Thanks to both of you....
I will be using fast lenses for this, 50mm-105mm,
which will all be of the milky way region of course.
I remember taking a 25 min shot of the scutum through
my 105 on hypered tp with some lumicon film, equiped
on the lens was a lumicon Ha filter and the shot came
out almost completley black.
I had to hold it up to a lightbulb to make out what i
captured.
The deveopment time was around 5 mins, but thats with
the lumicon hypered TP.
Ill be giving it a shot tonight ..my skies are the
clearest most transparent skies I have seen here or
anywhere in a looooong time.
Thanks for the info!

I forgot to directly mention this, but since you're doing wide field targets, the part of the sky will have a big influenece on exposure and developement times. The Southern Milky Way-Scutum area is the brightest area in the sky and requires much less exposure time.
