Very, very nice Martin! detail is astounding but maybe missing something like Mike,Greg and Andrew mention?
I would like to see the Silicone added version!
Maybe because the NB gives such tiny stars it lacks that stellar look to it?

I think this will make a foundation for a real killer image with some more data added like some L or RGB maybe thrown in?

to bring back stars and color balance..
But I`m not one to judge on your outstanding work! I wish I knew just a fraction of what you would know!
Look out for the 2009 DM for this one!

cheers Gary...
