Historical Research Notes / Correction for NGC 7089
NGC 7089.  Shawl and White's position, though correctly copied from their 
1986 list, is apparently 2 seconds of time too large.  The cluster's image on
both POSS1 and POSS2, though burned out in the center, is elongated and
symmetric about a position 33 arcsec west of the Shawl/White position.  I
suspect a typo in their table.
