If astroimaging is only a second consideration and you want wow factor for the eyeballs then you might want to consider a 12" Dob and an Argo Navis for pushto. Then save your pennies up for a decent goto mount and refractor for astroimaging. Your pennies will also need to stretch for the imaging accessories; guide camera unless you want to manually guide, guidescope, guiderings, shoestring adapter to get your computer to talk to your mount, computer/laptop if you don't already have one.....etc etc
