Could you please go back to the basics with this, er... setup? Does the
Neptune constitute the entire lens or is it a supplementary lens in front of
the camera lens? If the latter, what feature(s) does this setup provide?

Isn't the Neptune adjustable for differing eye spacing?
Regardless, how do you couple a 5mm eyepiece to a 30mm or so diameter lens?
