The ED80 takes superb images. Just about everyone in astro imaging cut their teeth on one of these. I wouldn't sell mine, ever.
You also need a guide scope and guide camera if you're going to be imaging. You'll have no problems with this unit.

Have you thought about joining an astronomy club? Go to an open night and see first hand what is involved in astro imaging.
Slotting the camera into the scope and taking the pictures is the easy part.
The hardest is spending sometimes hours setting up the scope and aligning it to precisely compensate for the Earths rotation so you don't get the stars trailing in your images.
After a few weeks/months, when you have perfected your polar alignment and drift alignment skills, you can usually have your scope and mount ready to rock and roll in under an hour.
