Navigate to Voyages: Distances to Galaxies (Links to an external site.). For each cluster in turn, click its link under "First, Observe and Appreciate" to open it in the SkyServer Navigate tool. Follow the directions under "Record the Redshift to Each Cluster" to get to redshifts of members of the cluster. I suggest that you calculate the redshift to each cluster by averaging five galaxies in each; this is a great time to learn how to use a spreadsheet. Note: Do not use the z value listed in the box on the top-right of the Navigate page. This is a magnitude, not a redshift. I know this is confusing, please feel free to send your concerns to the Queen of Astronomy.
