Description:

NGC 6093 – M80 – GC – Scorpius – Mag 7.2 – Found easily at 52x with the 27mm 
panoptic and didn’t try pushing the magnification past 100x due to seeing in 
that part of the sky.  Unresolved but very mottled.  Sits in between 2 10th 
magnitude stars, and is closest to the one on the east.  Dense core is 1.2 of 
the cluster, the other half is periphery.
