Optical telescope with 3.75 ° field of view and pre-aperture slewing mirror with observation area of 50 ° ×120 ° for the system of observation of day time asteroids (the SODA project)
Abstract
We propose an optical scheme of a telescope with a field of view of 3.75 ° and 30 cm aperture for the space system for observation of decameter size asteroids (the SODA project). The main distinctive feature of this telescope is a pre-aperture flat mirror that provides an observation area of 50 ° ×120 ° and a repointing time between the adjacent fields of less than 3 s. A modern CMOS detector with a small pixel is proposed. Observable sky area when using 2, 3 and 4 telescopes are described. The advantages and disadvantages of each option are briefly discussed.
