I still think there is a place for many subs. As in the hundreds if not thousands. What I've found is that for every double number of subs, there is half the noise. For instance 2 subs stacked is half the noise of a single one, 4 is half the noise of 2, 8 is half the noise of 4 etc right up to 1000 is half the noise of 500! So apart from killing the poor camera, why stop? lol.
Less noise means the image can be stretched more in the shadow areas so brings out fainter detail. (Taking the longest subs one can reasonably do without trailing of course)
Sorry Ray, I'm afraid we've totally hijacked your thread now.
