QHY5III485 Colour Camera


4K resolution
The QHY5III485C uses Sony's new IMX485, backilluminated, 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.


16:9 resolution - More convenient video output
The resolution of QHY5III485C 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.


DDR built-in image buffer
QHY5III485C is specially equipped with 128MB DDR bulit-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
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.
