I reckon the ED 100 is a great compromise; the extra focal length will allow you to image many galaxies and smaller planetaries, and you can speed it
up later with a focal reducer to f7.65 which will allow you to image some larger nebulae, it also has a 36% larger light grasp than the ED 80, which
is good for visual work as well.
