Ask a Question About This Product

The QHY5III174C is the first in the new QHY5III series CMOS USB 3.0 cameras.

The camera is designed to be an excellent planetary, lunar, solar and meteor capture video camera. With a 50mm, F/1.4 C-mount lens it will record 8th to 9th magnitude stars at 30 frames per second (33 ms exposure).  This high sensitivity with HD resolution will push video astronomy to new heights. 

Sony introduced a new global shutter (GS) CMOS imaging technology called PregiusTM that redefines the global shutter imaging category and provides the best of both worlds:  fast frame rates and CCD-like imaging performance.  The technology also offers reduced dark noise, which enables higher gains without compromising image quality, as well as higher quantum efficiency.    The global shutter eliminates pixelization when imaging the moon and planets and moon caused by atmospheric agitation and high frame rates. 

The unique QHYCCD design retains the 1.25-inch eyepiece design of the QHY5-II series but adds features for better cooling.  This design is more efficient in transfer of heat to the outer case enabling lower noise especially in high ambient temperatures.  

The 1.25 inch design also offers the shortest possible back focus, making the camera ideal for off-axis guiding.  In addition, the QHY5III174C uses a more robust LEMO style connector for the guide port.  These connectors are known for being both rugged and reliable.  

The QHY5III174 is available in both mono and color versions.

The camera is well suited for solar imaging using short focal length telescopes that will capture a full solar disk within the FOV.
