QHYCCD QHY294C Pro color camera


QHYCCD QHY294C Pro camera uses a Sony IMX294 back-illuminated color sensor with 23.2mm diagonal and high sensitivity, 4164 x 2796 resolution, 14-bit A/D, very low 1e- read noise at highest gain and a powerful cooling system (down to -35°C in respect to ambient temperature). All of this at a very affordable price that makes the QHY294C Pro a great camera for astrophotography.

Back-illuminated sensor with 4.6um pixels and 64ke- Full Well

Benefiting from the back-illuminated structure, the area around the photo-diode is reduced so that for a given pixel size the BSI sensor provides a greater full well capacity compared to a front illuminated sensor. The QHY294C Pro has a full well capacity of nearly 65,000 electrons with 4.63um x 4.63um pixels, almost the same as an interline CCD camera with 9um pixels.

Expanded Pixel Mode: 11.7MP to 46.8MP

The IMX294 chip has 46.8 million 2.315um pixels, which Sony 2x2 bins on-chip to create the sensor's advertised 11.7 million 4.63um pixel array. The QHY294 Pro series camera is capable of locking and unlocking the on-chip binning to provide two readout modes. The first mode reads the sensor "locked" mode to produce 11.6mp images with 4.63um pixel size and 14 bits per pixel. The second read mode unlocks the binning to produce 46.8mp images with 2.315um pixel size at 12 bits per pixel.



High QE and Low Readout Noise

Preliminary tests indicate that this sensor has an outstanding performer with extraordinarily high QE, low read noise, and low dark current. The QHY294C Pro has 6.8 to 6.9e- read noise at the lowest gain, 1.6e- read noise near unity gain, and 1.0e- read noise at highest gain, with great dynamic range!

Anti-Dew Technology and flexible adapters

The QHY294C Pro benefits from more than a decade of cooled camera design experience. QHYCCD has implemented full dew control solutions. The optical window has a built-in dew heater and the CMOS chamber is protected from internal humidity condensation. QHY294C has a short back focal distance allowing for flexibility in setting up your optical train.
