NGC 6517 The field of view is very star poor and this dark field
may exhibit so much extinction that I am not able to resolve any
stars on the face of this globular.
100X--pretty bright, pretty small, round, much brighter middle,
easy to see as non-stellar. 220X--about all the power this object
can take, a little fuzzy at the edges, averted vision makes it
grow larger, no resolution. Core is elongated 1.5X1 in PA 45.
