Null Geodesics and Gravitational Lensing in a Nonsingular Spacetime

<div>Horizons and circular orbits for the nonsingular spacetime. The thin solid and dashed lines are for the outer and inner horizons, respectively. And the thick solid and dashed lines are for the photon sphere and stable circular orbit, respectively.
