The ALccd-QHY 5III 174 is the first model of a series of new USB 3.0 cameras. 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 30 frames per second (about 30 ms exposure time). This offers a new dimension in high-sensitivity HD video photography!
Sensor and shutter
In the ALccd-QHY 5III 174 color, the built sensor uses technology in the "global shutter" mode (Pregius TM) combines high frame rates with high quality, CCD-like image results. Other highlights include lower noise level, higher quantum efficiencies and ways to set higher gain values to.
The global shutter prevents smearing / pixelizing of moving objects, for example, also artifacts caused by atmospheric movements at higher frame rates at the moon/sun/planetary photography.
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 174 camera is also available as monochrome 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.
