QHY 174 GPS Cooled Monochrome CMOS Telescope Camera

The QHY QHY174 ColdMOS GPS CMOS astronomy camera is useful for imaging occultations, eclipses, meteors, and other scientific imaging requiring a highly precise recording of the time and location during observation on every frame.

The most interesting feature that this camera offers is the precision GPS time functions. The QHY174M-GPS will record the shutter’s exposure starting and ending time down to the microsecond. To guarantee the accuracy of exposures start and end time, the camera has a built-in LED pulse circuit for precise Calibration.

The QHY174M-GPS has a dual-stage thermo-electric cooling unit that will bring sensor temperatures down to -45C below the ambient temperature. It also features an anti-moisture control system that includes heated optical window and removable desiccant for the sensor chamber. The camera has our 4-pin QHYCFW2 filter wheel control port and a 6-pin autoguider port. The QHY174 also has an anti-amp glow function which reduces the IMX174 sensor amplifier glow shown in long exposures.

QHY174-GPS New Horizon Science Project
More than 20 QHY174-GPS cameras were selected by NASA's New Horizon Team for imaging an occultation by MU69. The data will be used for the New Horizon MU69 flyby in 2019.

As always OPT shipped on time. Camera seems to work ok and can get GPS data displayed in the frames, although this was only a test indoors with GPS antenna out the window. But the signal was able to stay locked. I was using Sharpcap Pro 3.1
