The LX200GPS creates a basic error map if you do a polar twostar align.
( Ie how far off the pole you are aligned ), and factors this into its object calculations. However, this only assists in goto accuracy. Doing synchs like you are doing may/will mess this up a bit, but it wont affect you if you are doing manual slews.
Once tracking again, this polar error isnt factored in, so its moot.
And anyway, if you find yr std gotos show bad accuracy later
a quick realign will fix it.

Andrew - thanks for replying again. When I previously used the word "aligned", I meant that situation when the scope's software and real sky were in alignment - i.e. the scope knew where it was in three dimensions (four if you include time) after a two-star alignment such that GOTO's work to within a standard 25mm EP's FOV. Being in polar mode, it should be taken that the fork axis was already pointing directly at the SCP - which is where I really should use the word "alignment" in its proper context I guess. Given this, a manual slew to an object, followed by a clutch re-lock should allow object tracking in RA irrespective of whether or not the scope was re-synced or not on that new object - no? Of course, it's easy enough to do that now!

Thanks for the help on the sync capability again. What a ripper!

Cheers
Chris
