The ALccd-QHY III 178 is, from the III rock USB3.0 series, the model with the smallest pixels. It is ideal for short focal length optical systems and highest resolution. It is an excellent camera for the solar, lunar, planetary and meteor photography, but also a low-noise and highly sensitive camera for deep sky photography.
With a standard C-mount lens 50mm f/1.4, you can reach stars of 8th to 9th magnitude live in a video stream at 50 frames per second (about 20 ms exposure time). This offers a new dimension in high-sensitivity HD video photography!
Sensor and shutter
In the ALccd-QHY 5III 178, the built-in sensor works in "rolling shutter" mode. The STARVIS back-illuminated sensor technology allows the highest sensitivity and quantum efficiency in the visible and infrared range of light. If you are looking for a very sensitive sensor for low-light applications (2000 mV or more at 1 micron^2 when a 706 cd / m2 light source F5.6 in 1 s exposure), then you are absolutely aright with this model.
The housing shape is designed so that the camera, like the proven ALccd-QHY 5-II models, fits into standard 1.25" focusers or adapters. The fins provide for a fast and selective dissipation of the heat which is produced during the exposure.
The back focus is minimal, so that the camera can also be used in most off-axis guiders for auto guiding. The Lemo connector on RJ12 is robust and compatible to most mount controllers on the market.
The ALccd-QHY 5III 178 camera is also available as color version.
The camera has an advanced electronics that makes a PC with USB 2.0 support necessary. The maximum performance can be reached only with a powerful USB 3.0 computer.
The operating software is Windows 7, 8 and 10 compatible and supported by 32- and 64-bit.
