The redshift observed in the expansion of the universe is called cosmological redshift and is a different effect from the the Doppler effect. https://en.wikipedia.org/wiki/Redshift

Ahh, apologies. Thank you! I'm learning new things! :-)

Yeah, I think I was referring to Doppler redshifts. Which is a very specific type of redshifts mentioned in that wiki article.

Again, thanks! :-)
