  Recent observations of Stephan's Quintet gave new indications on its
formation scenario. Older formation and a role of NCG 7317 should be considered
in revised numerical models of the compact group. Velocities of group members
to recreate are estimated from redshift measurements. Several effects
contribute to observed redshifts and a new effect is predicted to be the result
of the gravitational interaction between photons and constant magnetic fields
creating gravitational waves. The energy carried by these waves is manifested
as redshifts of photons. Cosmological simulations data are used to prove the
significant contribution of our effect. The analysis of synthetic observations
created from those simulations has shown that redshifts differences of
Stephanes Quintet members could be misinterpreted as caused only from Doppler
Effect. The revised models of the group should consider a new method to
recreate the formation scenario based on redshift patterns and not
mis-estimated velocities.
