That's impressive for just one exposure - why aren't you stacking your exposures and why such high ISO?

Hi John.
Unable to stack one exposure only, Clouds.
I exposed one image for 30 minutes at ISO 400 it did not even come close to this one.

Sorry - the question was meant to be why did you only take one exposure and why not multiple exposures and stack them? You answered it, weather. With your set up, looks like heaps of potential there.

Cheers,
