  • Microsecond precision in the global shutter for the most precise timings possible.
  • See specifications below.

Product Details

  • The QHY174 camera is designed to be an excellent planetary, lunar, solar and meteor capture video camera. With a 50mm F1.4 lens it will record mag 8 to mag 9 stars in live video recording at 30FPS (33ms exposure), several magnitudes fainter than can typically be seen with the naked eye. The QHY174’s high sensitivity with HD resolution will push video astronomy to new heights.

    The QHY174GPS camera uses the 1/1.2-inch SONY IMX174 CMOS sensor with global shutter, 5.86um pixels,138FPS@1920*1200, high QE of 78%, and low read noise of 3-5e-. It is useful for imaging occultations, eclipses, meteors, and other scientific imaging requiring a highly precise recording of the time and location of the observation on every frame.

    The QHY174GPS has a unique built-in GPS module that can sync with the atomic clock signals received from GPS satellites. The QHY174GPS can record the start and end of exposure time with 1us precision anywhere on earth. The QHY174GPS was selected by the NASA New Horizons Team to successfully captured the MU69 occultation in the Summer of 2017. The QHY174M-GPS has dual stage TE cooling to -45C below ambient with full anti-moisture control including heated optical window and removable desiccant plug for the sensor chamber. The QHY174 also has an anti-amp glow function. It can reduce the IMX174 sensor’s amplifier glow significantly in long exposures.

    Global Shutter

    Unlike a rolling shutter, a global shutter guarantees that the exposure time for the whole image area is uniform, beginning and ending at exactly the same time. This type of shutter is ideal for high precision time-domain applications.

    The QHY174M-GPS will record the global shutter exposure starting and ending time with microsecond precision. Two QHY174 cameras, for example, each located anywhere in the world, can have the same time base, accurate to microseconds. In order to guarantee the starting and ending time of the exposure, the QHY174 has a built-in LED pulse calibration circuit precise to 1 microsecond.

    Double Working Modes

    Master mode: In Master Mode, the camera is free running and the internal 10MHz GPS synced clock will measure and record the shutter’s opening and closing time.

    Slave mode: In Slave Mode you can input a target start time and the interval period for two frames. For example: You want three cameras in different locations (maybe thousands of kilometers apart) to start an exposure at 2016.3.9.UTC 14:00:00.000000 and then to continue with exposures at the interval time of 0.100000 sec. After you input these value, all the three cameras will wait until this time and then simultaneously start video recording.
