Description

This picture is processed and has approx. 50x more integration time compared to the single light !
60% of the lights where made at bortle 3 ambient and with very good conditions. Seeing was OK, but not the best. This is not so critical for 400mm focal length and 5µm pixels of my NEX5.
The others lights were captured in bortle 4 ambient with similar seeing.

In total I am happy with the result.
maybe double integration time would further reduce the noise and would give a more clear result.
