QHY QHY5III174 Monochrome CMOS Camera

The QHY5III174 CMOS USB 3.0 camera is made to be a superb instrument for planetary, lunar, solar and meteor capture video. Sony came out with their new Pregius™ global shutter (GS) CMOS imaging technology that transforms GS CMOS imaging and gives users fast frame rates along with imaging performance similar to that provided by a CCD sensor. This technology allows for higher quantum efficiency, as well as reduced dark noise for higher gains without losing any image quality. The global shutter gets rid of pixelization encountered during planetary or lunar imaging produced by atmospheric agitation and high frame rates.

The attachment of a separately sold 50 mm f/1.4 C-mount Lens enables the capture of stars as faint as magnitude 9 at 30 fps while recording live video. High sensitivity and HD resolution help take video astronomy to greater heights.

QHY's unique construction maintains the 1.25" eyepiece design. A major plus of this design is a more effective heat transfer to the exterior case for lower noise specifically in high ambient temperatures. The 1.25" design also optimizes this camera for Off-Axis guiding by providing the shortest possible back focus. Furthermore, the QHY5III174 uses the LEMO style connector for the guide port LEMO connectors are known for being tough as well as dependable.

The QHY5III174 CMOS Camera is also available in a color version. This camera is well-equipped for solar imaging with short focal length telescopes that absorb the full solar disk within the field of view.
