Sidereal time mismatch

Hi,

I am using Pothub to connect to my dome and my EQ8 Pro and when I connect it complains that the sidereal time of the mount does't match the computer - to the tune of over 12 hours (-44,000 seconds!).

I found an old post online that said Pothub uses the sidereal time from the mount or, if the 'Quiet' checkox is checked it calculates sidereal time from the PC clock.

I have checked that box and so now Pothub has the correct sidereal time. EQMOD is still 12 hours wrong. Pothub has a button to update the scope, but it doesn't let me - just complains about latitude, longitude and Data/time changes.

I thought EQMOD also calculated sidereal time from the computer. I know the synscan hand controller metadata is stored in the Windows registry so perhaps at some point erroneous values for sidereal time found their way there and somehow were never overwritten. The hand controller does, however, show the correct sidereal time.

How can I force EQMOD to recalculate based on the PC time?

Cheers,

Chis
