Description:
Near to M46, but a rather different appearance. This has almost a butterfly
shape, with the eastern wing being larger and having more stars. The western
wing is primarily defined by 2 rows of stars, one having 3 fairly close
stars and then a farther one; and the other wing being 4 equally spaced
stars. There are a couple of noticable pairs in this cluster. One pair is
fairly close, est.10'-12', equal magnitude and blue. The other pair is
wider, the primary fairly bright and yellow with a much fainter
companion. This could be just an optical pair.
