At all points I see a faint smear 1-3´(across) the roundish shape and glow like
a very dim lamp. Best found by finding a double-triangle asterism to its direct
N and then, on the right side triangle, scanning down a degree or so. I see it
very faintly with 10 x 50 Nikon Lookout II binoculars on a night like tonight,
moon down five days or so ago. Alpha Comae is a few degrees further S, S.E.
Filters UCH and Deep Sky show a tiny bit of definition. Still no outliers but
I get a granular view in this tightly compacted ball. Averted vision reveals
more of this and some small lanes. You know: a sandy texture.
I did NOT see the neighbor NGC 5053, even if at lower power (X25, X40)and with
a filter/ without, had the object right in the same ocular, to include the pair
a few seconds of arc N.
Burnham indicated that this globular has one of the lowest luminosities
This object is a bit of a challenge for light polluted skies. It took awhile to
