M107 is a small, partially resolved globular. It is irregular
shaped, and at first glance appeared to have a dark lane. Closer
scrutiny showed a small, uninspiring "ink-spot" (free-form). Rounder
on one end, the other end kinda looked like it ended in claws,
giving it a slight crab-like appearance. Resolution wasn't complete,
but stars that resolved included two slightly brighter ones pretty much
near the center. Much smaller than M10 and M12 nearby, much less resolved
as well.
thanks!
