Inspired by Larrys work, I wanted to explore the options with the 645Z.

With no large-aperture wide-angle for that system, the ISO must be
stretched pretty far to make the dust lanes in the galaxy appear.
From looking at Larrys shots, I believed the quality of the foreground
would be the decisive factor for whether a result would be print worthy.
With that in mind, I took an extra long exposure at a lower ISO and
smaller aperture to see if they could be combined effectively in post.
That turned out to be more finicky than I had hoped, even with no
fluttering vegetation to move between or during exposures. Or maybe I'm
just too tired to be efficient now (it's 3 am).
Anyway, I think the technique may have some merit for the right kind of
foreground.
Sky exposed for 15 seconds at f/4.5 and ISO 12800.
Foreground exposed for 8 minutes at f/8 and ISO 800.
Tonal PP done in LR. Pasted the two together in photoshop.
