Don't forget the observations by Halton Arp. http://arpgalaxy.com/

You may like to have a look at the reports by Michael Mozina who listed a lot of evidence that there is no cosmological expansion. That is because all observations are still in line with the tired light hypothesis. And this redshift of light has been observed in laboratories, when light is moving through plasma. The problem is mostly the scientific community refusing to seriously talk about it.
