The third Sagittary triplet

Why did Messier miss the third triplet shown in today's (9 September) APOD? Was it that he couldn't resolve it, so that what he called M8 would be M8 and NGC6559 for us?
FWIW, through my binoculars, I only really see two blurries in this region of space (Triffid and Lagoon), so personally I don't begrudge him NGC 6559. Of course his telescopes do have a bit more aperture than my 10x50 binocs...
