Taken from my back garden in South East London, UK (Bortel 8). It has been cloudy for a long time so it has been really hard to get good data on this target. Can't wait for some better clear skies to get more data and reprocess it all. For now I am happy with this result. Using the narrow band filter is really a game changer for me.
