High Performance

Lowest Read Noise 14-bit A/D

The QHY247C uses a SONY IMX193 APS size color CMOS sensor. Pixel size is 3.91um and it has a 14-bit A/D with a full well capacity of 36ke-. The read noise is 1e- to 2.7e-, the lowest noise tested at the lowest gain in the entire QHYCCD COLDMOS product line making it ideal for stacking many short exposures.

True RAW Original Data

Many cameras claim to output RAW image files, but there is often still some internal processing performed on the image. This can have a negative effect on the image for astronomy such as the “star eater” effect. The QHY247C outputs TRUE RAW data, preserving the original data for maximum compatibility with astronomical imaging processing programs and other scientific imaging applications.

Low Dark Current

In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise in the QHY247C. As a result the dark current of this camera is a remarkable 0.0012e-/p/s at -15C.

Ultra-Low Reflection Halo Reduction

Halos around bright stars are caused by reflections between surfaces of elements in the optical path. An uncoated surface usually reflects about 8%-10% of the light striking it while a high quality multiple layer coating reflects only 1% or less. The IMX193 has superb quality AR coatings on the sensor and this can significantly reduce the halo effect.

24 Megapixels High Resolution

The QHY247C has 24 Megapixels, high resolution, 3.91um pixels in a 6024 x 4024 array. When combined with high quality telescope optics or even with the RASA telescope, the QHY247C can generate the large images that are ideal for large scale printing.
