Lowest Readout Noise, Fast frame rates (120+ FPS)
QHY5III462C uses the latest (6th Generation) 2.1 megapixel IMX462 STARVIS CMOS sensor from Sony (available in color only). The pixel size is 2.9µm making it the same size and resolution as the sensor used in the QHY5III290 camera (product is dicontinued) that has been so successfully used for planetary imaging by some of the best planetary imagers in the world. The QHY462C has a fast USB 3.0 interface.
The IMX462 sensor is back-illuminated and has new features that give it two significant advantages over other planetary cameras:
Baader Methane-Filter 1¼" (889nm, 8nm) (#2458295 , € 239,- )
- the IMX462 sensor has sHGC for extremely low read noise (less than one electron) at high gain. This is ideal for stacking hundreds or thousands of short planetary images.
- it is exceptionally sensitive in the NIR. In this generation of sensor, the photodiode portion of the pixel well is deepened, allowing photons of longer wavelength to penetrate deeper into the substrate and thereby dramatically increases the sensor's sensitivity to red light and near infrared light (NIR). The RGB filters over the pixels become transparent at NIR wavelengths, so the sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum.
The peak QE in the NIR around 800nm is as high or higher as the peak QE in the visible wavelengths. For planetary imagers using a methane filter that passes light around 880nm this is welcome news.
Innovative cooling concept
By including four proprietary cooling segments with a larger diameter at the end of the camera, the cooling surface of the otherwise cylindrical camera housing is significantly increased. This results in faster and higher thermal dissipation from the inner area of the camera to the outside environment.
The QHY5III462C camera will include two 1.25" screw-in filters, a UV/IR cut filter to isolate the visible wavelengths for normal RGB imaging and an IR850 filter that will cut the visible wavelengths but pass wavelengths above 850nm. Together, this yields a camera that can image in (a) visible light only, or (b) NIR light only, or (c) combined visible and NIR. Passing all the light, visible and NIR, will produce a very sensitive luminance frame (when shot through a reflector or other scope capable of focusing visible and NiR together) for producing LRGB color images.
The QHY 5 III 462 C is available with two different accessory sets:
- QHY-5-III-462C High Speed USB3.0 Camera
- USB Cable
- Tracking Cable
- Focus Locking Ring
- C-mount adapter
- 1.25" UV/IR filter
- 1.25" IR850 filter
- 1.25" Methane filter (890nm) with 10nm half-width for photography of large gas planets
- Wide Angle all sky lens with f = 2,5mm - f/1.2
- CS mount adapter for connecting the lens to the camera
The Expansion Kit #1931028 is also available separately.
