STARVIS means you can see very dim stars in real time video. The QHY5III290 can capture magnitude 9 stars with a 50mm F\/1.4 C-mount lens.  Compared to the IMX236 sensor, for example, the IMX290 has twice sensitivity for visible light and three or more times the sensitivity in near infrared.  The QHY5III290 also has ultra low read noise.  The back-illumination and low read noise make this camera an ideal video astronomy camera.  The small 2.9um pixel size is also ideal for planetary imaging.  The QHY5III290 has a fast USB 3.0 interface and produces 135FPS at full HD output . The camera has 10\/12-bit ADC and it outputs an 8-bit or 12-bit image.

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. \u003c\/p\u003e\u003cp\u003eThe 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 backfocus, making the camera ideal for off-axis guiding.  In addition, the QHY5III174 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. \u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp

Its 2.3 Megapixel sensor with large 5.86μm pixels captures data at a blistering 138 FPS over USB 3.0, freezing moments of atmospheric stability. With a deep 32ke- full well capacity and read noise as low as 2.2e-, the QHY5III174M pulls fine detail from both bright planetary disks and faint solar prominences.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eGlobal Shutter Imaging: The 1\/1.2-inch Sony IMX174\u003c\/h3\u003e\n\u003cp\u003eThe core of the QHY5III174M is its Sony IMX174 sensor, which features an electronic global shutter. Unlike rolling shutters that can distort fast-moving targets or warp images under turbulent seeing, a global shutter exposes all 2.3 million pixels simultaneously.
