At the moment you just need a T-Ring and T-Adapter, and later on you'll probably want to get a coma corrector and autoguiding.

Yes, thats it, I was able to get prime focus with just the t ring and adapter, but i wanted to use the barlow as a zoom of sorts... is that not possible? Same with using the eyepiece for projection, I want to get in closer or at least have a say in framing an image. Perhaps this is just done with cropping later on?
