New! QHY-5-III-485C Color Planetary and AllSky Camera
We are pleased to announce a new addition to QHYCCDs line of high speed, high QE, low noise, planetary cameras, the QHY-5-III-485C. The QHY-5-III-485C uses Sony's new IMX485, back-illuminated, 8.4 megapixel color CMOS sensor with an array of 3864 x 2176 pixels at 2.9um. With USB 3.0 interface, the full frame rate of 18.5 FPS at 16-bits or 44 FPS at 8-bits. Smaller regions of interest will yield even faster frame rates. This new camera makes a great planetary combo with the other newly released QHY 5-III-462C CMOS Camera (various versions available) .
Large Sensor Size
The QHY-5-III-485C has 4 times the area of the smaller QHY-5-III-462C and 4 times the number of pixels. In 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 QHY 5-III-462C CMOS Camera (various versions available) with its enhanced IR response is superior for imaging planets like Jupiter, Saturn and Mars.
The following 3 images show (from left to right) the field of view of QHY-5-III-485C: Sun at a focal length of 560mm, Sun at a focal length of 2000mm and QHY 462 C: Jupiter at a focal length of 8000mm.
High QE and sHCG (Super High Cain Conversion)
While the QHY-5-III-485C 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.
Combination All Sky Camera
The QHY-5-III-485C standard package includes a 2.5mm Fisheye lens that converts the planetary camera intoa high-resolution, 8.3 Megapixel All Sky camera with 180-degree field of view. The following items are included with the camera:
- Camera body
- USB3.0 Cable
- Tracking Cable
- Focus Position Locking Ring
- 2.5mm All Sky Lens
- C-mount extension ring
- 1.25" extension tube
Further technical details are shown in the following 4 graphic curves of the QHY 485 C:
