Abstract
The paper is devoted to investigating the ways of development of the lightweight mirrors with imperfect optical quality but still suitable for being used in the telescopes with the primary mirror's aberration correction. The work involves the studies aimed at creation of the lightweight membrane mirrors with satisfactory optical quality and a suitable value of the F-number of around 1. As the first step, we demonstrate the possibility to control parameters of a pre-shaped membrane mirror by means of electrostatic field. It is shown that both the spherical component of the shape of the membrane mirror and its astigmatism can be controlled using the proposed approach.
