  • Description

    ZWO ASI174MM Cooled Monochrome CMOS Imaging Camera

    ZWO's ASI174MM Monochrome CMOS Imaging Camera follows up on the popularity of the ASI120MM-S. However, the ASI174MM surpasses its predecessor in terms of cutting-edge functionality such as a high-speed USB hub, a standard 2” interface with M42 x 0.75 internal threads, and an AR window. However, the ZWO ASI174 camera has one important difference except, of course, for the two-stage TEC cooling function, and that is the inclusion of a Sony IMX174 monochrome CMOS sensor. This image sensor has a lot going for it when it comes to high quality solar, lunar, planetary, and deep sky imaging.

    Regulated Two Stage TEC Cooling!

    The cooled version of the ZWO ASI174MM camera allows the sensor to be cooled to 35C to 40C degrees below ambient. Below are the extra features that can be found on the camera body, specifically related to the cooling feature:

    • Just below the USB hub (dual 2.0 Out and 3.0 In), you'll find a 2.1 mm center positive input for a cooler power supply (not included). ZWO recommends 12VDC at 2A max.
    • Below the power supply input is a Cooler Power indicator LED light.
    • A huge heat sink, which is nearly 2/3 the size of the camera, is located on the side of the body.
    • The top of the camera sports a MagLev fan, which utilizes the attraction of the magnetic levitation force for low acoustic noise, high-temperature endurance, and long life.

    Sony IMX174 CMOS Sensor Features

    • 1/1.2” CMOS: The Sony IMX174 is a 13.4mm (Type 1/1.2) CMOS image sensor with 2.35 MP effective pixels in a 1936 x 1216 array. Pixel size is 5.86 µm.
    • Pregius Global Shutter: The development of a new pixel with analog memory allows for all pixels to be scanned at once. This global shutter function on the Sony IMX174 sensor means images taken of moving objects will not suffer from focal plane distortion, resulting in high picture quality. This is a really nice feature, especially when you are doing lunar or solar imaging. Bad seeing, wind, or movement can distort the image if the readout speed is not fast enough (<30fps).
    • Exmor High-Performance: Exmor is a Sony trademark, and that label means the CMOS image sensor is considered a high-performance model, with high-speed processing, low noise, and low power dissipation by using column-parallel A/D conversion.
    • High QE, Low Noise: As a general rule, we should be aiming for high QE and low noise. The peak quantum efficiency (QE) for the ZWO AI174 camera is 78%. The QE curve is slightly higher in B & G than the ASI120, and slightly lower is R and IR. Oh, the read noise? It measures out at only 6e-!
    • High Frame Rate: At full resolution, the Sony IMX174 sensor operates at 128.2 frames per second at 12 bit ADC and 164.5 frames per second at 10 bit ADC.
    • ROI Mode: Achieve an even higher frame rate with ROI (Region of Interest) mode. This mode allows you to set a maximum of 16 areas for capture inside the effective pixels area.
    • Everything you will need to control your ZWO camera is available and easily downloadable in one centralized location on the ZWO website. Click here for ZWO Software Download

    Cooler Power Supply Required. We recommend a 12V at 2.5A or more DC adapter and a battery from 9-15V to power your cooler.

    Please Note: This camera works with Windows 8.1 as long as you have the recommended driver installed (available on the ZWO website at zwoptical.com).
