[g__day (Matthew)]

So from Tuesday night (200 star sky model) to Thursday night with 400 star model I am seeing varying pointing advice (about 8 arc minutes off where it said the refracted SCP was the night before) and a different pointing model solution.


If it isn't consistent how do I believe it?


Secondly I see the majority of my error appears to be in the North South axis - might that be DEC backlash or something else?


Lastly with TSX Tpoint am I best to set Backlash compensation in my mounts hand controller to zero and let Tpoint correct for this - or used software like PEMPro's backlash wizard to best tune my Dec settings in the mount before I let TSX and Tpoint work out an optimal pointing model?


Many thanks, Matthew
