The Dolphin's Globular Clusters
The small constellation of Delphinus (The Dolphin) contain two Globular Clusters, one
behind the tail (NGC 6934), and one in front of its nose (NGC 7006). Both are distant
Globular Clusters, and both are suspected of being remnants of dwarf galaxies that
interacted with our much larger Milky Way galaxy. Neither cluster can be resolved into
stars by the 110mm refractor, but both were easily found.
To me these globulars appear almost as twins, although NGC 6934 is the brighter of the
two (it is closer to us). Both clusters at higher power (171x) appear to have subtle
glowing extensions originating from a weak core. These extensions may be star-streams
that are below the resolution of my telescope or have some other astronomic explanation
or maybe just my eyes playing tricks with me.
