1. Fast Data Transfer
The QHY5III-series are fast and sensitive astronomy cameras and autoguiders. They use a 5Gbps USB3.0 interface and have a maximum 350MByte/s transfer speed of image frames, ideal for high speed imaging of fast-rotating planets.
2. Advanced Heat Design
QHY5III-series cameras incorporate an advanced thermal design that helps transfer heat generated by the sensor and electronics to the metal case of the camera quickly. Heat is dissipated by the cooling fins and by the eyepiece holder of your telescope.
3. Compact Robust Design
Like the QHY5II-series, the QHY5III-series cameras feature a compact body that slides into a 1.25” eyepiece holder. Each camera also includes an adjustable location ring to make it confocal with an eyepiece. The QHY5III-series also includes an extremely robust and stable 5-pin aircraft-spec socket for a secure, solid connection between the camera and other devices. The cameras come with a 5-pin-LEMO-to-RJ11 guide cable for autoguiding.
4. Fast, Sensitive Camera for Planetary Imaging and EAA
The QHY5III-290C color camera uses the IMX290 STARVIS Exmor R back-illuminated CMOS sensor. This 1/2.8-inch sensor has ultralow readout noise and full 1920x1080 HD resolution with small 2.9um pixels, ideal for planetary imaging. The QHY5III-290C uses a fast USB 3.0 interface with 135 fps data transfer at full HD output. Low-noise performance and the back-illuminated sensor, which collects more light at the pixel level, makes this a perfect camera for capturing real-time images for electronically-assisted astronomy (EAA).
Software support includes: EZPlanetary, SharpCAP, FireCapture, Native WDM, BroadCast WDM and ASCOM.
