QHY5III485C - colour planetary and all-sky camera

CHYCCD is pleased to announce a new addition to its line of high speed, high QE, low noise, planetary cameras, the QHY5III485C. 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. This new camera makes a great planetary combo with the other newly released QHY5III462C.

Large Sensor Size – The QHY5III485C has 4 times the area of the smaller QHY5III462C and 4 times the number of pixels. In area it is the same size as the popular IMX174 sensor but with backillumination 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.

While the QHY5III485C does not have the extended near IR response of the QHY5III462C, it does have sHGC (Super High Gain 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.

Combination 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. The following items are included with the camera: 1. Camera body 2. USB3.0 Cable 3. Tracking Cable 4. Focus Position Locking Ring 5. 2.5mm All Sky Lens 6. C-mount extension ring 7. 1.25″ extension tub.
