Some very nice images. I really like the OIII of the Helix, I have never seen just OIII for it before and it is amazingnly different from the Ha. The rosette and horse head were also very nice. The Oroin nebula was nice though the OIII could use a slightly longer exposure. Consdering the already very short exposure you used (and oh my did you collect a lot of data for 200sec), that isn't much of a stretch.

I am very impressed what came off this camera with such little exposure, virtually no noise! I am considering the Atik 428EX which is basically the same camera, just smaller. I will be using it at 400mm, same focal ratio so my field of view will only be slightly smaller than yours. Images like yours really  make me impatient to get it.
