Hi Paul,
Have you considered the Tri-atlas?

Download the .pdf files for free -- all you have to organise is the printing and binding. N.B when I say free it is in fact a free and gratis download.
Maybe download a sample.pdf, take it to a professional printer and ask how much to do the "A" "B" and "C" set in A4 and other size options at 600dpi with various binding options and I'll bet it's cheaper than Uranometria even at large scale on top quality paper. When you discuss binding options I think it is a good idea to get something that will lay flat when opened.
If a few people get together and say a half-dozen or even a dozen were done, you might find it's cheaper again. The down-side is the Uranometria Deep Sky Field Guide won't interface with it.
Looks very good to me ...
Can't argue with the price.
Best,
Les D
