I think that the majority of QHY174GPS owners use USB3 (with USB2 you cannot take full advantage of the cam, especially for stellar occultation observing).... do you know if people connect the camera with an USB 2.0 connector ?
Cheers, Christian

I've noticed two consequences to bad calibration, depending on how severely off it is:admin wrote: ↑Fri Apr 24, 2020 6:32 pm ... After a lot of investigation we discovered that if you don't have accurate calibration of the end and begin points then the output of the GPS system can be badly off (much more than you would think if you had the idea that the calibration was just fine tuning mechanism). ... The 'bad data' status means that the time that came out of the GPS reading is more than 24 hours different from the PCs system clock.

Are there other known consequences, especially ones that might not be easily noticed? Thanks.
- Completely frozen (unchanging) GPS time and BadCalibrationReduceEndPos (or sometimes BadData) error, or
- GPS window reported exposure (`Exp. (us)') differing greatly from the GUI-set Exposure -- like by a factor of 1.5x, 2x, even 0x different from what was set
