Image circle for Eyepiece projection

Just wondering if anyone knows a method to calculate the image circle diameter in a system using eyepiece projection ?

Can't seem to find any references to this anywhere .

In this case the EP's are Abbe Orthoscopic 2.8 or 5mm on a f7.3 refractor, 1100mm and the exercise is to attempt to calculate the largest CCD chip possible.

Thanks
