It depends a lot on the darkness of the site and the brightness of the
target.  These samples might help you.  None of these are pushed or stacked.
I've also just completed several 45-minute shots on 120 E200 and 120 PPF at
f/6.4 with a refractor that look pretty good on the light box, but will not
get posted for another couple of weeks. 

Here's E200 at f/4, 60 minutes from a dark site:

E200 at f/3.3 (nominally f/4 T-stop), 20 minutes from a dark site:

E200 120 at f/5.6, 60 minutes from a dark and high site:

PJ400 (replaced PPF for a while) at f/2.8, 30 minutes from a dark and high
site:

PJ400 at f/3.3 (nominally f/4), 30 minutes from a really dark and really
high site:

PPF at f/3.3 (nominally f/4), 40 minutes from a dark and high site:
