Any advantage to a field flattener for an ED120?

[bloodhound31]

G'day ladies and gents.

I'm just wondering if there is any way to enhance my Skywatcher Black-Diamond ED 120mm refractor.

At the moment I am just using prime focus with an Orion Starshoot Pro DSI.

Any suggestions to enhancing the optical train of this combination? Field-flattener? Can you get Barlow's in the 2inch?

Thanks mate!
