The QHY5-III 174 C is the first in the new QHY5-III series CMOS USB3.0 cameras. The camera is designed to be an excellent Planetary, Lunar and Solar and meteor capture video camera. With a 50mmF1.4 C-mount lens it get star up to mag 8 to mag 9 at 30FPS(33ms exposure) live video recording. This high sensitivity with HD resolution will push the video astronomy to a new height.
Sony introduced a new global shutter (GS) CMOS imaging technology called PregiusTM that redefines the GS CMOS imaging category and provides the best of both worlds with fast frame rate and CCD-like imaging performance. The technology offers lower dark noise, which enables higher gains without compromising image quality, as well as higher quantum efficiency.
The global shutter eliminates pixelization when imaging the Planets and Moon caused by atmospheric agitation and high frame rates.
The unique QHYCCD design keeps the 1.25inch eyepiece design. The advantage of this design is a more efficient 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 QHY5-III 174 uses the LEMO style connector for the guide port. These connectors are known for being both rugged and reliable connectors.
QHY5-III 174 has both mono and color version. The camera is well suited for solar imaging using short focal length telescopes that will capture a full solar disk within the FOV.

The QHY5-III 290 Mono uses a SONY STARVIS Exmor R back illuminated CMOS sensor. The Starvis sensor allows you to “see” very dim stars in real time video. The QHY5-III 290 can capture mag 9 stars when connected to a 50mm F1.4 C-mount lens. Compared with the IMX236 sensor it has twice the sensitivity to visible light and more than three times in the near infrared.
The QHY5-III 290C uses a SONY STARVIS Exmor R back illuminated CMOS sensor. The Starvis sensor means you can see very dim stars in real time video. The 2.9um pixel size is also idea for planetary imaging.
