QHY 174 - fast monochrome CMOS Camera with Cooling

The ALccd-QHY 174 belongs to a new series of cooled USB 3.0 cameras. With its sensor, it is an excellent camera for the solar, lunar, planetary and meteor photography, but with the cooling, it works also also a low-noise and highly sensitive camera for deep sky photography.

The integrated DDRII cache of ALccd-QHY cameras 174, 178 and 290 has a memory size of 128MB and ensures that no image will be lost when downloading. It is also the prerequisite for even in low-performance PCs and USB2.0 to have no loss of picture or to download an image at all.

Sensor and shutter

In the ALccd-QHY 174, 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

The sensor chamber of the cooled ALccd-QHY cameras 174, 178 and 290 is sealed and is heated with a special heating. Thus, fogging is counteracted, particularly in application areas with high humidity.

The cameras are very compact, which takes effect especially for smaller, portable telescopes, but a small camera is also beneficial when used in special technical assemblies.

The ALccd-QHY 5III 174 camera is also available as color version.

System requirements

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.

Included is the original recording software "EZCAP".

The operating software is Windows 7, 8 and 10 compatible and supported by 32- and 64-bit.

In addition, we recommend the ASCOM compatible software packages MSB AstroArt or MaxIm DL.


The ALccd-QHY cameras 174, 178 and 290 cameras require an external power supply with 12V and min. 3A.

The power consumption is up to 27W (100% cooling) with minimum at 8W (cooling off).
