 I had tried to astrometry on the images, but gave up.
The exposure's are 60 seconds in length. The time is local time of the observatory, which is 11 hours ahead of utc. When I look at the fits file info in astrometrica, it gives the time of the start of the exposure in UTC.
Mike says this unid, is GSSAP 1.  Those darn things like to move around in geo.

The time is from the image name , but I don't know if it is accurate, and
how to adjust it to UTC.
Nor do I know the exposure - taken from two RA lengths !

Hi Kevin,
I tried to load one of the .fit files into SAOimage, but it does not show
any plate solution, so I saved screenshots of the left (4 sats) and right
(1 sat) halves of the 0309 image, and the relevant half of 0307 as jpg, and
submitted them to astrometry.net.
It gave me a (half) field width of 15', and positions around +19:14
declination - so what are the coordinates of the telescope ?
The same technique on the right half, and on the 0307, did not solve with
0.1 - 1 degree field !
Submitting a .fit file directly to astrometry.net looked OK, but did nor
solve !
