@Jared - I'd love you to take a look at this ........ The image I've uploaded is the first one from the night, so you can hopefully find it nice and easily. I've looked at the log and the times are just as the PC, so SGP is using the correct times..... so I have no idea why it is writing a completely different time to the fits header.......
Here's a link to my fits file https://www.dropbox.com/s/4g1nr19yfszln0f/Sh2-101_1800sec_HA_0015_ODK.fit?dl=0
