For now the keyword looks like this when taking long exposures: DATE-OBS= '2021-11-05T22:02:00.034' / 2021-11-05T22:02:00.034
I guess the first time and date is when the exposure starts, so could we have the second part showing when the exposure is finished ? the above data is taken from a 120 second exposure.
EQ8, Small scope SW200, Big scope SW300, Xagyl FW, Guidescope Celestron 80mm, SX LodestarX2, SXVR-H9.
RPi4, Ubuntu Server 20.04.3 LTS x64, and many Arduinos..
