicon gel tube socket design to control humidity in the sensor chamber.

AR+AR Optical Window

The QHY128C has a AR+AR coated optical window to avoid halos around bright stars. This gives full access to the red wavelength of H-alpha and SII. For RGB color balance, a separate removable 2-inch UV/IR filter is placed in a custom filter holder in front of the camera. This is done without passing the near IR wavelengths above 700nm.
