At f/4 you clearly need not worry about the mag 5.  I would suspect that mag
0.8 will not be a problem at f/4, but the nearly 0 mag one may leave a faint
trail.  Nothing that Photoshop won't cure in a minute or so.

I have found that satellites are an occasional irritation, but far from the
astrophoto threat they seem they might be.

I was at the Okie-Tex star party last October and that location has
something worse than satellites... airplanes!  Lots and lots of them.  That
part of Oklahoma is the airline crossroads of the midwest.  There were three
to six aircraft visible in the sky at all times.  They are brighter than
satellites and in spite of their sheer numbers, only one showed up on my
photos.  I was shooting all night for two nights using a 20 mm lens
(90-degree field) at f/4.  If I bagged only one airplane, I suspect you will
have little trouble with satellites.  Just avoid the predicted areas at the
proper times.
