[AZ-Observing] Re: NGC 6712 in Scutum

Do you have a image of the Coombs photo you can send? I did not see an arc
but instead a straightish like vein, but this may have been a function of my
telescope size and the fact that because it was visual I could not collect as
many photons as film or CCD. However, it was on the east side, unless my
directions are confused, not at all an impossibility. When I turn the clock
drive off, the west side of the cluster will be the first to hit the side of
the eyepiece field of view. Right, or am I confused? If correct, then the
dark vein was on the east side (i.e., the smallest area of the cluster is
east of the dark vein) and either Coombs' photo is oriented wrong, or ...?  I
did see a dark vein - power of suggestion? Possible, but I had observed it
for quite a long time, trying different eyepieces. If I can, which may not be
possible, I will observe it tonight again.
