Thanks Marco. I found I had two 960s exposures so I corrected them for darks and flats and squeezed out what I could for you.

The main reason I invested in my new system was to image very dim stuff in a moderately wide field. The Astrodon 50mm square 3nm filters are not cheap but their performance is superb. From my mildly light polluted site it was the only way to go.
This image shows just how much NII is out there and I have barely begun to look.
