Decent Night with some difficulties to start (NGC 6569 & NGC 6558, M19)

So why am I shooting these two obscure globular clusters (NGC 6569 & 6558) when I could be imaging the final Messier Objects in my catalog?  I was having go-to problems with my go-to mount during the beginning of the evening, my polar alignment app on my cellphone was not behaving properly and I though I fixed it but I don't think I did which is why my alignment was off.  Once I located an object it tracked perfectly.  I was looking for M69 in fact I originally thought this was it. Oh well.  I did better with M19.

NGC 6558 is a globular cluster, located about 24,000 light years away in the constellation Sagittarius NGC 6569, also a globular cluster located approximately 35,000 light years in the constellation Sagittarius (source: wikipedia)

Messier 19 (NGC 6273) is a globular cluster in the constellation Ophiuchus. It is about about 28.700 ly from Earth and is near to the Galactic Center (source: wikipedia).
