The bright blue object in this blue galaxy is a blue foreground star. It has a spectra, and z=.003 and the zErr is only 0.00001
This is a star in the Milky Way. Your cross-hairs have to be dead center to see this.

Close, but not that close. It is an area of star formation and explosion in a nearby galaxy. NED has the bright region listed as a star, but NED can be wrong. Anyway, stars rarely have any sort of redshift or blueshift. They are z=0.000 Sometimes they can be z=0.001 but it might be an error of measurement, or sometimes a runaway white dwarf. But not z=0.003

Yes, you are right. Thanks. It is 41 million light years away. The z values for the other parts of he object are much larger, so we have #overlap_galaxy.. What galaxy? Is it cataloged?

I researched this more, and decided there is not even an overlapping galaxy. Another name for the this one is NGC 4861, and it is 48 million miles away, matching the z value well. So false alarm. Thanks for helping!
