  This paper aims to investigate the astrophysical applicability of the
electrically and magnetically charged black hole solutions obtained in a model
of nonlinear electrodynamics proposed by Kruglov (Ann. Phys. Berlin 2017, 529,
170073). Theoretical calculations of the bending angles and gravitational
redshifts from the theory of general relativity are studied numerically by
using the stellar data of charged compact objects and a hypothetical quark star
model. Calculations have revealed that although the theoretical outcomes differ
from the linear Maxwell case, the plotted bending angles coincide with the
linear case and it becomes hard to identify the effect of nonlinearity.
However, the calculation of the redshift has shown that while the increase in
the electric field leads to a decrease in the gravitational redshift,the
presence of the strong magnetic field contributes to the gravitational redshift
in an increasing manner.
