Thanks Dave and Alex, I've enjoyed everything about this image; my re-acquaintance with the skies and my gear along with the acquisition of the sub frames as well as the processing.
I’ve just added another 30 minutes of Lum data (6x5min subs) from earlier in the same evening and it has made the overall image a little smoother, albeit subtly. This is also a slightly different crop to the original.
Cheers
Dennis
