Excellent work Rolf...been waiting to see this one and you didn't disappoint
Some deep (patient) imaging there and very interesting compilation too
Love the collection of background faint fuzzies, would make a nice wall artwork.
The thing I like here is you have gone very long in exposure but are not anal about getting low noise levels, the super depth and details are more important and make the image what it is, great stuff.
Cheers
Mike
