AJ, I only was able to get a couple:
M 4
18? f4.5 Dobsonian, 135X; Dan Gruber: elongated bright core with about 6
mag 10 stars in a line parallel to the major axis of the core. Scattered
additional mag 10 stars, some in concentric rings/arcs generally
parallel to the central bar.
M 6
18? f4.5 Dobsonian, 135X; Dan Gruber: 2 parallel rows consisting of 18 ?
20 mag 8 ? 10 stars. End star of one row is distinctly red-orange. These
rows appear ?balanced on a fulcrum?, an inverted V ? shaped asterism
with its ?point? closer to the parallel rows. The asterism consists of 7
mag 10 ? 11 stars almost touching the row with the red-orange star and
off-center away from it.
Regards,
Dan

Why do I feel guilty you ask? Because I have to make the Call for
Observations for the month of August, knowing full well what the weather
has done to our observing habits. Unfortunately the call has to be made
and this is it. You will recall the constellation was Scorpius - the
logo for our club. If you have observations for the following objects,
regardless of their age, please send them in. For a reminder here is a
snippet, from the newsletter, of the objects and how to start hop to
them.
Let?s see what Scorpius has to offer. Naturally we will start with, and
do all of the Messier entries, beginning with M80 located 1.5° northwest
from omicron Scorpii. If you star hop this one, take a gander at the
Milky Way you traverse between the two. Next is easily located M4, in
the same finder view of Antares and 1.3° to the west. Both of these
globular clusters are easily seen in modest size finders. Next is a
planetary nebula, NGC6153, and is quite a hop from our last object. So
get ready for some fun here, it is 6.3° east of southeast from 3rd
magnitude eta Lupi and is not visible in moderate sized finders. Now,
going back to clusters find the magnificent NGC6231! It is a naked eye
galactic cluster located about ½ degree north of zeta Scorpii. Can you
detect the cluster without any optical aid? If you have binoculars
available, or can borrow a pair please do, give this area a nice once
over, you will be most happy to have done so. Moving on, towards the
tail, find M6, about 5° north of northeast from Shaula, or lambda
Scorpii. Finally, there?s M7, a scant 3.8° southeast from M6. Both of
these clusters are so large and bright you should be able to see them
without any optical aid. Can you see them this way?
Clear skies - and the sooner the better,
aj
