Agreed.

Probably means you were slightly off when you pointed the scope "north". Very easy to do. Lot of metal in the scope and tripod, so your compass can be affected. Doesn't take much to be outside of a 5 degree field of view on your finder. I seem to recall AndrewJ saying you can undo the locks and manually centre your first star, as it's only working out it's "model" based on how far out it is with the second star.

Two pieces of advice to get good pointing with an LX-90:

a. level the tripod carefully - use a bubble level

b. train the drives on a distant terrestrial

c. take your time accurately centering the stars, ideally with a reticle eyepiece

If I did the above, I was rewarded with accurate goto across the sky and tracking that would leave an object within the field of view of a 12mm eyepiece for hours on end.
