Hello all,

yesterday on 2009-03-17 I made some images from approaching asteroid 2009
DO111. The positions shown in my Guide8 were about 45 arcmin away from the
real position.

But if I used the positions of the ephemerides table calculated online on
http://www.cfa.harvard.edu/iau/MPEph/MPEph.html
the position was within few arcsec of real position.

Is there a way in Guide8 to get current positions with higher accuracy?
