NGC 6520 --
Central condensation of the cluster shows approximately 22 brighter stars;
dark nebulosity from B86 appears to overlap into the cluster area itself.
Situated between NGC 6520 and a bright (7th mag) star to the north of M86
itself. The edge away from NGC 6520 (west) appears to be slighlty flat at at
Djorgovski 2 --
This eyepiece seems to be a very good match for this scope. With an exit pupil
of 2mm and a reasonably good (but not unmanageable magnification), it really
performs well on deepsky objects.
Now that I know where to look for this cluster, it's not difficult. In fact,
it's probably more obviou now than when I first saw it at the TSP. However,
that's probably due to familiarity with it, since the skies here (although not
bad) are certainly not Prude Ranch skies...
A slight little almost circular haze in the lower center of the trapezium
formed by one 8th and three roughly 10th magnitude stars. The haze appears to
be slightly oblong and brighter on one edge.
