This is the 6th installment of listings of Abell clusters of galaxies. It contains 29 Distance class 4 clusters of Richness 2 and up.

This list has 4 * clusters, and 2 ** clusters that are defiinitely worth looking at (zoom in). I believe A2029 is a fairly strong X-ray source, and it has a large central cD galaxy.

The rest of the clusters are currently not worth looking at, and I would not bother zooming out to see supercluster structure until the other richness classes are entered.

For an overview of Abell Clusters, with a list of the 4 Distance 0 clusters and the Virgo Cluster, see the "Abell Clusters" post here.

28 Distance 1 clusters are here.

22 Distance 2 clusters are here. There is also a discussion of "What is a cluster" in this post.

56 Distance 3 clusters of Richness of 1 and up are here.

123 Distance 3 clusters of Richness 0 are here.

From here on out, I will write some code (perl?) to convert the lists into KML format. I'm waiting for my son to advise me on the most suitable programming language.
