Hey Glenn,

I don't know, this is about what I get with an 80-90
minute exposure at f/10 or 11. A 2 1/2 or 3 hour
exposure will show more, but at that point you've
pretty much soaked up the film and pushed you're
equipment to the max. I have a nice 3 hour exposure of
M51, but what I think Kevin wants to know is, will
stacking 2 or 3 shorter exposures give a superior
result to a single longer exposure.
