Description

These Deepsky objects near Sagittarius seems to be very difficult to catch from central europe, because they never rise very high over the horizon.

I (as Sagittarius zodiacal sign) accepted the challenge!
I drove two times to a pass in central switzerland, where the light pollution in the south is quite low.
The first night after 1h clouds closed the view on Sagittarius, so i decided to make a second session a few days later. Luckily we had a clear sky at the upcoming Saturday 09.07.2016
