NGC 6559 - Eastern end of the Lagoon Nebula

            NGC 6559 is a star-forming region located aproximately 5000 light-years from Earth, in the constellation of Sagittarius.  It consists of both an emission -red and reflection - blue nebula region. 

It was a clear night with no Moon, but high level clouds and bit of wind in Melbourne last night, so I set up quickly and slewed the scope to NGC 6559.  This was a target we had done a few years ago, but only in broadband (RGB). Using narrowband filters, we were able to bring out a lot more nebulosity.
