I'm not sure about the 5 SE, but a friend of mine bought a Nextstar 8 and
had lots of trouble getting used to the goto operation. The problem is
this: Rather than shaft encoders on the RA and Dec, these scopes use the
shaft position of the servo motors for reference, but the motors are
followed by a gear train with lash. To take up the play, or lash, the
instructions require that alignment stars be moved to the center of the
field from a specific known direction using the hand controller (like lower
right, for instance). After that the scope approaches objects accordingly.
Also, the internal batteries were drained within 20 minutes, so an external
battery was needed. Optically the scope is very good. - Paul Lind
