It should be noted, that while many people seem to call it "eyepiece projection" – it's not!
A
projection in the geometric/optical sense of "display of an image" always generates a picture on a flat plane. In fact I would say that afocality is exactly the opposite of a focused picture on a projection plane.
I'm sure this misuse of the term got started with people who were familiar with
(genuine) eyepiece projection. The act of taking astronomical photos with an eyepiece in the telescope reminded them of eyepiece projection, and they never stopped to think about what the words really mean.
