QHY 174 GPS Cooled Monochrome CMOS Telescope Camera
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-. 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 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 QHY174GPS is the best camera for the high precision time-based scientific projects. It includes two working modes. In Free Running Mode, the hardware records the GPS time and internal 1us calibrated time into the image header of every frame. In Multi-Site Sync Mode, users can control multiple cameras that are thousands of miles apart so that they start exposures at exactly the same time to the microsecond.
The QHY174GPS is the ideal camera for cooperative multi-site imaging of asteroid occultations.
The QHY174GPS is ideal for multi-site, high precision timing of exoplanet light curve measurements.
