Here is a 5 sec single sub at iso 6400 with a 10" f5 newt and canon 1100d.

Lovely shot. I usually avoid ISO 6400 with my cheapo Nikon, gets very noisy, but might give it a shot to see how it compares to your shot here. I'll also need to align it a bit better than the other night, to see the difference in resolution. If the clouds ever bugger off I'll report back...
