The QHY5III485C uses Sony's new IMX485, back illuminated, 8.4 megapixel colour CMOS sensor with an array of 3864 x 2180 pixels at 2.9um. With USB 3.0 interface, a maximum full frame rate of 44 FPS at 8-bits or 18.5 FPS at 16-bits and up to 190FPS with Region of Interest set to 480 lines, typical when imaging planets.
The format of the QHY5III485C is 16:9, which is equivalent to the mainstream video output ratio. With native ‘4K’ high resolution, the QHY5III485C can play a special role in recording video for astronomical science live broadcasts.
The large 1/1.2” sensor provides the same area as the popular IMX174. This makes it not only much easier to find objects at high magnifications, but also makes it a good choice for lunar and some types of solar imaging.
QHY5III485C is equipped with 128MB DDR built-in image buffer. In non-video output mode, the DDR buffer relieves the transmission pressure brought by high-resolution large data volume and reduce information loss.
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.
