I keep looking at this image Martin and it really does look astounding.
Something is bothering me though..?
In your description of how you processed your recent NGC 55 image you mentioned that you layer in a version of the Lum that has had the minimum filter and deconvolution applied. It is my experience that the minimum filter actually imparts or adds false detail in an image by skewing the stars and particularly the nebulosity, in an intricate spider web like fashion creating what apears to be enhanced fine structural detail but in fact is simply an artifact of the minimum filter process and not true structural detail.
It looks as though you have done the same here in this image to enhance the details and there is no doubt that the result appears highly detailed but is it "true" detail or simply enhanced processing artifacts contributing to an illusion (at least in part)?
This said and if we are describing the overall visual artistic impression aspects, then this image....it is a friggin corker
