The fainter and more wide spread companion was easily spotted, even at 48x, but it took 72x before I got even a hint of separation on the 2 close ones. Going up to 120x I got a good clean, but close split - just a thin thread of black between 2 circles sitting one on the other, snowman style. A seemed to be a brilliant W, B either Y or O, and C too faint for me to tell.
