Love the resolution in the eagle itself. Great processing of this data. I saw your APOD the other day of the data your processed. That was very nice too.
What both Ken and John said are right on the mark when it comes to answering the question 'when is enough, enough?'. That has always been my guiding principle i.e I continue to get data (esp. NB) until I can suppress the noise sufficiently without overdoing the smoothing.
I processed this data set over the period of 3 consecutive nights. I dont think I ever publish an image at the moment I first decide 'its finished'. The cold light of day can reveal all sorts of horrors.
....and I certainly do not add old data on top of new data, but I have produced a hybrid image in the past where I have taken hi res data and blended it into a widefield image. Arguably, that could be seen as the same.
John - thanks for the compliment....I am hoping to get invited back one day!
Again, thanks for the comments. Glad you liked it.
