M-71 has been classed separately as a globular and an open cluster. To date I am not sure which it really is. Shaped like a giant comma, it has the fuzziness and sprinkling of stars of a globular, but it has the unspherical shape of an open. Is it a distant, dense open? Or a broken, dented globular? My own guess was that it is an open in front of a globular. In any case, M-71 is a small, beautiful punctuation mark in the sky.
