I imagine the E100VS works pretty good for astrophotos considering its 
relative the "E200" is primo choice.


But what about the velvia 50?

Star trails?

Brian:
E100VS and Velvia don't work well for guided, long exposure astrophotography.
Velvia produces 'greenish' sky backgrounds and suffers from reciprocity 
failure.
E100VS has much more neutral sky backgrounds and works very well for star 
trails.
In fact the star colors in the trails really pop-out.
