Description:
able to make out the outer shell perhaps 70+ stars using averted vision. The
core resembles a soft cottonball with whisps of stars making up outer shell.No
core stars could be resolved.only the outer shell of stars were visable. While
the gb is fairly bright the core is bright yet unresolveable perhaps due to the
massive amount of stars that range from magnitude 8 to 9 this GB is quit
beautiful and great object to view.
