All-spherical telescope with extremely wide field of view

TL;DR

This paper proposes an all-spherical catadioptic telescope system made of a single glass type, designed for wide-field sky monitoring, with a specific example featuring a 400 mm aperture and a 30-degree curved field.

Contribution

It introduces a novel all-spherical telescope design using a single glass type for wide-field sky observation.

Findings

Design achieves a 30-degree curved field of view.

System uses only one type of glass for simplicity.

Example system has a 400 mm aperture.

Abstract

An all-spherical catadioptic system made of glass of one type is proposed for the monitoring of large sky areas. We provide an example of such a system with the aperture of diameter 400 mm and the curved field of 30 degree in diameter.
