It looks like the time is only accurate to the nearest second when I use my QHY 268M camera. There are a lot of decimal places but all populated with 0, e.g.:
DATE-OBS= ‘2023-05-22T04:35:45.0000000’ / UTC observation date
When I use my DSLR, the values are fully populated:
DATE-OBS= ‘2023-03-03T03:02:19.3345300’ / UTC observation date
Why is this?
