NGC 6645 -- Open Cluster in Sagittarius
The Open Cluster, NGC 6645, was the perfect way to end my August 9, 2020 observing
session.  A collection of 70 stars between the magnitudes of 11 to 14 provided a satisfying
sight.  Only the brighter cluster stars could be seen directly, in the small refractor, with many
of the others fading in and out of my vision, creating a misty backdrop under the visible star
members.
