I am glad that one turned out OK because the final 2 panel image was a disaster. I spent so much time trying to marry the two panels and concentrating on balancing the colours that the details slipped away....
I'll attach it here just for the record but will not put it up in higher resolution on my web site.....I have put so many hours into this that I now want to see the back of it and get on with a new project....whenever I can get a start! This is the second mosaic I have tried......I think I need to do a course to before I try another 
For those that have not seen it elsewhere, one reasonably good image came out of the 2nd panel: The Cygnus Wall.
Can be viewed (with all details) on my web site at this link: http://www.kinchastro.com/cygnus-wall.html
