QHY 5III 485C Color camera

QHYCCD announces a new addition to its line of high speed, high QE, low noise, planetary cameras, the QHY5III485C.

This new camera uses Sony’s new IMX485, back-illuminated, 8.4 megapixel color CMOS sensor with an array of 3864 x 2180 pixels at 2.9um. With USB 3.0 interface, the full-frame rate of 44 FPS at 8-bits or 18.5 FPS at 16-bits. Smaller regions of interest will yield even faster frame rates.

This new camera makes a great planetary combo with the other newly released QHY5III462C.

The resolution of the QHY5III485C camera is 16:9, which is equivalent to the mainstream video output ratio. With the native high resolution, 485C can play a special role in recording astronomical video and astronomical science live broadcast.

Besides is specially equipped with 128MB DDR built-in image buffer. In non-video output mode, DDR built-in buffer can effectively relieve the transmission pressure brought by high-resolution large data volume and reduce information loss.

Multiple functions – With fisheye lens to realize an all-sky camera. The QHY5III485C standard package includes a 2.5mm Fisheye lens that converts the planetary camera into a high-resolution, 8.4 Megapixel All Sky camera with 180-degree field of view.

Large Sensor Size

The QHY5III485C has 4 times the area of the smaller QHY5III462C. and 4 times the number of pixels. In the area, it is the same size as the popular IMX174 sensor but with back illumination and higher resolution. The generous field of view provided by this larger sensor makes it ideal for solar and lunar imaging whereas the smaller, faster QHY5III462C. with its enhanced IR response is superior for imaging planets like Jupiter, Saturn, and Mars.

High QE and sHCG While the QHY5III485C does not have the extended near IR response of the QHY5III462C, it does have sHGC (Super High Cain Conversion) for exceptionally low (less than 1e-) read noise. For solar and lunar imaging, the NIR response is not required but the ability to take multiple short exposures in H-alpha light is ideal for solar use and making movies of solar prominences, arcs and eruptions.
