Parabolic reflection

  1. Oct 15, 2005 #1
    In owning more than a few Newtonian telescopes in my life, I have just a little knowledge concerning parabolic mirrors. But I could use the help of experts in the field... I was wondering if a larger parabolic mirror could reflect a perfect, aberration-free virtual image, of a nearby object. For example, a viewer able to read a small-print book or any object that required magnification, a few feet away, with the viewer's eyes (the focus) being only a few feet from the mirror (using the off-axis portion). And optically, instead of the lenses in telescopes at the focus. Can this be done with a realistic focal length? And without coma issues or funhouse mirror warping closer to the edges? Thanks.
