yep, you do need crosshairs... badly. Centering accurately will improve things a lot.
You also DO need to level the mount accurately, - (alternatively, tip the sky over to match your scopes angle..
)
and
after successfully finishing an alignment, when you "goto" an object,
you should use a very low mag lens initially, to see a large FOV in-case the object is not fully centered.
clear skies...
