QHY5III485C

The QHY5III485C is a planetary and guiding camera designed for astrophotography. Let’s explore its features:

• Sensor and Resolution:

  • The QHY5III485C uses the Sony IMX485 sensor, which is a back-illuminated, 8.4-megapixel color CMOS sensor.
  • The sensor has an array of 3864 x 2180 pixels with a pixel size of 2.9μm.
  • With a USB 3.0 interface, the camera achieves a full frame rate of 44 FPS at 8-bits or 18.5 FPS at 16-bits.
  • Smaller regions of interest (ROIs) will yield even faster frame rates.
  • The resolution of the QHY5III485C is 16:9, equivalent to the mainstream video output ratio.
  • It can play a special role in recording astronomical videos and live broadcasts for astronomical science¹.

• All Sky Application:

  • The QHY5III485C standard package includes a 2.5mm Fisheye lens that converts the planetary camera into a high-resolution, 8.4-megapixel All Sky camera with a 180-degree field of view.
  • This feature allows you to capture wide-angle views of the entire sky, making it suitable for monitoring meteor showers, auroras, and other celestial events.
