I used Sue French's list/map in the July issue of S&T as my observing plan.
Telescope: 15" f/5 Plettstone EP: 31,17,9,5 nagler
M19 - GC - 31, 17, 9, 5mm - Fairly even density of stars. At higher powers more stars seem to be resolved edges. Averted vision does not seem to help. Easily visible in finder.
NGC 6293 - GC - 31, 17, 9, 5mm - Visible as a round fuzz at lower powers. At higher powers stars can be resolved to the center.
36 Oph - D* - 17mm - Easily split golden pair.
NGC 6355 - GC - 17, 9mm - Asterism of 6 stars points towards this. On the edge of sparse star field. Gradually brightens towards center. At higher powers 2 stars can be resolved with averted vision.
Jupiter - GRS easily visible. No GRS Jr. Cloud swirls visible between equatorial cloud belts.
NGC 6284 - GC - 31, 17, 9mm - Circular blob steadily brightens towards center. At higher power a dozen or so stars are visible with averted vision.
Omicron Oph - D* - 17, 9mm - Easily split gold and white-blue pair.
NGC 6325 - GC -Dim circular smudge on sparse star field. No stars resolved.
NGC 6369 - PN - 31, 17, 9, 5mm - Smoky circular ring, broken at one end. Ultra block filter does not seem to aid. Very well defined edges.
NGC 6401 - GC - 31, 17, 9 - Dim smudge. Seems non-circular at higher powers. A very dim star was resolved off to one side just outside the zone of fuzziness.
NGC 6287 - GC - 17, 9mm - Somewhat bright. With averted vision is looks speckled with stars.
