I suspect that I have found the problem - or a problem at least.
My pc clock is gaining time!
I synchronised my pc time via the internet and then checked it with Verify the SkyX Time function - a difference of 6 seconds.
I started a calibration run - 5 minutes into the run, the discrepancy is 82.8 seconds!
How can a longT Point run accurately determine where the mount is pointing compared to where it should be if the time reported by my pc is wrong?
So it should come as no surprise that the PA report is all over the shop.
Has anyone seen this before? I've read about clocks losing time because of the CMOS battery on the motherboard running down but this clock is gaining time.
All very, very weird - I am running a fitPC2 with XP if that helps.
At least it is consistent - after 10 minutes it has gained 152 seconds ie 2.5 minutes
Is there a way to turn off the link between TSX and the pc clock? I can't find it if its possible. My thinking is a workaround would be to sync the clock then run TSX without it being infected by the dodgy clock. Just a thought.
