Some pics I've taken with my 5DmkII and the 5DmkIII from my work.
All taken on a photographic tripod, no tracking but LOTS of stacking!
The one of M8 and M20 is 107 lights (and about 100 darks) at ISO25600 on the mkIII!!
Getting out and shooting these have made me realise that I've definitely caught the astronomy bug so I've finally taken the plunge and ordered an ED80 on an EQ5.
There are quite a few more, as well as info for each shot, on my blog:
