Binocular star that seems too faint

Lawrence Jun 28, 2012

NASA has just published some fascinating info about this exo-planet and
gives a star reference:
HD 189733b

My first attempt to goto it via GOTO HD failed, so I deleted the 'b'.
This time it gives me a star in the vicinity of M27 as it is supposed
to. Unfortunately the star is supposed to be binocular visible and this
one most definitely isn't - according to Guide. So where is the problem
