LX200 ASCOM issue

[Philip Benson]

Hi Guys,

I don't know if you can offer any advice on this...

 

I was helping a friend on Friday evening in establishing an ASCOM connection between his 14" LX200GPS and Starry Night etc.

 

After trying a few USB/serial leads and drivers we managed to get a stable connection to the scope and this worked fine in SN. However We noticed a consistent error between the scopes actually pointing location on the sky and the shown position in SN. 

 

For example with the scope centred on M76 we slewed to a bright star in Cassiopeia.  The scope slewed fine and we took an image which confirmed the star was in the FOV.  However the red cross in SN was showing a couple of degrees off the star.  I tried to 'sync on' the target but the cross did not move. We slewed back to M76 and once again a quick sub confirmed M76 was back in the FOV.

 

So pointing is fine, but there is an error in the actual and displayed pointing positions. The same issue occurs when I closed SN and tried Maxim instead.

 

Any suggestions on how I can bring the scope and the software 'in line' with each other?

I don't have an LX200, but an initial thought, are all the various dates\clocks the same ??  as that usually screws things up....

OK Julian thanks for that.  The date and time on the scope side would have been set from the GPS fix so I will get Phil to check the date and time on the PC.
