I use the database every night and other than small residuals which should be expected,
the targets are very much where they "should be". I am not sure why you would be seeing
any offset unless the TIME on your computer or telescope is set incorrectly....I have
noted that Guide is once again "losing an hour" compared to true GMT because of the DST
time change. I had to change one observatory computer TIMEOFFSET = 1 and then reboot to
have the correct GMT...that very likely could be the source of the offset.
