Herm,

I agree that the PJ400 shot of M33 looks better.  I have not made a
habit of pushing E200.  I prefer to expose longer (even at f/4) to
record faint stuff.  With slide film I'd mask in a shorter shot for the
core.  Anyway, your final stacked imaged looks great.

How good is the Scanwit at scanning astro slides in general?
