Re: Diverging lenses

2) Even today, the simplest telescope uses a diverginge lens for the
eyepiece. One advantage (in addition to extreme simplicity) is that this
produces a non-inverted image. (Modern high-quality eyepieces are quite
complex, but to first order are converging lenses, resulting in an
inverted
image.)
isn't the inversion caused by the objective lens?

The eyepiece (either cc or cv) produces a virtual and therefore erect
image of the real and therefore inverted image formed by the objective
lens.
