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.
  • Specifications:

    • Model: QHY5III485C
    • Image Sensor: Sony IMX485 (Color Only)
    • Sensor Size: 1/1.2 inch
    • Pixel Size: 2.9μm x 2.9μm
    • Effective Pixel Area: 3864 x 2180
    • Effective Pixels: 8.4 Megapixels
    • Full Well Capacity: 12ke-
    • Read Noise: 0.77e- to 2.4e-
    • A/D: 12-bit (output as 16-bit and 8-bit)
    • Built-in Image Buffer: 128MB DDR II Memory
    • Full Frame Rates: 44 FPS @ 8-bits
    • ROI Frame Rates: Vary based on selected lines (e.g., 78.5 FPS @ 1200 lines, 87 FPS @ 1080 lines, etc.)
    • Exposure Time Range: Adjustable
    • Shutter Type: Electronic Rolling Shutter
    • Computer Interface: USB 3.0 Type-B
    • Guide Port: Custom ST-4
    • Telescope Interface: 1.25-inch, with CS and C-Mount
    • Optical Window: IR-Cut Filter (Extra filter available)
    • Back Focal Length: 12mm
    • Weight: 90g

In summary, the QHY5III485C combines high resolution, low noise, and efficient memory handling, making it suitable for both planetary imaging and all-sky monitoring applications1. You can find more information about this camera on the QHYCCD website.
