Description

NGC 6770 and 6769 in Pavo
This was a real challenge that cost me a couple of nights.
The seeing has been a bit unstable recently and the group does´nt  really come up high even in the southern hemisphere.
I picked approximately 3 hours of the best frames between 1" and 1.8" for luminance and discarded probably about 10 hours of imaging time.
LRGB Ha 180 60 60 60 180 min.
