Side by side compares at the same exposure time and same temperature. From this image, we know the amp-control can reduce both the amp light and the thermal noise.
QHY 5III174 is the first in the new QHY5III 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 gets 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 back focus, making the camera ideal for Off-Axis guiding. In addition, the QHY5III174 uses the LEMO style connector for the guide port. These connectors are known for being both rugged and reliable connectors.
QHY5III174 has 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.
