BK focuser worked well for me photographing the solar eclipse at prime focus of my 4". I don't know why EP would be much different. Once the BK's eyepiece is focused well to the camera's groundglass, you get a highly magnified image of that surface. The question of what eyepiece to use in the C-11 is different, and I have no experience with that.

Specifically interested in eyepiece used for projection work as my C-11 backdraw does not allow for the lower mm eyepieces I now have access too. Any additional further hints would be appreciated.
