Personal Rating (for this aperture): B
Very nice to view so high in the sky from this (relatively) southern
locale. A moderately rich, large cluster, very easy to pick up in 8x32
binoculars.
In the scope..medium-bright stars, about 50 of them, many equal in
brightness, but some weaker members as well. Showed best at around
30x. Took up nearly the entire field of view at 32x (52 deg apparent
field size)
It was not round, but elongated somewhat, seemingly oriented SE-NW.
Thanks!
