ED80 vs F4 150mm newt

I've been imaging with an F6 150mm newt but want a smaller focal length. About 60cm focal length would be nice. I currently easily do 5min exposures but never test beyond that before sky glow gets in the way. The weight of the ed80 is a positive for me but then I worry about how much longer I will need to expose each frame. Any experience with this would be appreciated.
