Description:
M69 -- located right next to an 8th magnitude star. I needed a little averted
vision to find this object, but once I found it, I could see it easily.
Looks quite diffuse.
M70 -- Took a little longer than M69 to see, but is pretty obvious once I got my
hands steady. Looks like a small,faint and diffuse patch of light.
M80 -- Quite a bright cluster (high surface brightness). Very easy to see and I
think I could see some condensation (or imagination?)
