Anyhow just look at he guys who have a few post and there advice is spot on. The ED80 is a great scope, you could go a ed100 or ed120 pending your budget and a nice eq6 or heq5. The ED80 has a very nice FOV with a dslr sensor and gives a lot of forgiveness with guiding or without. It pretty much the prefect scope to start with and nearly everyone has who is into imaging, its just the best bang for buck scope there is and perfect for the novice and even seasoned veterans. You could jump into it deeper but it comes down to budget, and well since your hard on using your stock dslr i doubt you have pocket fulls of cash.
Anyhow pool the advise given here and the average speaks the truth, as for mounts it the base of imaging and well yer a heq5 is about the minimum you want, the eq6 offers a bigger payload though the heq5 is perfect for up to a max of a 8" newt (its pushing it to the limits but its proven and done) and will handle almost any APO refractor with in price reasoning to the mount cost just fine. The eq6 is better because it will handle a 8" newt alot better and there have being a few users who have put a 10" newt on them and imaged.
All this gear is synta aka sky watcher/Orion/saxon and is what you call entry level and will produce some very great images, though after this things will start to sky rocket price wise and you can worry about upgrading when your reached the maximum potential you can go with this gear, many years away trust me lol. After that Tak scopes, sbig ccd's and mx mounts ect will come into the picture, sbig ccd's and other ccd's more likely way before hand
