I was having lots of trouble guiding with my LX200. The reducer was SBIG's
recommendation for a fix. W/O the reducer my guide adjust readouts were
typically >5's with many E's. Eventually it usually guided off the chip.
With the reducer, readouts were usually averaging 3-4's sometimes better
with good seeing. It fixed my problem.
