15. Casini is probably too close to get the whole thing "in view" at once.
Plus, its sensor has limited resolution. So if you want
more pixels (for a really finely detailed image), you need
to use those pixels on the sensor more than once.

Plus it lets you accommodate a wider range of brightness;
longer exposures on the dimmer parts, shorter (or stopped-down)
on the brighter.

With regard to the galaxy: From where would you take an
"actual" picture?
