Just found this post today. I rendered the animation at low resolution MPD 0.3, AA3. Surprisingly only took about 1.5 hours to render 200 frames, but I am calling that one monet-like nebula. I have 200 beautiful stills, but lots of flickering going on too in the animation.
Oshyans render looks impressive. I may give it a whirl at higher settings just to see. If it is 1 hour per frame, I might change that to the old pc and compare.
