Description:
Easy pickup in 50x. It shows a rather distinct elongation roughly NW-SE,
stellar core- actually looks like there's two stellar points in there, one a
foreground star and the other probably the nucleus. The one appears somewhat
to the SW of the nucleus about 45". In 100x I can tell that's definitely the
case. As a matter of fact that star to the WSW is brighter that the core, it
seems and about an arcminute, maybe slightly further away. On the opposite
side about 2' away there's a 12.5 mag star exactly in line with the other two.
A little something in between the core and that, slightly north, also. Can't
quite make out what that is.
