Object(s): M3 (NGC 5272)
Category: Globular cluster.
Class: 
Constellation: CVn
Data: mag 6.4  size 16'.2
Position: RA 13:42  DEC +28:23
Description:
49X: Large, round globular in Canes Venatici. At this low power no stars 
resolved but the cluster has a definitely mottled appearance.
98X: At 98X several outliers begin to be readily resolveable.
203X/244X: At these high magnifications M3 is a blazing ball of light, smoothly
going from a very bright center to an ever fainter background of unresolved
stars. ACross this background were seen many individually resolved stars all
across the face of M3. The stars, like in so many other globulars, seem to
form streamers radiating from the center, most notably to the south, northeast
and northwest.
There seemed to be an indentation in the northeast side of this globular not
unlike the flattened side seen in M13.
Wonderfull object.
